Italian Gun Grease Copper Eliminator, part of the IGG system for advance cleaning, protection, and performance for handguns, rifles, and shotguns, dissolves embedded copper and lead in minutes without causing pitting or eroding the metal of the firearm. It works quickly to eliminate build-up with the application of the cleaner on a gun patch. The non-toxic, non-offensive proprietary formula is developed and made in America to work in tandem with another IGG product, the Carbon Eliminator. Available in three convenient sizes: 2 ounces, 4 ounces, and 6 ounces.
