Kroil Original Penetrant - Rust Penetrating Lubricant - Corrosion Inhibitor Oil for Chains, Hinges & Stuck Metal Parts - Home & Industrial Use - Drip Can - 8 oz - 4 Pack (AZKL081C4)

Best penetrating oil on the market by far! I've been using it since the 1960s when it was only available to industry. I'm glad it's readily available to all of us today. It really does lossen frozen fasteners in cars, boat engines, motorcycles, farm equipment, ect. I also works as a firearms bore cleaner when mixed into bore cleaning solvents (25% Kroil/75% Bore solvent.) The Kroil "creeps under metal fouling in the barrel rifling loosing it for easy removal. Kroil is just "Good Stuff"

My dad had a can from the time I was small, it was great, the new stuff looks different but seems to work even better. This stuff is great. After spending weeks on a stuck screw, tried everything to no avail. In one night of this the screw came out easly.

I’ve used a lot of penetrating oils over the years, but Kroil Original really does live up to the legend. I’ve been using it on your run-of-the-mill rusted nuts and bolts, and it works like magic. A few drops, a little patience, and things that should’ve snapped loose years ago finally start moving again. They say Kroil is made by squeezing leprechauns - and after seeing how it creeps into threads and breaks loose rust, I’m starting to believe it. The drip can make it easy to apply precisely where you need it, without wasting half the can in overspray like aerosols. It’s not cheap, but a little goes a long way. If you’re working on anything that’s been sitting in the elements - old cars, farm gear, or just corroded fasteners - this stuff is worth every penny.

Best penetrating oil. I needed to replantih my supply.

I’ve been using Kroil Original Penetrating Oil for a while now, and I can honestly say it’s one of the best penetrating oils I’ve ever used! Whether I’m working on rusted bolts, stuck machinery parts, or even old tools that have been sitting unused for years, this product gets the job done quickly and efficiently. The penetration power of Kroil is unmatched. It seeps into the tiniest cracks and breaks down even the toughest rust and corrosion. In many cases, I’ve been able to loosen parts that I thought were impossible to get unstuck, saving me time and frustration. It works fast, and you don’t have to wait long before you see results. The application is easy, and the spray nozzle gives a controlled, fine mist that ensures the oil gets into the tightest spots without waste. I appreciate how it doesn’t leave a greasy residue after use, making cleanup a breeze.

A little pricey but works fine

Kroil in its original form. Oil yes. You squirt it or drip it from this easy application can. Best value for the money form. This form lasts longer than aerosol spray. It drips out no noise.

Great oil for stuck bolts and for wiping guns after cleaning.

This stuff is a life saver when trying to in-stick rusted screws and other metal parts. Used this on several old firearms and haven't messed up a single screw since I've had this. A couple drops and wait a few minutes and you are probably good. Creeps into tight crevices and through rust. This can be expensive to get in Canada but if you have a stuck screw that seems impossible, stop and give this stuff a try. It will save you from having to order new screws more than likely. Smells interesting like cherries and gasoline but now I actually kind of like the smell.

Price is little high comparing with same in market , Smell is very strong

This is simply the best penetrating oil I have come across. Simply magic stuff

Great product and arrived on time.

Je l'utilise pour enlever le (carbon ring) dans les carabines et ça fonctionne très bien.
