Review on P21S Wheel Cleaner Refill, 1000 ml - Effective & Reliable Automotive Care by Mike Hernandez

A little disappointed that it doesn't work better. I have wheels with old lapped brake dust and it still hasn't come out. In fact, in my experience, this thing doesn't work any better than almost any pre-made cleaner, including things like Purple Power, Super Clean, etc. I find the ZEP cleaners available from Home Depot work better and cheaper.
