How does Stain Solver remove stains?

Stain Solver removes stains at the molecular level. The oxygen ions in the solution blast apart stain molecules rendering them invisible. Stain Solver does the exact same thing for odors to. It rips apart odor molecules so your things smell fresh.

What are the ingredients in Stain Solver?

Stain Solver is simply a dried form of hydrogen peroxide and soda ash. That's it. That's why it's so pure. For more info, here's the MSDS.

What can I use Stain Solver on?

You can use Stain Solver on anything that's safely washed with water. There are hundreds and thousands of things that are safely cleaned in water. Be sure to read the next FAQ.

What can't I use Stain Solver on?

Do not use Stain Solver on woolen items or silk. Do not use it to clean redwood. Don't use Stain Solver on leather, as it can take out the natural pigments in leather.

What stains will Stain Solver clean?

Stain Solver will clean all organic food stains. Stain Solver can clean grease, especially if you mix in just a little bit of regular liquid dish soap. Stain Solver can clean red wine, kid's juice and Kool-Aid stains, etc. Body oils, blood, grass stains, etc., can all be cleaned with Stain Solver. Remember, you have nothing to lose using Stain Solver as the garment, carpet, tent, etc. is already ruined until such time as it's clean.

What stains will Stain Solver not clean?

Stain Solver won't remove rust, hard water stains or some very harsh chemical stains. Once again, since an object is stained, you have nothing to lose trying Stain Solver. Thousands of customers have sent success stories about stains that wouldn't budge with other cleaners, but Stain Solver worked.

Is it safe to spray Stain Solver on your pet to get rid of skunk smell?

Tim Carter, founder of Stain Solver, answered this question.

It is SAFE to use Stain Solver on pets to get rid of skunk smell. I've done it several times on my own German Shepherd that loves to chase them in the NH woods.

The TRICK is to apply the Stain Solver solution to their faces with a hand wash cloth dipped in the solution. Do NOT let the solution get in the pet's eyes or on mucus membrane in the mouth.

From the neck on down, I just saturate the fur with the solution.

Make sure you have HELP with someone holding the dog. Wear goggles because if the dog SHAKES, you don't want the solution in your eyes!

Get the fur wet with the solution and keep it wet for about 5 minutes. Rub it into the fur. Add shampoo if you want to help.

The longer you allow the Stain Solver to soak on the fur, the BETTER the results will be.

It may take two cleanings to get rid of remnant odor that you can miss.

Will Stain Solver remove odors?

Yes. Stain Solver removes odors by breaking apart the odor molecules. It's so powerful it will even remove skunk odor in minutes.

Will Stain Solver remove color?

Maybe. Stain Solver is color safe in most situations. Stain Solver will remove the color from items dyed with vegetable, fruit or other food dyes. Stain Solver is so powerful that if you accidentally spill the powder on a wet garment, it may whiten that spot. Always soak colored garments in water where you've dissolved the Stain Solver. You can apply a paste to pure white garments if you have a tough stain.

How do you use Stain Solver with a carpet shampoo machine?
Can I use Stain Solver with carpet shampoo in a machine to clean my entire carpet?

It's best to make up a solution of Stain Solver and apply it with a hand-pump sprayer to the entire carpet before you turn on the shampoo machine. Allow the Stain Solver solution to soak into the carpet fibers for 20 - 30 minutes before starting the machine. The trick is to use HOT water, mix the stain solver into that and stir till dissolved. Any excess solution from the hand-pump sprayer is poured into the machine reservoir and you add the carpet shampoo as you would normally. After the shampoo solution dries and the carpet is dry, vacuum up the white powder residue.

Can Stain Solver remove old stains in clothing?

More often than not, YES! Let the stained item soak in a solution of Stain Solver liquid overnight. If the stain is still there, increase the concentration and try it again. Continue to increase the concentration until you succeed or fail. Remember, you have NOTHING to loose. Until such time as the stain is removed from the garment, it is headed for the rag pile. 

Will Stain Solver work on synthetic material, such a Spectra sail?

Yes, It will work fine on any synthetic material.

Will Stain Solver kill fungus on socks?

Question: Chlorine bleach kills fungus. I need to ensure my socks contain no fungus, but I have some black socks that need to be treated. Can Stainsolver be as effective for colored fabrics? Will it kill the fungus like it apparently does for mold? If so, would you please recommend the ounces per gallon to be used.

Answer: Yes, it will clean your black socks.

I would add 6 ounces (3/4 cup) of Stain Solver to one gallon of water. Stir to dissolve the powder.

Dump in the socks. Let them soak for 6 hours. Come back every hour, if possible, and stir the socks as the oxygen gas will float the socks to the surface.

You want to make sure the socks stay down in the solution.

After doing this, wash them as you would in your washing machine.

