Kroil Aerokroil Penetrant - Rust Penetrating Lubricant - Corrosion Inhibitor Oil for Chains, Hinges & Stuck Metal Parts - Home & Industrial Use - Aerosol - 16.5 oz - 4 Pack (AZKS162C4)

This stuf is awesome! Works better than anything else I have tryed. The with or without silicone should be a bit more visible

Great product. Does what it says.

This is the BEST penetrating oil I have ever used! It gets rusty bolts free faster than any other penetrating oil I've used. They have me as a loyal customer. Especially because I only need to use a little bit unlike others where you have to drowned the bolt so I use less and which makes it less messy and each can lasts longer. Great value! I didn't want to buy it because of the price but now its the only thing I use because of how well it works!

Great product,cost a little more than the other brands,but worth it.

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!

People swear by this oil, that it penetrates better than other solvents. That might be the case; I think it works as good as PB Blaster, without the nasty chemicals. (It seems less nasty than PBB.) The nozzle is well-attached and directs the solvent; and you can give it a tap to deliver just a tiny amount, which offers good control. The oil is a bit thicker than PBB and is able to set there and settle in. Good value. One bottle will last a while; but why not buy two?

This is the best penetrant and protectant there is out there maybe a little pricey, but well worth it

Works great for rusted fasteners

I'm not a big fan of this cans spraying system... Too much flow under too much pressure but that's a personal thing and i found a way around it... With that being said, the contents inside are fantastic and i won't buy anything else.

I've tried a lot of stuff in the past, but this is the best for extremely rusted nuts and bolts. This is the only stuff I'll buy from now on.

I had a particularly difficult union to remove with severe corrosion on it. Tried well known penetrants but they did not work, so cleaned them off with a solvent cleaner and applies AeroKroil. After three days of reapplying it, the union was able to be removed. Brilliant product!

Expensive but works second to none, you definitely get what you pay for.

Used my 'normal' penetrating oil on a seized bottom bracket on an old Halfords steel bike. Put the bottom bracket in a vice and turned the frame, absolutely no joy. Bought some of this, a squirt a day over 4 days, then the same vice technique and it came loose first time. Expensive but worth it for an amazing penetrating oil.
