Okay, so there are more than one use for a pig aside from Bacon and BBQ. This Boar's Hair Wheel Brush is so soft and gentle on your wheels, you'll replace other brushes forever! Cleaning wheels requires a little extra stiffness due to the amount of brake dust and road tar deposits. I have no idea why Boars hair is better than Horse hair or butterfly wings for that matter but apparently the Boars Hair has just the right amount of natural stiffness and softness to be perfect for the application. The"split-ends" clean a wheel much better than any other brush. Just a quick shake in water will clean the brush free of brake dust and road grime. With this brush, your hands will stay clean and free from black brake dust. Available in either a 8 1/2" or 20" durable plastic handle. Priced individually