What is the ratio of oxiclean to Stain Solver that contains the same amount of active ingredient?

Full Question from customer: "I will be using this primarily for laundry applications. I am accustomed to regular oxiclean that I bought at Sam's. What is the ratio of oxiclean to Stain Solver that contains the same amount of active ingredient? I love that it doesn't have any of the brighteners, fillers, etc., but want to make sure I don't use too much. Does this make sense?"

It makes PERFECT sense.

There are two factors that differentiate Stain Solver from OxiClean. First, our active ingredient is made here in the USA. We're not positive, but we're almost certain that OxiClean purchases their chemical from Chinese suppliers. It may not be as pure as the one made here in the USA. We suspect that from all the bad reports we've read about Chinese dog food, Chinese drywall, Chinese toys that contain lead paint, etc.

Second, we're almost certain that OxiClean puts in only half as much active ingredient as we put in our Stain Solver. We put in the maximum amount as allowed by Federal DOT laws.

The bottom line is that I would try to use only 1/3 as much as you used to use with OxiClean and tell me what your results are. Remember, you get the best results by always using Stain Solver as a pre-soaking agent. Be sure to use your washing machine's soak cycle and allow my product to soak in your clothes for an hour or more before advancing to the wash cycle.

I was wondering if I could use Stain Solver in a common carpet cleaning rental machine?

You mix up the solution, one-half cup to a gallon of hot water, and make sure the powder is fully dissolved. Put the solution in a garden hand-pump sprayer.

Spray the solution on the dirty carpet. Spray it everywhere you will operate the machine. Dampen the carpet well, but not so wet it soaks into the backing or pad.

Wait 15 minutes. Pour the remaining solution in the carpet machine. Add carpet shampoo. Operate the machine per it's instructions. After the carpet dries, ANY white powder can be vacuumed up easily.

Can laminate floors and hardwood floors be cleaned with Stain Solver?

Yes, but you must mix the solution and apply LIGHTLY with a damp mop. Do NOT flood a laminate or a hardwood floor with the solution. White residue that appears after it dries can be removed with clear rinse water and a damp mop rinsing frequently.

Is Stain Solver safe for cleaning unsealed natural stone floors?

It's totally safe to use it on travertine, marble, granite, slate or ANY other natural stone. Sealed or unsealed.

Can Stain Solver be used to clean travertine floors?

Stain Solver can be used to clean travertine floors and the grout between the pieces. You use the same method I show in the in the video just below in the next question.

Is Stain Solver safe to use on marble?

I always suggest doing a TEST in a small area that's under a piece of furniture or in a corner.

Wipe the area first with a damp paper towel and then buff it dry to show what the gloss is of the marble.

Take 12 ounces of hot tap water and pour in one tablespoon of Stain Solver. Stir until completely dissolved. Pour some of this onto half of one piece of marble. Allow it to sit for ten minutes and lightly scrub it with a scrub brush. Pat it dry with paper towels.

Rinse with clear water. Dry the marble with more paper towels and allow to fully dry. Check for an improvement in cleanliness and check to see the gloss is the same as when you started.

If the marble is duller, it could be because someone placed a glossy sealer, wax or polish on the marble. Stain Solver is such a powerful cleaner, it can remove these products.

How do I use Stain Solver to clean an entire carpet rather than spot clean?

Mix up the Stain Solver. Use one-half cup - 4 ounces - per gallon of warm water.

Stir until completely dissolved. Make sure there are no crystals undissolved.

Pour the solution into a garden hand-pump sprayer. Saturate the fibers of the carpet, but not so much as it soaks the carpet backing.

Allow solution to work for 20 minutes before using a traditional carpet shampoo machine. Any leftover Stain Solver solution in the bucket or sprayer can be used in the carpet shampoo machine along with normal carpet shampoo soap.

Shampoo as you would normally.

If any white powder is on the carpet once dry, just vacuum it up.

Will Stain Solver work on colored grout?

Stain Solver will clean colored grout and will not harm it. Watch the following video, the same process can be used for slate.

Will Stain Solver work on epoxy grout?

Stain Solver will NOT harm any grout. Epoxy grout being the most durable. The trick is to put in the shower drain and FLOOD the shower basin with my solution. Mix 3/4 cup per gallon of hot water and dissolve the powder.

Let the solution soak for hours, scrubbing from time to time.

As for the walls, you mix up the same solution and pour it into an old spray bottle and spritz the walls, keeping them wet with the solution for up to an hour. Not easy. Then you scrub from time to time.

Another method for wall cleaning is to mix 1/2 cup of Stain Solver per gallon of water with a squirt of Dawn Dish washing Liquid.

It's lots of work because many people let the mold go too long and it penetrates into the grout.

Will Stain Solver clean grout on an interior slate floor?

