Has anyone used CLR Metal cleaner to clean their aluminum alloy wheels? The problem was that my brake calipers froze which grinded fine metal dust from the rotors on to the wheels. Being that its winter it immediately rusted and which then stained the wheel. I know CLR household cleaner removes rust and this is their equivalent cleaner for cars but does it work? Does it damage the coating on the wheel? The wheels are not chrome, they have a brushed metal look. They seem to have a coating on them but I am not sure its laquer.
