Īsern is a highly concentrated wheel cleaner that cleans and turns iron deposits purple. It will safely
remove brake dust and road grime from wheels, brake calipers and other surfaces, without removing waxes, coatings or sealants applied to them. Īsern leaves a clean, degreased and smear free
surface behind. It is safe for bare metal wheels.
 
Spray on surface and leave to react. If needed, agitate with a soft brush. Wash away with a pressure washer. Do not leave to dry on surface! Do not apply on tires!