It will absolutely clean the grout and not harm the slate.

Is Stain Solver safe for sealed Saltillo tile floors?

You bet it's safe! Stain Solver can't hurt any tile or grout.

Beware though, it does such a great job turning it back to original, you may think it ruined it! We get that complaint frequently - people forget what the floors looked like when new.

Will a floor scrubbing machine as work well as a scrub brush?

A customer asked when using Stain Solver to clean tile grout, will a floor scrubbing machine work as well as a scrub brush? Sure would take less muscle! The answer is you bet the machine will do better as long as the bristles of the machine contact the grout. That's mission critical! If the bristles only contact the top surface of the tiles, the grout won't get scrubbed.

Why are the edges of the tiles darker after cleaning?

A Stain Solver user commented "Cleaned grout on ceramic bathroom tile on sink counter. Mixed solution and followed instructions on bottle. The edges of some tiles have darkened. The tile is an off white color. Please help my wife is going to kill me!  See attached picture."

There could be several reasons for this discoloration. First, the edges on some inexpensive tiles are not glazed. This allows water to soak into the tile creating the dark coloration.

Another possible cause is the ceramic tile was made with clay that was not as dense or hard as it should have been.

What do I do if Stain Solver doesn't appear to clean my grout?

Question: I bought two containers and it did not clean the grout.  You can see in the photo (not posted here) how it somewhat cleaned some parts but not others. I soaked it with new batches.... And scrubbed. It did not come clean.

Answer: I'm really sorry you're disappointed. From the photo you sent, it appears to me the product did a fantastic job. I can clearly see where about 85% of the grout looks brand new. It's VERY clean compared to the random darker spots.

That tells me two things:  Those areas didn't get scrubbed as well or the product didn't soak long enough there.

I ask that you do a cool test to prove the product works and you'll have perfectly clean grout. 

Mix up just ONE standard 12-ounce glassful. Fill the glass with HOT water. Add one tablespoon of Stain Solver powder. Stir till dissolved.

Pour one-half the glass slowly on the center of the floor where you took the photo you sent me. Use your fingers to gently spread the solution so that it stays in the center and does not migrate. Be sure it's on areas where the black spots are. WAIT 30 minutes. If it soaks in, add more so there is some standing solution on the grout the entire time.

At the end of 30 minutes, scrub the area HARD with a very stiff brush that has bristles that are no longer than 1/2 inch. Be sure the bristles contact the grout. Some grout that is deep never gets touched by the bristles. Add more solution to make sure there is plenty as you scrub. RINSE well.

Let it DRY for one day and look at the side-by-side results with what you have now. You should see a dramatic difference and the black spots should be gone.

All you have to do is follow the Return Policy if you want the refund we offer. I know you want clean grout, not the refund. Try the above and please send me another photo. It's important you wait the day to see it dry.

Is Stain Solver safe for linoleum flooring?

Stain Solver will make your linoleum or sheet vinyl floor look like NEW. As with any liquid, don't let it puddle on any seams or at the edges.

Do a small test area and watch what happens. Take a 12 oz drinking glass of warm to hot water and put in one tablespoon of Stain Solver. Stir till dissolved. pour half the glass onto the dirty linoleum. Swish it around till about 1 square foot of floor is covered. Let it stand for 10 minutes. Come back and lightly scrub and rinse. That area should look fantastic.

Can Stain Solver be used in Swimming Pools?

NO!! If you mix Stain Solver in a pool, it can create dangerous deadly chlorine gas. The oxygen bleach can react with the chlorine already in the pool water and release chlorine gas.

Can I use Stain Solver in my septic system?

Stain Solver is TOTALLY safe to use in septic systems. It actually enhances the biologic activity of the beneficial bacteria in tanks to help break down solids.

Chlorine bleach is the worst thing to put in septic systems. It's so toxic, it kills the beneficial bacteria in the tank.

Pour 3 - 4 ounces of the powder into the toilet bowl just before bed. Do NOT place the Stain Solver in the toilet tank! Do this treatment every two weeks.

I pour it in my toilet and let it sit for about five minutes. I take advantage of this time to help it clean the toilet. Use your normal toilet brush to clean the bowl. Then flush the toilet. After the tank fills, swish the brush in the clear water of the tank to remove any of the powder from the brush. Then flush the toilet again to ensure all the powder makes it into the septic tank.

Is Stain Solver safe to use in gray water systems?

You bet it's safe to use in gray water situations. When you mix Stain Solver with water, all you get is *more* water, oxygen and soda ash. Soda ash is a naturally occurring mineral that contains just carbon, sodium and oxygen. The oxygen in the solution will *help* breakdown the gray water making it safe for the environment where it discharges outdoors.

Is Stain Solver safe to use around plants and trees?

