The best stuff I have ever used is called "Magic Mix". It has some rabbit on the bottle. It is a liquid polish that works wonders for removing stains. My Weld rims look brand new after everytime I use it. Some people like Mothers but that stuff is impossible to remove. The Magic Mix comes off just as easy as it went on. I am at work right now so when I get home I'll get the 800 number for you to find a local dealer.
