KG-12 provides shooters with a product which will remove the toughest of copper fouling without harming any other metal.  Unlike other etching, ammonia based cleaners; KG-12 will not damage the metal of the bore. There is no need to "neutralize" KG-12 as is required or recommended with other ammonia based products and no need to "get it out quick" like ammonia based enchants.  KG-12 is water based and contains no ammonia and no synthetics.
