what are you guy's using to clean your Radir wheels, the aluminum part of my wheels gets stains from most anything i use, scared to use somthing that may harm them.
i've always used simple green or spray magic. spray it on, hose it off, wipe it down, polish to taste. your centers are already dull, but that doesn't mean not to be gentle. try to get as much crud off of them BEFORE using a rag so that the crud doesn't make it worse. micro fiber cloths are wonderful if they were polished and sealed, the cleaning process would be a little simpler.
Give Rich a call at the shop 1-866-334-3470, He can tell You exactly what to use since they're His wheels...........
