The Penetrating Oil Used by Pros

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 helps remove and prevent rust, cleans and lubricates, and displaces moisture. NEW!

What is the difference between Kroil Original Penetrant and Kroil Penetrant with Silicone (SiliKroil)?
Both products have similar penetrating properties, and can be used in multiple applications. The biggest difference between the two is the lasting lubricating effect of silicone in Kroil Penetrant with Silicone (SiliKroil). In addition to lubrication, silicone helps to displace moisture, which adds an extra element of protection.
