C K 45 works great on industrial machines, business machines, motor shafts, guns, sports equipment, shop tools, saws, drills, electric motors, vending machines, locks, hinges, roller bearings, conveyors, pulleys, nuts, bolts, and all rusted corroded parts. C K 45 is fortified with friction-reducing substances designed to rapidly penetrate and loosen frozen parts caused by heavy wear, grease, or grime build-up. Its micron-sized particles of PTFE lay down a protective mesh film like hundreds of tiny ball bearings working side by side to dramatically reduce friction, prevent corrosion, and prolong the life of machinery. C K 45 is also effective over a wide temperature range and does not contain 1,1,1, Trichlorethane.
