Jeff_Seymour, your chrome wheels may be coated, perhaps clearcoated. You DO NOT want to use an abrasive chrome cleaner on those. I suggest Simple Green in a spray bottle and a non-abrasive cloth or sponge. You may want to seriously consider getting Axxix Deluxe Advanced brake pads and eliminate 95% of the massive amounts of dust the BMW pads give off.
