So many of today's wheel designs are beautiful to look at but a nightmare to clean. Especially the back side of a wheel which is usually painted the wheel color and difficult to access. This tool is made from a soft yet porous synthetic material that will grab grime and lift it off the wheel. Its wedge shape allows you to get into small areas. The handle is comfortable and molded to fit your fingers. The standard brush is 9 3/4" long, and the Long Reach is 12 1/4" long in case you have wide wheels. Great for motorcycle cleaning too.