Yes. Stain Solver is safe and non-toxic around all vegetation. When mixed with water, the solution adds beneficial oxygen to the soil.

How much do I need?

Deck Cleaning: 2 lbs. of Stain Solver will clean 300 to 500 +/- square feet of deck surface. Dirty horizontal deck surfaces sometimes need a second quick cleaning. Don't forget railings! Each lineal foot of average railing has 4 square feet of surface area.

We find that the average deck - 15 ft. x 15 ft. - requires a minimum of 4 lbs. of Stain Solver. This does not include the railings. If you have railings on 3 sides, you would need another 2 lbs. of Stain Solver. Order 8 lbs. for the average deck.

It is best to order an extra container in case of spills or extra dirty conditions. The product has an indefinite shelf life, so it will not go bad if the lid is kept tightly sealed.

Laundry Use: 2 lbs. is enough to salvage and restore 20 or more T-shirts. This is based on restoring them one at a time in about a gallon of water. If you have 20 shirts in a load of laundry, it will go farther. (I'd add one-half cup to a full load of laundry and it's IMPERATIVE you set the cycle to soak and have the Stain Solver work on the clothes for several hours before you switch to the normal wash cycle. The longer you allow the Stain Solver to SOAK - for up to five hours - the better your results will be.)

General Purpose Cleaning: Keep 4 lbs. on hand for carpet or fabric emergencies.

How do I use Stain Solver?

Stain Solver works best mixed with water, warm water for most stains. The mixing directions are on the label. It's best to store Stain Solver in a cool, dry place to extend its shelf life. More helpful tips can be found on this Use Instructions page.

How do I apply Stain Solver?

There are three ways to apply Stain Solver: vertically, horizontally or soaking.

For the vertical application, pour the mixture in a spray bottle, and spray it on your walls. Keep walls wet with the solution for up to 30 minutes before you begin to scrub.

For the horizontal application, mix Stain Solver per the directions on the label. Then pour Stain Solver over the item to be cleaned. You want to saturate the object. For floor tile grout, be sure that the solution ponds on top of the grout. Add more solution if it soaks into the grout.

For the soaking application, mix Stain Solver per the directions on the label. Make sure the bucket or bowl you use is big enough to hold your item. Then completely submerge your item in the Stain Solver.

For all applications, make sure your item is completely dry before applying Stain Solver. If your item is wet, it won't be able to soak up the Stain Solver as well because it will already be saturated with water. Let the Stain Solver sit on your item for up to six hours to get maximum cleaning benefit. If your stain is still there, use a scrub brush or toothbrush and gently scrub.

I followed your instructions, but my item is not getting clean. What's wrong?

You may not have used enough Stain Solver for the amount of water you had. If scrubbing, the scrub brush bristles may have been too short and not contacted the surface you were trying to clean. If the Stain Solver is old, it may have lost it's power. You may not have allowed the Stain Solver to dissolve in the water. You may not have let it soak long enough.

What is the shelf life of Stain Solver?

Stain Solver can last up to 18 months if kept cold and dry.

What are the container sizes for Stain Solver?

The 2.2 pound Stain Solver is sold in a one-quart container (32 oz).

The 4.5 pound size is shipped in a two-quart or half-gallon container (64 oz).

The 9.2 pound Stain Solver is one gallon container.

The 18.2 pounds is a two gallon container.

The 50 pounder is in a five gallon bucket.

What's the best scrub brush to use?

We feel the best brush is one with stiff nylon bristles that are between 3/4 and 1-inch long. The brush in these photos is great for exterior scrubbing of concrete, brick or other masonry surface. Similar smaller brushes for interior tile can be found in many grocery stores or businesses that sell household cleaning tools.

Stiff nylon bristle scrub brush Stain Solver Scrub Brush

What is your return policy?

You can read our full Return Policy. But basically, you must return your order within 30 days to receive a refund. There is a 25% restocking fee, and you will not be credited any shipping fees.

Can you ship Stain Solver by U.S. Mail?

No, we can't ship Stain Solver by US Mail (USPS) with the exception of the new 0.4-pound size (SKU SS01). This size is small enough that it can be shipped via USPS anywhere in the USA. The other sizes of Stain Solver have to be shipped via UPS Ground. Federal regulations requires that oxygen bleach be shipped via ground only. No air shipments. Thus, all shipments go via UPS Ground.

To what areas do you ship?

We only ship to the contiguous 48 states in the USA and into Canada. Orders shipped to Canada do not qualify for Free Shipping and are subject to local tariffs. Note that the new 0.4-pounder can be shipped via USPS to any location in the USA.

When will my order ship?

We ship all orders usually on the next business day after they are received. We do not ship on weekends or on holidays observed by UPS. You can visit to see all scheduled holidays they observe and when their trucks are not on the road.

