Just tried this stuff and am impressed. PO put aftermarket wheels on my pickup, which I probably wouldn't have done, but that's how it came. They've looked like junk for the past 5 years or so that I've owned it and I have tried to get them clean, but was just using elbow grease. Sprayed this stuff on there and my wheels are shiny and silver color again (better than I've ever seen them.) The fronts had massive amounts of brake dust that would not come off and the back were just dingy. Only thing to remember with this is to use it only on wheels that do not have a clear coat.
I was nervous at first to use it because I know it has hydrofluoric acid in it which is scary stuff. That was used in a metals plant that I used to work at in the pickle room. it was mixed with nitric acid and it could eat any metal and the hydrofluoric acid really messes you up if you get it on you. I don't know what concentration this cleaner has, but it was really a spray on and rinse off deal. I made sure to wear my nitrile gloves
