I have a 323ci w/sprt.pkg(17"rims). I clean my car every Friday. But by Sunday my rims are already dirty from the brake dust. I was wondering what you guys have found to work best to remove the brake dust and to give the tires a nice shine. Ive tried a couple of different products, but they dont seem to work well. Thanks in advance for your help. Bimmer Tech 00 323ci 84 323i
