“Had a bolt stuck on an outboard motor that had years of heavy use in saltwater. After throwing every other penetrating oil on it (and failing), I found Kroil. Literally one application and the bolt was out!”

My Father was a machinist and used Aerokroil. So when I started in the HVAC trade and needed penetrant I reached for Kroil!

“We deal with a lot of situations where heat has frozen all bolts, particularly on hot box core jobs and heat treat ovens. Before Kroil, it was burn ‘em off and drill ‘em out. Now, we have a high rate of success with just Kroil and a hand impact wrench.”

Kroil is our go-to penetrant. It definitely helps make our jobs go smoother.

I was 5 years old and my Grampa was working on Grams car. She had a flat tire and was stuck in traffic in Boston on a one way street. I remember it was after school and there was a lot of traffic and people were getting angry there was a lot of yelling and shouting. It was very scary and my Grams started to cry. Gramps came and started to change the tire. It started to rain and I could see him getting frustrated. He went back to the trunk because the lug nut wouldn’t come off. He had this orange can and sprayed it on the frozen lug nut. Honestly it broke the rust free. He changed the tire and Gramma left and traffic started to move. As I have grown older and learned it was KROIL, I never bought another product. I tell my friends and family even coworkers about how well it works! Great stuff would highly recommend it.
