Powder Blast is a powerful, high pressure solvent gun cleaner that blasts away powder residue, grease and oil build-up, leaving the firearm clean and ready for lubrication. Powder Blast gun cleaner is applicable to all shooters, but especially heavy volume shooters such as law enforcement officers, handgun shooters and clay, trap and skeet shooters. Because Powder Blast is quick and convenient, cleaning is done more often and more effectively. Contains citrus oil and high-pressure, fast acting environmentally safer gun cleaning solvents with CO2 propellant. Citrus oil is an effective oil and grease cutter used in hand cleaners and detergents. Only Powder Blast Gun Cleaner employs this active ingredient to break the bond of old oil, grease and gunpowder residue. Works immediately without disassembly and leaves gunmetal brilliantly clean and free of oil, grease, plastic streaking and gunpowder residues. Works faster, better, safer; environmentally friendlier. Pleasant citrus odor.
