The brush is usually made from a large number of steel wire bristles. The  steel  used is  generally a  high

carbon variety and very hard. Other wire brushes feature bristles made from brass or stainless steel, depen-

ding on application.

    Wires  in a wire brush can be held together by epoxy, staples, or in some cases one continuous wire. Some

types of wire brushes can also be used on an angle grinder or electric drill.

• The wire brush is primarily an abrasive implement, used for cleaning rust and removing paint.

• It is also used to clean surfaces and to create a better conductive area for attaching electrical connectio-

        ns, such as those between car battery posts and their connectors, should they accumulate a build-up  of

        grime and dirt.

• When cleaning stainless steel, it is advisable to use a stainless steel bristle wire brush, as a plain carbon

        steel brush can contaminate the stainless steel and cause rust spots to appear.

• Brass bristle brushes  are used on softer surfaces  or in potentially flammable  environments where non-

        sparking tools are required.

• Wire  brushes  are also used to clean the teeth of large animals, such as  crocodiles and pigs. They are

        also used widely in surface engineering to clean the castings to paint the castings.
