Bilt Hamber Auto Wheel 5L Iron Contaminant Remover and Alloy Wheel Cleaner

Auto-wheel’s pH neutral formulation reacts with the oxidising surface of the metallic particle rendering it water soluble, the rapid removal of this microscopically rusted surface reduces the embedded particle size and releases it from the surface, unlike acids this method is harmless to the wheel’s finish and in fact so fast it cleans more effectively – the reaction is seen by a rapid colour change from clear to deep red, after which a simply hose or rinse leaves the wheel spotless. In severe cases a brush can be used to assist the process.

Auto Wheel was the winner of the Auto Express BEST BUY award for 2012
