Quickly clean narrow wheel openings and slots! It can take as much time to clean your wheels as it takes to wash your entire car. Modern wheels have openings to facilitate brake cooling but cleaning these narrow openings can be a real challenge. Our 11 inch Small Opening Wheel Brush quickly cleans caked-on road grime and brake dust inside smaller, slot or mesh (BBS) style openings. Natural tampico bristles are resistant to acid cleaners yet won't scratch expensive alloy. The bristles on our Small Wheel Brush are 2 inches in diameter. This brush works best with wheel openings of 1 to 2 inches.
