Use the power and rotary action of your drill to clean your wheels, tires, rims, lug nuts, wheel wells, mud flaps, exhaust pipes, truck bed, undercarriage and engine parts faster, more effectively and with a fraction of the effort compared to cleaning by hand. RotoScrub works with ANY drill (cordless drill not Included). This 2-piece drill brush combo kit includes a super extended long brush with soft bristles (safe on all types of wheels) + extended reach brush with heavy duty bristles (not recommended for painted wheels). RotoScrub is great for cleaning cars, trucks, motorcycles, trailers, RV's, campers, ATV's and just about any other on or off-road vehicle. RotoScrub can be used with any soap or cleaner. Always wear eye protection. Consult your power tool manufacturer for additional precautions.
