Clean Rust Stucco Vinyl
Clean rust from stucco and vinyl using oxalic acid. Stain Solver will not clean rust from any surface.
Oxalic acid is quite toxic and it may remove the sheen from vinyl siding.
It will not hurt cement stucco, but it could harm painted stucco requiring you to repaint.
Do a Test First
Be sure to perform a test on a very small area when trying the oxalic acid solution. Mix up according to the label instructions and use a cotton swab to test a tiny area.
