The Mueller Kueps Inner Rim Cleaner, No. 433 507, prevents corrosion-related distortion of wheel bolt tightening torque and allows the user to completely remove burnt-on corrosion. Designed to clean the inner wheel contact surface, it should be used only on the inside of an aluminum rim, particularly the inner area, prior to wheel balancing. Due to the porous abrasives and a cup shaped grinding plate there is minimal dust, and the Velcro adhesive makes the tool easy to change out. The Inner Rim Cleaner was developed as a followup to the company's Wheel Hub Grinder, to address the need for removing corrosion buildup on enlarged aluminum wheel hub diameters (of 75mm) and inner rims.
