Versatile brush for removing rust and corrosion, and polishing metal surfaces. Deburr and blend surface junctures, clean electrical components. Pack includes two carbon steel brush accessories. Use on items made of brass, copper, gold or other soft ferrous metals-such as tools, door knobs, automobile parts and electrical contacts. 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.
