I use that Blue magic shmooze on my american racing rims... it works waaaaay better than that turtle was crap. Windex will work, but it will just clean them, rim cleaner usually has protectant in it to prevent rust and futur gunk from clinging, so use windex so your rims look good on your way to the auto store to buy the real rim cleaner..
Hey, thats what we are here for. I am sure someday you will be helping me with something!! Actually... I have this strange rash... if you could take a look... Good luck with keeping those rims clean, takes alot of work...
