Isern Wheel Cleaner
Īsern is a strong wheel cleaner that turns iron deposits purple as it cleans. It safely removes brake dust and road grime from wheels, brake calipers, and other surfaces without removing any waxes, coatings, or sealants that may be applied. It leaves the surface clean, degreased, and smear-free. It is safe for use on bare metal wheels. To use it, spray it on the surface and allow it to react. If needed, agitate with a soft brush, then rinse off with a pressure washer. Be sure not to let it dry on the surface or apply it to tires.
