Four-piece cleaning and detailing kit includes 4 different size and shape automotive/boat wash and detail brushes. The white brushes have soft bristles for scratch-free cleaning and scrubbing. All brushes feature rugged steel shafts with a (quarter inch) quick-change attachment for fast change-out of components. Clean and scrub aluminum, magnesium, chrome, clear coated, and painted rims and wheels for cars, trucks, and motorcycles. Use the power of your cordless drill to clean and scrub (drill not included). This car/boat cleaning kit includes the Drillbrush Original Power Scrubber corner and contour brush in soft white. Use this classic brush to clean car and motorcycle wheels, RVs, Boats, Jet Skis, Jeeps and off-road vehicles. Interior grime, stains and spills are no match for the rotary scrubbing action of The Original Drillbrush Power Scrubber. Included in the kit is a 5 In. flat round brush. Tackle large areas like Tonneau covers, large area carpets, or boat hulls quickly with this larger brush. The 4 In. flat brush is also handy for bigger areas. Do you need to get into tight spaces or hard-to-reach areas – included is a 2 In. diameter brush for all of those hard-to-reach spots like around lug nuts, in between mag wheel spokes, or narrow areas of carpeting.
