Original Penetrant - Rust Penetrating Lubricant - Corrosion Inhibitor Oil for Chains, Hinges & Stuck Metal Parts - Home & Industrial Use - Can - 1 gal - 1 Pack (KL011)

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+++

This stuff is awesome. It removes any trace of rust, and even used it on some plumbing fixtures that nobody could loosen because of hard water deposits, and did the trick quickly and effortlessly. All around good stuff to have handy for any stuck components, be it automotive, firearms and even plumbing.

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

Good stuff. Give it time to work. It is not instant but a few hours (overnight best) and it will get the job done. Used it for restoring old Springfield percussion cap smooth bore. Worked well freeing up rusted trigger mechanism and removing rust from barrel.

Works like a charm. I couldn't believe it when the rusty bolts broke loose!!

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

This stuff reeks, absolutely a "windows open" kind of oil, but I'll be damned if it doesn't work extremely well. I had stuck bolts that wouldn't be set free even with brake cleaner or WD-40, and this stuff was able to penetrate deep into the threads and knock the offending gunk loose, making my life a breeze. It's a bit pricy for sure, but it beats acetylene in terms of leaving parts intact.

Smells ok ,and works quickly

Great stuff, frees up rusted and seized parts

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.

The only penetrating oil I trust when things are serious and failure not an option. Also it smell nice.

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

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