Loosen Up
When rusted and corroded metal parts slow you down, trust Kroil to loosen things up. Proven and trusted by professionals since 1939, Kroil Original Penetrant is available in liquid and aerosol (formerly AeroKroil) formats.
Hey Slick
The best gets even better in Kroil Penetrant with Silicone (formerly SiliKroil). Blending Silicone with the legendary Kroil formula results in superior penetration, lubrication and rust prevention.
“If I see a can of Kroil in a shop, I know they know what they’re doing.”
“Kroil has been the most impressive penetrating oil…I would never not have Kroil on hand for the toughest jobs.”
