A lubricating and penetrating oil that flows into the tiniest of crevices, lifts away lead and copper jacket fouling, frees up super-tight barrels, loosens frozen screws and bolts. 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.

Closest thing to magic in a can
Closest thing to magic in a can. We had an old .22 receiver in the shop that no one could get the screws out of, it turned into a strength contest. One day, an old man came in and asked if he could have the receiver if he got the screws loose. Boss said yes and guy poured Kroil on receiver and said he’d be back in about half hour. 30 minutes later he removed the screws liked they were only finger tight. Been using Kroil ever since on anything rusted.
