I need help cleaning my rims badly. since we had a real rough winter here in MD i think the road salt had a lot to do with my problems. i have what looks to be small nics in the wheel itself and break dust has filled them making my C2's look extremely dirty. anyone know what to do? i tried 2 cleaners and still no luck. anyone know if maybe a good rubbing with steel wool will help or just **** things up more?
