The Philmore 8523B is a 7-inch, plastic, wall-mounted brush that is designed for cleaning switches, terminals, and other electronic components. It has tough, stiff, bristles that make it great for scrubbing away dirt and dust, and the cordless design makes it easy to move and use. The plastic body is rugged, so it can stand up to plenty of use, and it's lightweight, making it easy to maneuver in tight spaces. The angled head allows you to clean small, hard-to-reach areas, and the snap-on cover keeps the bristles protected when not in use.
