Looking Good

We’ve given our packaging a swell new look, but the products you love haven’t changed a bit. (New packaging coming Summer 2021.)

Loosen Up

When rusted and corroded metal parts slow you down, trust the very best penetrant to loosen things up. Proven since 1939, nothing is more effective than Kroil Original Penetrant, available in liquid and aerosol (formerly AeroKroil).

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.
