i have some racing hart c4's, and i have noticed that i am building up gunk in between the lip and the rim face. Also the lip has some crap on it that will not wash off nor will come off using wax. I tried to see if it would come off by trying to scratch it off using my finger nail. But the god damn finish looks like may have come off. The color of the lip where i scratched it, is now lighter than the rest of the lip.

Is there any product made for polished lip's? Cleaners and waxes for wheels?

 

Wax is not an abrasive chemical, it will not clean it off. When you wax it, you're more likely trapping the dirt with the wheel.

Have you tried using any wheel cleaners? A clay bar might help. After you're done cleaning it, try a wheel sealant so the dirt will come off easier when washing in the future.

 

Clean the rims with a degreaser and use a clay bar on them. That should get most of the stuck on particles off. Then use any metal polish (Flitz or Mothers) to get the shine back.

If their panted and clear coated rims, I would use some Klasse AIO to protect them...
