The Clean sweep helps keep your Bandsaw's tires free from debris which shorten their life and effect blade tracking. As debris; saw dust, metal on metalworking saws, or any other debris accumulates on the tire, continued use without cleaning compresses the tire more in other places then if it were in contact with the rubber or urethane alone. Over time the tire will loose its rebound in those places if not cleaned properly and thus decrease tire life. (Currently only offered for 14" saws)
