Best Penetrating Oil Used by the Pros
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, and pulleys. 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.

Good Stuff!
I sprayed Kroil on a rusted nut, let it set a few minutes, and the nut backed itself off
My Go To Can.
I have used Kroil for well over 30 years. It is the best. Period. BTW, I always called it Kroil.

best penetrating oil I have used
This is worth the money for any tough job

First time user of Kroil. This stuff works!
Purchased Kroil ahead of a planned exhaust gasket replacement on a 1998 C3500 1-ton truck. I knew the exhaust manifold bolts were crusty with rust before I started the project. I sprayed on Kroil.. grabbed some lunch, then returned to my project and the exhaust flange nuts came off without much effort. I plan to keep a can around the shop in the future.
