Clenzoil® Field and Range™ Foaming Aerosol is a high quality, one-step cleaner, lubricant, protectant and rust inhibitor for Lock, Stock, and Barrel™. It effectively removes oils, copper, lead, and other contaminants. It provides a thin, non-greasy coating that prevents rust and lubricates all moving parts of firearms and sporting equipment. Clenzoil® will not harm polymers or other synthetic surfaces. This proprietary foaming aerosol does not use flammable or moisture laden propellants. The unique dual-purpose vortex spray head can apply a consistent surface coating when sprayed from a distance of 4-6". When applied from a distance of 2" or less, the product will foam into a thick lather that will work its way into small hard to reach areas, lifting and separating grime and other contaminants from the surface. Not recommended for painted surfaces.
