My LR2 has a real penchant for producing brake dust which darkens my wheels within 2-3 days after cleaning. I saw this new 2009 product mentioned on a blog the other day and decided to give it a try. Holy cow!--- it works better than I would have imagined. After almost 2 weeks including 2 major rainstorm, my wheels are clean -- well at least cleaner than they would have been normally. The stuff was a little hard to find (3 auto store visits) and while it dries clear, it does leave a slight residue if you look very closely. But man it works. Better than blackened wheels at least. Not sure how it would do on chrome wheels given the coating effect, but on aluminum cast, it is great.

Probably really toxic and poisoning the environment. But my wheels are clean! See below

Do not touch the wheel once you have applied the product as this will remove the coating from the surface of the wheel.

I'll give it a try once I can take the wheels off to clean them.