We are not allowed to ship overnight. All shipments must be in trucks. Stain Solver is not allowed on airplanes.

How much is one ounce of dry measure?

1 oz. of Stain Solver in dry measure is equal to 2 tablespoons.

What is the white residue on my wood after I clean it?

If you rinsed your wood really well with clear water before the Stain Solver solution dried, the residue is probably sun-damaged wood fibers that often look like peach fuzz. You can see it in the photo below. They are white because the sun bleached out all the natural color. This typically happens with both pressure-treated pine and cedar decking and cedar fencing.

To remove these fibers, allow the wood to dry completely, then use medium aluminum oxide (light brown in color) sandpaper to remove the fuzz. You may have to start with coarse grit if the fuzz is really bad.


Can I use Stain Solver to remove the odor from my dishwasher?

Yes! Pour in one ounce of Stain Solver powder into the soap container in the door and close the soap dispenser lid. Pour an additional ounce in the bottom of the dishwasher. Set the control to SOAK. Let the machine run in the SOAK cycle and do not allow it to drain. Let it sit for 3 hours. Then turn control to Pots and Pans and run the machine.

Can you send me a small sample of Stain Solver?

Because Stain Solver is such a powerful cleaner, we're not allowed to send the larger sizes through the US Mail, they have to be shipped via UPS. We do have a smaller size that can be shipped via US Postal Service. Just order the 0.4 lbs bottle to give Stain Solver a try.

How do I use Stain Solver in my laundry?

Stain Solver works BEST as a pre-soak agent. We recommend that you pour 2 oz - one-quarter cup - into your washing machine before you add clothes or water. Set the control to SOAK. Allow the clothes to soak for an hour or two, then set the controls for a normal washing load.

Can Stain Solver be used in the newer front loading washers?

Yes, you can!!! Just put the Stain Solver in the slide-out tray where you normally add the liquid or powdered soap. If your machine has no Soak Cycle, I suggest choosing a longer washing time to get MAXIMUM benefit and cleaning power from the Stain Solver.

Do I need to use Stain Solver each time I do laundry?

You don't have to use it each time, but using each load helps keep clothes perfectly clean and it makes them smell as fresh as they can. Stain Solver gets rid of tough body odor molecules.

Is Stain Solver a liquid or a powder?

Stain Solver is a powder that you mix with water. It dissolves faster in warm or hot water, but can be mixed in cold water. Once mixed and dissolved, it only produces stain-fighting oxygen ions for six hours. Because it's a powder you mix with water, it's highly concentrated and has a very long shelf life.

Does Stain Solver remove mold and their spores?

Stain Solver cleans mold really well. It blasts it apart and then when you scrub and rinse, it's gone. Will it come back? It almost always will return because mold spores are present everywhere in and about your home and possessions, and you probably have a food source. The ONLY way to stop it is to make the area or article is permanently dry.

Will Stain Solver clean mildew and calcium stains in a shower?

Stain Solver will NOT remove hard-water stains. You need white vinegar to do that.

Will Stain Solver remove stains from the toilet bowl?

It will remove organic stains from a toilet bowl, but not hard water stains. Just take 1/4 cup and pour it into the bowl. Let it sit for an hour. Then scrub the bowl with a toilet brush. If stubborn hard-water stains are there, you need to read this column:

Will Stain Solver work on marble?

Yes, Stain Solver can be used safely on marble.

Will Stain Solver remove rust?

Stain Solver can remove rust in certain situations, but generally the answer is no. Remove rust from concrete with oxalic acid and water.

Can I use Stain Solver to clean tarnished sterling silverware, platters, bowls, etc.?

No. Stain Solver is an oxidizer and will actually tarnish or deepen the tarnish on sterling silver items.

Do you have an MSDS sheet for Stain Solver?

Yes, you can download our MSDS sheet.

Will Stain Solver clean my pool filter? It's full of calcium, flocculant sludge, and old algae.

Stain Solver will remove the algae and should do wonders on the flocculant sludge. But it will not remove any hard water deposits. Two out of three isn't bad! You may have to use a weak solution of muriatic acid and water - 20 parts water to 1 part acid - to remove the calcium.

Is Stain Solver safe to use on outdoor Teak Steamer Chairs?

You can absolutely use Stain Solver on any teak wood. It's been used for years to clean premium teak on the decks of ships and boats.   Your chairs are going to look gorgeous. Once clean,  I'd seal them with Extreme Defy in any color but clear. Perhaps you'll like the cedartone color.

Will Stain Solver remove or damage stain or paint on my deck or siding?

Read the information on this Cleaning Stained Wood page.

When can I apply Stain Solver to a wood deck?

Stain Solver should NOT be used on freshly sealed decks. Use Dawn dish soap for general cleaning. Stain Solver is to be used AFTER the deck sealer has failed.

