The Little EZ Detail Brush is small enough to clean between brake calipers and the wheel, grilles, engine bays, and motorcycles. This brush has a reinforced vinyl coated flexible step, and knuckle guards. The 2.5 inch diameter of the bristles are wide enough to clean larger wheels, yet these incredible bristles can flatten against the stem to clean between the wheel's barrel and brake caliper. The bristles are made of a nylon nylex blend that will stand up to the most caustic wheel cleaners. These bristles will regain their shape after thousands of uses. This brush was made to safely clean all types of wheel finishes, including polishes chrome, aluminum, anodized, painted, and clear coated. This is an excellent choice for professionals and enthusiasts.  13 inches long. Made in USA
