Original Penetrant - Rust Penetrating Lubricant - Corrosion Inhibitor Oil for Chains, Hinges & Stuck Metal Parts - Home & Industrial Use - Drip Can - 8 oz - 12 Pack (AZKL081C12)

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"

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.

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.

helped remove a rusted, stripped screw when WD-40 did not do it for a change.

Best penetrating oil. I needed to replantih my supply.

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.

Good idea to own. Use sparingly. Clean area first before use (wire brush metal and a solvent rinse). No reason to overuse KROIL. In concert with 50/50 Acetone/Synthetic ATF it’s a one-two punch to go after corroded fittings/fasteners.

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.

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

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

This is the best penetrating oil I know. Works wonders. Be advised that it has a very strong smell.