Will Stain Solver hurt my Trex or composite decking?

Absolutely not. It will make the Trex, or any other composite decking look like new. There are no harmful byproducts that will hurt the decking. The test is this: If you can safely wash something with water, you can use Stain Solver on that item. The only exceptions: silk, redwood and wool.

How do I apply Stain Solver to a wood deck?

I prefer to use a large brush or a mop. You want to get large amounts of Stain Solver liquid on the deck surface. Hand pump sprayers often apply too little solution to the surface. If you must use a sprayer, make sure the product has dissolved completely or you will clog the nozzle! Also, be sure you spray on lots of liquid. 

Why do you say to work in the shade or on an overcast day?

Hot deck surfaces and sunlight can evaporate the Stain Solver solution before it has a chance to work.

Do you have to scrub wood decks or will Stain Solver do all the work?

After the product sits for 15 - 20 minutes, I like to lightly scrub the wood with a scrub brush on a pole. You do not need to scrub hard. The brush removes the sun damaged wood fibers and completely loosens the dirt, mildew, and algae. Always scrub before rinsing with a garden hose.

Should the Stain-Solver solution be applied to a wet or dry deck?

Always apply the solution to a DRY deck. This allows the solution to soak deeply into the wood fibers. A wet deck prevents this from happening making it very hard for the Stain Solver to deep clean the wood.

Is Stain Solver safe to use on all wood, including pressure-treated decks?

NO! Stain Solver can darken redwood. Redwood that has not aged is the most vulnerable. Always test Stain Solver on a small remote part of the redwood to see what happens. The darkening happens rapidly and can make the redwood appear almost black. Use Oxalic Acid to clean and brighten redwood if you want to be completely safe.

Stain Solver is safe to use on all other woods, including cedar and pressure-treated decks. Stain Solver can be used on bare wood also, except as noted above. 

Will Stain Solver remove my applied stain?

Stain Solver is strong enough to remove your applied color stain from your deck. If the Stain Solver can get under your deck sealer, or if you don't have a deck sealer, it will remove the stain and leave you with bare wood. Always test Stain Solver on a small remote part of the deck to see what happens.

Can I apply Stain Solver using a pressure washer?

No. You will dilute the solution too much using the suction tank on a pressure washer. Apply the Stain Solver solution with a mop or hand-pump sprayer applying generous amounts of the solution.

Why did my wood fence and deck develop black spots after cleaning with Stain Solver?

The black spots were probably there on the wood before you started cleaning. They were covered by existing dirt. Usually the black spots are concentrations of mildew that requires a second cleaning with additional scrubbing.

Will Stain Solver damage a neoprene, rubber surface?

The full question was - "I have a neoprene roof surface directly below the deck (the deck supports sit on the neoprene). Since rubber is a natural product, will Stain Solver damage the neoprene?  Also, I've flipped the boards over and I'm having to sand out the lines (stains) where the boards sat on the supports.  Will Stain Solver take those out as well?"

Answer: The Stain Solver will NOT hurt the rubber. It should clean it. My product should help with the stains on the underside of the boards. It may take two cleanings, but it should work.  Remember, apply to DRY wood for the best cleaning results.

Should the deck railing be cleaned before or after the deck?

If you clean the railing and the cleaner drips on the decking and sits there - which it will as you work, it will DEEP clean where it dripped. When you clean the deck later, the spots will be visible.

If you clean the deck first, then the rail - keeping the deck rinsed off as you clean, NO SPOTTING.

This is the same trick as washing walls down. If you ever did that years ago starting at the top and working down, you always ended up with streaks.

Wash from bottom up and no streaks.

Can Stain Solver remove fuel oil stains from a deck?

How do I mix Stain Solver for cleaning a roof?

Mix it the same way you do for a deck - 6 ounces of Stain solver per gallon of water. 8 ounces per gallon for tough stains. 

What is the best way to clean the roof?

Brush off all loose debris and scrape off any large deposits of moss or algae. Apply the solution with a pump sprayer to cool shingles! If the shingles are in sunlight, the solution will evaporate before it can work. Keep the roof surface wet with the solution for at least 30 - 45 minutes. Scrub lightly with a broom or brush and rinse well with water. Try a test section first using just one quart of solution. If it is still stained, boost the concentration to 8 ounces per gallon of water.

Realize the wet moss WITH STAIN SOLVER on it will be exceedingly slippery. Wear fall protection gear, work from a dry roof, work from a ladder that's laying on the roof. Do NOT step on the wet moss - ever.

Removing Algae Stains from Roof Shingles.

Removing Algae Stains From Roof Shingles

Will Stain Solver kill roof moss?

No. Roof moss is a small plant that needs to be removed with a powerful stream of water aimed down the roof, or by brushing the moss with a street broom or some other stiff brush. Stain Solver can then be used to clean the roof after the moss is out of the way.

