Would RecommendMost of what I work on is rusted up and old whether its my old Silverado or my old BMW motorcycle or the Old Lady's Subaru and Kroil is the best thing I have ever used ,...no other product comes close. That's tough salted up West Virginia rust. I don't trust the tough jobs to anything else.

Kroil lifer
Would RecommendI keep purchasing the 8 oz drip cans to keep in my garage, basement shop, in my truck, and at my job site. Only issue I’ve ever had with it is the little red plastic screw on caps… please, can I get a few?

Nothing works better!
Would RecommendI've been using Kroil products for over 40 years. I have tried numerous other products, including the combination of acetone and transmission fluid I've read about, and nothing works better. I use both the drip can and aerosol for my jobs. The drip can allows me to reduce the amount of Kroil I use and better control where it goes. There is no overspray when using the drip can.

Blow That Horn!
Would RecommendI had a well-used, and neglected trumpet that had set unused so long that the slides … didn’t. The valves were basically useless. Nothing would work … until someone recommended Kroil. I am a happy camper. Thanks!

The only penatrant you'll ever use again!
Twenty-five years ago I purchased my first 8oz. drip can of Kroil penetrating oil. I was working in a race shop, building and supporting air cooled Porsches. Kroil was the only penetrant that would allow us to remove broken head studs and broken exhaust studs. Porsche heads and engine cases are an aluminum alloy and the studs are high grade steel. Besides being loctited in, the dissimilar materials could make removal a frustrating multiple hour job. Kroil and a mapgas torch turned this job into ...

Great features
Would RecommendI have been using Kroil (the oil that creeps) for over 30 years as a Locomotive mechanic. I can say Kroil has yet to fail in doing it's job. Nothing else comes even close. Kroil does what it says it will do. As an added feature Kroil also has superior Di-electric qualities that is absolutely necessary when working high voltage equipment

Started for 1 thing, found many uses.
Would RecommendI've been using Kroil to clean guns for 10 years. Having it around I now use it for my garden tools, loosen rusty bolts om my cars, aids in disassembling plumbing, sharpening, cleaning wet stones, the list seems to be endless.

Steam gaul frozen turbine bolts
Would RecommendWhen you have a steam turbine running for a year under extreme heat conditions and they are absolutely galded together this Aerokroil will have an edge to separate the giant bolts after a few hours of use. I have actually seen it travel upwards on threads of a bolt .

A little lasts. Amazing product.
Would RecommendI bought this a few months back because the guys I work with swear by Kroil for loosening rusty components. It has save d me so much time and money using it on old bolts, locks, and rusty nuts. Just a little goes a long way and lasts a long time.

The Best!
Would RecommendI sold Kroil oil for over 20 years and always recommended Kroil products over other penetrants. My neighbor came over one night and asked if I had anything to free a screw up on a fishing reel he was working on. He said he had tried everything to try to loosen the screw. Told him I had something that would work! Put a little Kroil Oil on the screw and in less than 5 minutes, the screw was loose. He asked where he could get some of that stuff? Told him we sold it where I worked. He came up the ...

You get what you pay for.
Would RecommendI was introduced to Kroil 22 years ago and have not changed my thoughts about it since then. It is the best penetrating oil I have use in my 45 years of being a Machinist/Mechanic.

Kroil and Grandpa Love!
Would RecommendThis is what my Grandpa introduced to me many years ago! Didn’t take much for me to be a believer of Kroil! That old machinery sure would be stubborn till Pop Pop got Kroil out and broke things loose! Even in the military with the tanks, Kroil served proudly! Pop Pop was a believer, Uncle Sam was a believer, and I’m a believer! I keep Kroil handy!
