When it comes to freeing corroded items in tough spaces, nothing rivals powerful, industry-proven Kroil penetrating oil. Used and trusted by professionals since 1939, Kroil quickly loosens rusted nuts and bolts, frees frozen shafts, pulleys, and more. No space is too tight to reach, thanks to Kroil's ability to penetrate the smallest opening, thread or crevice. Corrosion meets its match, as Kroil removes and prevents rust, cleans and lubricates, and displaces moisture.
STORAGE CAUTION
Kroil penetrant is a petroleum-based product and must be stored in either a metal container or a container made of HPDE plastic only (High-density polyethylene). Long-term storage of Kroil in a non-HDPE plastic container will eventually erode or weaken the plastic. It will also erode any rubber sealing rings included in a plastic dispenser or container. It is allowable to use an incompatible container for dispensing, but any remaining Kroil should be returned to it’s steel container for storage. Our SB32OZ Spray Bottle is manufactured of safe-to-use HDPE plastic.
