CMT's new non-toxic, non-caustic cleaner gives you more cleaner for your money, and it does more for your cutting tools, too. Unlike other cleaners, CMT 2050 requires no rinsing after it has done its job of loosening even the hardest baked-on encrustations on your saw blades, router bits, shaper cutters, planer knives and other cutting tools. All you do is wipe the tool clean, leaving a thin film coating that protects against rust and corrosion. 2050 may be brushed off with a water rinse, which might be more convenient on high tooth count saw blades.
