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).
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.
Watch how a leading commercial HVAC contractor uses Kroil to help keep their clients cool and comfortable.
“If I see a can of Kroil in a shop, I know they know what they’re doing.”
