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

Have heard about this magical elixir for years. Old school mechanics from New England to the deserts of Nevada have pointed to the orange can and said their tales of how it loosened the impossible where others had failed. - I was always too cheap to try it. So, here I am decades later and watching one of my favorite YouTube channels and there it is, the orange can. “it’s a bit pricey, but worth it “ as he gingerly applied it on a rust solid fitting. Moments later, it worked. Not a sponsored product, just a guy showing how simple and effective it is. Facing a glass mounted frozen wiper arm fitting on a place that can’t be cut, warmed, drilled or muscled, I ordered. Finally. The oil smells wonderful, btw. A few drops over three days, and the corroded grip was dissolved and the arm freed. No broken glass. No cussing. No drama. Okay, the oil works great, I was ridiculous not trying it earlier. I’m actually mad at myself because it would have likely saved a ton of time and broken parts over the years. I’ve used it since and am exceptionally pleased with it. Thanks to all who recommended it. Price wise? Same price as two cans of what doesn’t work. A+++

Yes, it is crazy expensive. 3-5x the price of the competition. NOT well known. No advertising. Limited availability. But wow. This stuff really works. The hype is real. The drip cap is quirky; don't break it. Used just a few drops on some very heavily rusted parts that had been sitting for 20 years. A few minutes later, they came apart easily. Count me impressed. This 8-ounce can is probably a lifetime supply for most homeowners. Cannot believe this has been around for 80+ years. If you need something that may or may not work and have a thin wallet, buy one of the many choices at the big box store. If you have expensive parts that absolutely need to come apart, pay the price. You will not be disappointed

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.

Kroil is the best,hands down

Very good product. Very minor leakage in the box in was sent in but didn’t soak to the outside of the box. One of the very best penetrating oils made.

Love this for my firearms. Price is high for what it is

Oh I heard of this many years ago just started using it and wow it works like nothing I've ever tried before. It cleans carbon and creeps into hard to get spots like magic. Funny smell but works amazing

Terrific!

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

Magical stuff. Easily kills of rust and helps removal of rusty bolts and nuts and screws.

It worked great on the frozen element on the hot water heater. I put some on a day or two before the impact bit arrived. It wouldn't budge before, tightened it to crack it loose, then it spun off like magic. Really penetrates through anything. Be careful getting it on your hands or face, it has a really strong smell and may cause skin irritation...i was careless, i could smell it for two days!