Can I store the Stain Solver solution after it's been mixed with water?

Once the Stain Solver powder has been mixed with water, it only produces the stain-fighting oxygen for about six hours. Mix only enough that you can use in an hour or two.

When you mix Stain Solver with water, it immediately starts to create oxygen gas. The gas starts to pressurize the container, either a sprayer or other container. This pressure could FORCE the liquid out of the bottle if it is sealed.

NEVER store the Stain Solver solution that's been mixed with water in a sealed container. It can explode as the oxygen gas builds up in the container. If using a sprayer, be sure to release pressure in the sprayer every 30-minutes.

What's the best way to store Stain Solver for a long period of time?

If you store Stain Solver in a freezer, it can last for up to two years. Heat and humidity degrade Stain Solver. A partially filled container of Stain Solver may start to cake and harden over time. If you want to store an opened container of Stain Solver, if possible, place the open container in a freezer for about 3 hours. While the container is still in the freezer, immediately place the lid tightly on the container. This process removes the humid air from inside the container that accelerates the caking. Stain Solver stores best for long times frozen or cold. It's still good if it cakes, so long as not too much caking. But my freezer trick will eliminate the caking.

Heat degrades Stain Solver. It's not recommended that it be stored in areas where the temperature is above 90 F for an extended amount of time. Keep Stain Solver is a cool basement or other cool spot.

My Stain Solver has been on a shelf for a year. How can I tell if it's still good?

It's easy to see if Stain Solver still works.

Turn on the hot water at your kitchen sink. When the water is HOT, fill a regular CLEAR glass with the water.

Set it on the counter. Wait for the cloudiness in the water to go away. That usually takes about 30 seconds.

Dump in 1/4 teaspoon of Stain Solver.

If you see cloudiness happen immediately and tiny bubbles start to come to the surface of the water, it's still GOOD.

It might. Stain Solver is such a powerful cleaner it can easily remove sun-damaged and oxidized paint pigments outdoors. Cheap and inexpensive paints are often the ones that can suffer damage.

I want to use Stain Solver on something that's not listed here. Is it safe?

Stain Solver generally is safe to use on anything that's water washable. But since it's a powerful chemical, you must test it first and make a determination if it's safe to use. If you're not sure and you don't want to cause any damage, it's best not to use any chemical. All chemical cleaners and soaps have the potential to damage anything.

What kind of liability do you have if Stain Solver damages me or my possessions?

Stain Solver is a chemical cleaner. Just as you use chemicals in and around your house everyday, you need to assume liability for your actions. We can't control how you mix it, how you apply it, how you store it, and whether or not you read all of our information. As such, the only liability we can offer is the purchase price of the actual product.

You need to realize that by you using the product, you understand that the product may harm you, your possessions or anything that it comes into contact with. This is no different if you were to use chlorine bleach, oven cleaner, oxalic acid, muriatic acid, paint thinner, label-removing solvents, abrasive cleaners, etc. All of these things can be purchased and used by the average homeowner, and all of them can cause damage to surfaces.

Can I mix Stain Solver with chlorine bleach to get extra cleaning power?

NO! DO NOT mix Stain Solver with chlorine bleach. It will liberate poisonous chlorine gas.

How do you measure Stain Solver?

How much should I mix at one time?

Only mix as much liquid as you can use in 1 to 2 hours. Once mixed with water, Stain Solver only has a "pot life" of about 4 - 6 hours. After that time, it no longer produces the stain fighting oxygen ion!

I used your Stain Solver and there is a white film on my tile. What is wrong?

The white residue could be small undissolved pellets of Stain Solver and/or dried soda ash. In many cases, you can use a vacuum cleaner with a brush attachment to remove it. If that doesn't work, use generous amounts of fresh rinse water to remove the residue. If the rinse water is not changed frequently, you will continue to see residue once the rinse water dries. You have to change the rinse water frequently! The white film is soda ash. Here is a test. Take a wet paper towel and wipe ONE tile only. Then immediately, take a dry paper towel and dry it WITHOUT touching adjacent tiles. The dried tile will shine. Proof that soda ash is being left with using fouled rinse water. 

Can you clean cedar shakes/siding and vinyl siding with Stain Solver?

Stain Solver easily cleans cedar shakes/siding and vinyl siding. It will remove sun-damaged stain and sealers, algae, dirt and grime. You apply the Stain Solver solution with a hand-pump sprayer.

Can you clean aluminum siding with Stain Solver?

Stain Solver will clean aluminum siding. However, the paint used on aluminum siding can oxidize and suffer UV degradation over time. Stain Solver can remove this damaged paint.

How do I apply Stain Solver to a vertical surface?

