After much searching i found a product that carquest puts out called TP-725 Aluminum Cleaner And Brightner. This stuff is awesome. The guy at carquest said he cant keep the stuff in stock. I tried everything I could think of to clean my wheels but nothing worked. Now my wheels look like NEW. I thought that I would recomend this product. Costs about $11.00 a gallon. Well worth the money. Be carefull applying to wheels. This stuff is very acidic.
