The best thing to do is to apply a good coat of wax to the wheels. Tht wax makes it hard for the dust to attach and pit your wheels. When you wash the wheels just use soap and water. Depending on how much you want to get envolved with it, you shoud clean the inside of the wheels as well. I rotate my own tires and every time I do, I take them out in the driveway and scrub the inside of the wheels really good, then apply wax to the inside and out.
