Dremel 428 Carbon Steel Brush
A wheel-shaped brush with carbon steel wire bristles 3/4". Ideal for cleaning and removing rust and corrosion from items made of brass, copper or other soft ferrous metals--such as tools, door knobs, automobile parts and electrical contacts. You can also use wire brushes to create an artistic effect on coarse-grained wood. Its shape makes it well suited for cleaning flat surfaces and getting into hard-to-reach places like slots.
