Cleaning your firearm just got a whole lot easier and faster thanks to Birchwood Casey's Gun Scrubber Firearm Cleaner. Individual 5" x 8" cloths are impregnated with Gun Scrubber and sealed in a foil packet for compact carrying. While safe for firearm usage, the solvent may harm finished surfaces, plastics, laminates, composites, rubber grips or other materials used in the construction of today's firearms. Always test in an inconspicuous area to ensure product will not harm surfaces.
