Will this damage paint if I use it to remove concrete stains

Concrete
Asked by: Jose
It is possible that it can. Your best best is to test a small area first to see how it will react to it over the concrete and/or stone.

32 oz. Fast-Acting Phosphoric Acid Cleaner is rated 3.9 out of 5 by 21.
Rated 5 out of 5 by from Another good product for cleaning rusty motorcycle gas tanks Here is another good available product to clean out rusty gas tanks on motorcycles, ATV's,scooters, go-karts etc....... 1 bottle will do most rusty gas tanks motorcycle size.... Be careful and research on google safety requirements and disposel methods of used acid.... Also flush tank out really well with clean water and then add a half box of baking soda to fuel tank and fill with water half way and slosh around good to neutralize acid, flush again with clean water, dry as best as can , then dry even more with MEK, Acetone.... Tank will not rust easily after all this, phosphoric acid treats metal to slow rust process down....... cheers!

Rated 5 out of 5 by from safer to use indoors I used it to clean concrete floor prior to installing porcelain tiles. I cut it with a bit of water and it cleaned the floor real well. It was not a very strong odor with a fan running and a window open. Actually pretty tame and I felt much safer than if using muriatic acid.

Rated 4 out of 5 by from Mineral Buildup gone! We had a stone shower with terrible mineral stains on the slate tile when we moved in to our home. It took two treatment to remove all of it, but I was so pleased with the results. I truly thought we would have to replace the tile, nothing else even came close to getting the residue off the slate. Follow the directions and make sure to keep the area well ventilated.
