I have found amazing results with Wink rust remover. The directions say avoid contact on any surface not stated in the directions. Then its says, clothes, carpet and white sinks and toilets, white is very not descriptive, but I assume it means white porcelain.
I found the active ingredient is HYDROFLUORIC ACID and DENATONIUM BENZOATE.
HYDROFLUORIC ACID isn't that very potent stuff?
Anyway, my question is, What is the reaction that clears rust in
5 seconds or less? Rust stains just disappear, what do they become. I checked into chemistry usenet groups and didn't find one appropriate. I found two without any threads.Mikek
