Small Carpet & Tirewall Brush-packed nylon bristles staple-set into a foam block. Bristles are crimped for added strength. Great for cleaning white sidewall tires and for stripping paint for home furniture refinishing.  You can also use this with upholstery and carpet shampoo as it has an extra stiff approach and has an easy-to-use handle as opposed to the carpet and floor mat scrub brush.
