Kroil creeps into millionth of an inch spaces, dissolves rust, lubricates and quickly loosens frozen metal parts, frees rusted bolts, frees frozen shafts. Dissolves dried grease and oil, displaces water, without harming metal. Works great for getting underneath and loosening built-up carbon, copper and lead fouling in shotgun, rifle and pistol barrels. When a surface is wet with Kroil, it will not corrode.
