No kidding guys. I am prepping a 2009 Mazda for sale and used Mean Green to try and clean the wheels. I can not honsetly say that it did anything at all. Well, there was a bottle of Lexol sitting there from a few hours before when I was detailing the interior. What the hell! I sprayed the Lexol onto the passenger side rims and let the tan foam sit a about half a minute and then went to work with my brush. I must say that the Lexol did better job than over half or 3/4's the various products I have tried on wheels. The Lexol truly seems to break down the dust and emulsify it. The Mean Green really did nothing that I could tell. The Lexol is pricy but hey it did work pretty darn well!
