Kroil Original Penetrating Oil (Liquid-1 Gallon Can-Single) | Penetrant for Rusted Bolts, Metal, Hinges, Chains, Moving Parts | Rust, Corrosion Inhibitor (KL011)

I have had great success with Kroil products, both in liquid form and aerosol. I've used it extensively on turbine engines, and stubborn automotive components. Sometimes WD-40 works to loosen rusted or corroded parts, but Kroil products seem to penetrate deep into threads and tight tolerances more effectively. I love Kroil products.

I bought the baby and then I bought another. It wasn’t long after that I was out again and needed more, I bought more baby cans and a spray can, then bought my first big can which has led to several other purchases of multiple big cans! Kroil lubes, frees, relieves, protects, and does all kinds of things that will impress you as it has me around the house and at work as well. With tools and tooling, drilling, trailers and hinges, on the farm it’s irreplaceable, garage it’s irreplaceable, workshop it’s irreplaceable. If it’s stuck, here you go, the man who has everything, give him some of this!!put that WD and PB to bed, Kroil on in and thank me later!

I used KROIL for years in the Army, and it was great for our needs then, now instead of automotive uses, it is a great solvent for cleaning guns! It won't harm polymer, wood, nor finished on firearms, and if you don't get it all cleaned out before applying your favorite lube, no worries, it is oil.Now, I just need to figure out how to pour it from the 1 gal container into smaller containers w/o spilling so much (yes I used a funnel).

This is the absolute best penetrating oil I've ever used in my over 45 years of working on antique vehicles. A few drops and a few minutes and nuts almost take themselves off.

This is a must have in the garage!

Penetrates thoroughly into rusted threads and etc.

This stuff is an amazing miracle, plain & simple. Soaked rusted pliers overnight and they work again! I’ve recommended to several family and friends. One gallon will last my lifetime.
