Unlike the majority of wheel cleaners on the market today Meguiar's Hot Rims product is safe to use on all wheel types even split rims, polished alloys & chrome finishes. Simply apply Hot Rims to a cool wheel & let the highly effective neutralising agents penetrate brake dust & grime to break down contamination & loosen its hold. Then hose away the residue to reveal the lustrous surface underneath. Safe on ALL WHEEL SURFACES including aluminium, clear coated, polished & unpolished chrome. Removes tough road grime, water spots, mineral build up & brake dust.
