The Kinetronics Anti-Static Brushes are the optimal solution for dust removal in various fields of technology, optics, and craftsmanship. They effectively remove dust from expensive lenses without risking scratches that could damage the coating. Kinetronics Anti-Static Brushes are made from a blend of natural and synthetic fibers, permanently housed in a handle made of conductive plastic. When dirty, the brushes can be washed with a mild shampoo. After washing, the fibers should be combed and left to dry overnight on a flat surface. The antistatic properties of the brushes are not affected by the cleaning process. The brushes are 20 mm wide.
