KROIL 8 Oz. Original Penetrant Oil

I was recommend Kroil Oil Penetrant by a gun smith. The best penetrant you can get. Can't be beaten because of it's multiple uses. Not only can it not be beat for loosening rusty bolts but works great for removing built up carbon in my hunting and match rifles. I'll never be at a rifle match and not have a full can with me on my cleaning cradle. I always know once my competitors see how great a job it does cleaning my rifle they are going to want to try it. Next questions from them is where can I buy some. Don't forget for you home mechanics to keep a can handy. It'll surely make your home and auto jobs easier.

Im.working on a relic- a 1948 Willys CJ-2A. It's currently in many pieces thanks to Kroil. It's the best penetrant I've used, hands down. A little bit of heat, a Kroil soak and those 70 year old rusted bolts come loose! Amazing stuff!

Very satisfied with how well it breaks down rust and works into stuck parts and it lasts quite a while if used sparingly.

I’ve used Kroil in industrial applications for years and have a can at home. By far the best penetrating oil Ever! Thanks

Simply one of the best penetrating solutions out there! I have used for most of my 41+ years as an aircraft mechanic. I discovered with my work on aircraft and it was so effective I purchased my own for use at home for use on all my stubborn hardware on engines, utility trailers, lawnmowers, and so much more. I even use it to simply keep hardware that I am not working on, to have a coating of Kroil to keep the parts serviceable and of course, should I need to disassemble it, its less challenging since it has been treated. Keep up with the great products and I will continue to recommend it to others, as I always have!

I got a can of the spray penetrate and never had I found anything to compare to. This stuff by far supercides anything on the market. I will always have a can or two on hand. The best product by far. I have no pictures but I will next time on a project.

I’m not a mechanic, but if idont have a can of this in my garage I get nervous! I don’t care who you are, if you do light maintenance of mowers, motorcycles, or any thing that requires taken apart this is what I use. As I told a buddy, if there’s rust, this is a must!

Prevents rust and easily removes rust. Also works great as a lubricant.

I learned of Kroil penitent years ago when I was working in factory maintenance. I restore old cars in my spare time and Kroil has been an invaluable tool in my arsenal of rust warfare. I would highly recommend Kroil to anyone wanting to break loose rusty bolts and avoid the hassle of drilling and retapping bolt holes.

I first used Kroil in the steel mills (Bethlehem) the mechanical dept. I have a 1931 Ford Roadster that I have used Kroil numerous times. A can of Kroil comes in handy working on firearms, fishing reels, boat motors and even the family washing machine. It works!

The penatrating oil is really good , i would recommend this product for stubborn screws and nuts

Does wonders on old sized suspension parts, that refused to budge previously despite soaking for days in other penetrating oils

I’ve been using Kroil since I started working on cars back in high school @ Boys’ Tech High School - 1975

I’ve been using this product for years. They’ve been a trading oil I’ve ever used.

No broken studs anymore, a couple drops a little time and bingo it all comes loose.

Best stuff there is to release stuck nuts and bolts

My dad worked as a millwright for many years primarily in power plants and paper mills. He came across this product from a salesman in the 1970’s and brought a sample can home. We couldn’t believe how well this worked in freeing rusted bolts. Our biggest test was on an old Continental Red Seal welding engine that had severely rusted and seized exhaust manifold bolts. They had rusted badly, the engine had been left outside for years and the manifold was cracked. We decided to coat the bolt heads with Kroil and come back in the morning. To our surprise the bolts came free without drilling! My dad and I have used this for years after it became available to the public. I tell all my friends about this and they become amazed too. am never without a can of Kroil, Aero-Kroil or Sili-Kroil!!!

The best penetrant on the market PERIOD it’s the only that I’ll use

Nothing is better than kroil oil penitent. And it smells good too!

I’ve been using Kroil since I started work in a glass plant In 1978. My particular job was to maintain a 3000 degree glass furnace. When the burner tips would burn out we had to unscrew them and replace. Kroil was all we used to do this. Been using it ever since.
