There is nothing more frustrating than a stuck lock in your front door or car. But, with 3-IN-ONE® Lock Dry Lube, you can unstuck locks quickly and easily, without any mess. Our lock lubricant formula is safe to use on metal, wood, and most plastic surfaces, and the attachable straw fits easily into narrow lock mechanisms. This lock lubricant goes on clear and dries to the touch within minutes so it won’t attract dirt that can gunk up inside. Plus, there is no gray residue to clean like other graphite lock lubricant formulas.
