Wow. I mean.. WOW! Alright, so I tried out the wheel cleaner expecting results like everything else I've ever used. This means... the wheels clean up like if you'd just taken to them with a pressure washer. Clean, but no big whoop. Here's the series of events and the end result: Factory wheels on a 2000 Mustang. I'd sprayed wheel cleaner on them last week bought from the local auto parts store. Forgive me but I don't recall which brand, but it was not the cheapy type - it was one of the main ones. I had just finished giving the car a quick wash and did the quick wheel cleaning to get rid of some of the brake dust. Spray it on.. let it sit while I do the other wheels, and then wash off with the hose at it's highest setting. So the wheels were not TOTALLY dirty, but certainly not clean in the least. I apologize for the poor picture, but rest assured the wheel was dirtier than it appeared. After receiving the Brown Royal Wheel Cleaner I finally had a chance to use it. I gave it the same chance as the other wheel cleaner. No scrubbing, no brushing, etc. I sprayed the two front wheels with Brown Royal Wheel Cleaner and, as per the instructions, let it sit for a couple minutes. The stuff sprays on brown.. kinda cool! After the few minutes, I took the garden hose and with the nozzle on the power setting (it's no pressure washer, let me tell you!) hosed the cleaner off. I go back to the first word of this post... wow!
