KROILOriginal Penetrating Oil (Aerosol Spray-16.5oz Can-Single) | Penetrant for Rusted Bolts, Metal, Hinges, Chains, Moving Parts | Rust, Corrosion Inhibitor (KS162)

Penetrates great , pricey but worth it.

I encountered a rusted mower blade that was firmly attached to the machine despite my efforts to loosen it using various twisting techniques. Despite having tried penetrating oils available at my disposal, none of them proved effective. However, after reading positive reviews about Kroil, I decided to give it a try. To my astonishment, I allowed it to soak for approximately an hour, and the rusted blade came off effortlessly. This product is truly remarkable. While it may be priced higher than some alternatives, its effectiveness far outweighs its cost. I highly recommend trying Kroil, as you will undoubtedly be satisfied with the results.

Aerokroil, or Kroil, is 100% the best penetrating oil, there is no comparison! We’ve all used WD, and it has uses, and many of us have used and loved PB, but Kroil is in another class all together! First time I used it was when trading in an old truck and I couldn’t unlock my hitch pin, even with PB (which I swore by at the time), the dealer grabbed his can and gave the locking hitch pin a couple quick shots and then said “give it a minute”. After a brief pause I tried my key again and it instantly turned like new! He gave me the can and related his experience with it and praise for it. Since that day, probably 7yrs ago, I’ve used AeroKroil (aerosol version) and a wide variety of tasks and have seen it seemingly work miracles! One example would be my use of it on dead bearings, I work on conveyors amd so deal with a lot of rollers which eventually freeze up from rust. I’ve had 100% dead rollers, ones that I couldn’t turn even a little with a long pipe wrench, restored to absolutely free spin with application of this penetrating oil. I just spray a bit on the end by the earring and let it soak in for a bit then I give it a turn, there’s usually a millimeter of resistance but I’m able to easily further bearing past that and then I give them a good spin by hand and they are back to functioning perfectly!Just this past week my father called and told me that the can I gave him fixed a neglected yard aerator that he borrowed from a neighbor. He said it had been unused for years and that when he got it the wheels with the tines were all frozen together as one (they are supposed to turn independently) and that the axle itself was hard to turn. He remembered the can I gave him and how good I said it was and decided to try it. Sprayed the wheels and the axle then let it soak for a while and then was easily able to break them loose from their rusted grave and that now this old weathered and unmaintained piece of equipment worked as good as new! He said he was impressed and was happy to not only be able to use it the aerator but also to give it back in vastly better condition than it was in when he borrowed it!Cheaper oils have their place, but when something is absolutely stuck or rusted or even just noisy or not smooth enough what you need is Kroil! They made me a fan and I’ve regularly carry cans of AeroKroil along with some of their other products such SiliKroil and Penephite. FYI SiliKroil is Kroil plus silicone and works great for applications where the oiled parts will be exposed to water such as the carrier slides on the equipment I run. Penephite is Kroil and graphite, it’s great for things where you’d use graphite such as internal metal on metal parts that are not easily accessed and have no built in means of lubrication, it’s extremely useful for oiling locks and I use it on my houses exterior doors as well as automotive door locks. …back to the product at hand, AeroKroil (Kroil), it is simply the finest penetrating oil I know of and if you try it it will become your preferred oil whether it’s for use around the house or on multimillion dollar equipment!

Call me old school, but this is an old time favorite from when they made things that work and STILL DOES! Kind of like the old Bryell Cream adds- ( am I dating myself?) - a dab will do you. No need to use half a can soaking a nut down. Just enough to get it wet give it a few minutes to work, and will come loose. What more can you say - works better than any thing else. They call it the "oil that crawls" . that is probably a good description.

Greatest oil ever!

It is expensive for a reason. The best rust buster liquid out there hands down. I use it to clean rust off my tools that get exposed to weather and moisture a lot. It disintegrates the rust and I wipe it off. There is no wire wheel or brush needed. It also breaks bolts free every time I have used this stuff. Like always proper preventative maintenance goes a long way. get the silicone added spray from Kroil too I use it to prevent rust.

Excellent stuff. Stinks, but works. “Squirt a little cat pee on it!”

Works very well on metal knitting machines
