Hanging Loose Since 1939

Our Story

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.
