Kroil Oil
When it comes to freeing corroded items in tough spaces, nothing rivals powerful, industry-proven Kroil penetrating oil. Used and trusted by pros and experienced DIYers alike 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.

Why Kroil Oil & Lubricants?
We’ve been around long enough to see a few things, and the world has certainly changed over the years. But regardless of how things have evolved, three constants remain: metal rusts, parts lock up, knuckles get scraped. To solve these universal challenges, we established the Kroil brand in 1939 with the goal of producing the very best penetrants on the market. Since then, our Original and Silicone formulas have been getting hard-working folks out of tightly locked situations in just about every industry…and quite a few home scenarios as well.
What is the difference between Kroil Original Penetrant and Kroil Penetrant with Silicone (formerly 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 (formerly known as SiliKroil). In addition to lubrication, silicone helps to displace moisture, which adds an extra element of protection.
