Best on the market.
Been using Kroil for years. Was introduced to kroil in high school on a part time job on a farm. Once I graduated tech school and started my job in the Industrial Maintenance field I turned the maintenance department into Kroil users. Out with the WD and in with the Kroil. Now I’m an Industrial Maintenance Instructor at a Tech College still advocating for Kroil. The oil that creeps.

Loosens stuck bolts, when others fail
I have a very old can of Kroil, I have found it to be the best for creeping in and loosening stuck bolts ! Just spray it on and leave it overnight.

Awesome product
Absolutely the best product on the market. It is expensive but after seeing what all it does and how amazing it works I will continue to buy it everytime over pb blaster or wd40. KROIL is superior to the other brands
