Open and Shut is a high-performance penetrating oil, non-flammable per ASTM D-3065-1 flame extension test, that cleans, lubricates, protects, and displaces water. There is no better penetrating oil on the market today for working in damp, dirty, greasy conditions, or near ignition sources. Open and Shut penetrates easily through water, rust and grime to provide lubrication to loosen nuts and bolts.