A customer asked "if you had any hints as to the best way to apply the Stain Solver solution mixture to the hand rails and pickets in an efficient manner, so I won't waste any more than necessary."

The best way I've found is to use a simple hand-pump sprayer. If you adjust the nozzle so it creates a medium spray, you can coat all the vertical pieces of wood quickly. The trick is to work in the shade and with no wind or as little wind as possible.

The solution will evaporate quickly from vertical surfaces, so having no sun and wind helps you. Keep the wood wet for 10-15 minutes before scrubbing. You'll have to spray the surfaces at least 3 times to keep them wet.

Cleaning Painted Siding

Full question: "I have latex-painted hardboard siding that is darkened by mildew, particularly on the north side of the house. Are the directions as to how to use Stain Solver on this siding any different from those for use on cedar siding?"

Stain Solver is such a GREAT cleaner it can and will remove oxidized and sun-damaged paint pigments. Since it's on the north side of your home, this may not be too much of an issue.

But remember that not all paints are created equal. This means cheap paint can be damaged by great cleaners.

You should start SLOW and use reduced concentration of powder in water.

Mix 1/4 cup per gallon of hot water. Use it on a small out-of-the-way area. I would try a spot about 1 foot by 1 foot. Apply with an old paint brush, keeping the siding wet with the solution for up to 30 minutes. Rub LIGHTLY with a grout sponge and rinse well with a garden hose. Let dry and check for erosion of paint finish.

How do you make a paste using Stain Solver?

You probably used cold water or you added too much powder to the volume of water. Always use warm water with the Stain Solver unless you're trying to get out a blood or grass stain. Use cold water for these stains. You can always mix the solution with warm water to get the powder to dissolve, then add ice cubes to chill the water.

How do I apply Stain Solver to wall tile?

Unfortunately with a little difficulty. Once mixed, Stain Solver has the consistency of water. I use an old Windex or other bottle with the spray handle. Spray the solution onto the wall. This can be sprayed on your ceiling if it tiled. Just be sure to WEAR goggles. Don't get the solution in your eyes. You have to keep the tile WET with the Stain Solver solution for up to 30 minutes.  The longer you let it sit - even up to 45 minutes - the less you have to scrub. Then dip a scrub brush in the solution and scrub.

It's not easy, but it usually produces great results.

Be aware that hard-water deposits WILL interfere with cleaning. I TEST for this by taking one paper towel and saturating it with white vinegar. Apply it to the tile and grout like a piece of wallpaper. Pour a little more vinegar on it and let it sit for 30 minutes. Come back after the wait period, take off the towel and SCRUB the area where the towel was with a stiff brush and some cleanser. Rinse and let dry. See if that looks better. If so, then you must do this to all the tile before using my stuff.

Do I need to reseal the tile and grout after I clean it with Stain Solver? Does it "eat" the sealer??

Here's my take on grout sealers. I would never again use a grout sealer. Why? Because they can interfere with cleaning. Let's say you spill red wine on sealed grout. The wine seeps into the grout at the crack between the tile and the grout. The Stain Solver solution has to do the same - squeeze through this tight space. If there was no sealer on the grout, the Stain Solver solution can readily soak into the grout cleaning it easily. Now that you know Stain Solver works, you have no fear of spilling things on the grout.

One last tip, if you use Stain Solver in your regular mop water, letting the solution soak for 10 minutes BEFORE rinsing, the grout will look great all the time.

Will Stain Solver harm ceramic tile glaze?

Dear Tim: Some of my Stain Solver got on my floor tiles rather than just on the grout. The tiles effected have a lighter color than the rest of the tile.  Is there some way this can be repaired to look like the rest of the tile? Thanks. - Carol W., Auburn, AL

Dear Carol: I had this issue with another woman about two months ago. We traced it to her using floor cleaning products in the past that didn't actually clean the floor and left thin layers of the cleaning product with residual dirt. She had multiple thin layers of dirts on her floor, but she actually though the floor was clean.

It's "impossible" for my Stain Solver to remove the glaze or pigments from floor tile. Ceramic tile is one of the most durable flooring materials made. That's why you see them in restaurants and other commercial buildings.

That being said, here's what I want you to do:

Get a 12 oz regular glass and fill it with hot water. Take one tablespoon of my Stain Solver and dissolve it in this water. Stir till completely dissolved.

Take two clean dry paper towels and fold them over on each other so they completely cover a floor tile about 8 x 8. Pour half the glass of solution onto the paper towels while they are on a tile making sure the towels are completely saturated. Let sit for an hour.

At the end of the hour, remove the paper towels and add more solution to the tile. Take a stiff scrub brush and scrub the tile. Immediately rinse the tile with clear water and dry with paper towels.  

The tile you worked on should look like new.

Will Stain Solver clean concrete?
