Clean small parts and in tight, hard-to-reach spaces with the toothbrush-sized 3-pc. Mini Wire Brush Set. Three different bristle materials cover a wide variety of surfaces and applications. Nylon bristles are easy on finished surfaces making them ideal for sweeping away dirt and debris from around interior door panels, trim pieces, dashboards, and crevices where panels meet. Soft brass bristles clean unfinished metal parts like screw threads, connection terminals, and cutting tools without damaging surfaces or fine features. Stiff and aggressive, stainless steel bristles deliver scrubbing power for removing loose paint, scale, and rust from metal parts. Comfortable and easy to hold, the finger grip polymer handles offer sure control, even with wet hands.
