Well I cleaned the wheels this morning after 700 highway miles and 4 track sessions, the front wheels were filthy. I tried hosing them off first but that didn't do much for either the Wheel Wax wheels or the Collinite wheels, just knocked anything loose.
I then washed them with water and Mothers Car Wash and they cleaned up just about the same. The Wheel Wax wheels did seem to have less of the little balls of brake pad material stuck to them and what was there came off a little easier. Over all the Wheel Wax shine was about the same but there was less of the little balls of pad material and what was there didn't stick quite as hard.
