"Penetrating" Oil

What is this stuff? What makes it more penetrating than any other low viscosity oil? Maybe some solvent/surfactant added to aid the oil's ingress?

I'm thinking about threaded fasteners that get power-washed. Like spoke nipples in a motorcycle wheel.

It's what resembles to me anyhow, a thin grade of kerosene. Kerosene works almost as well, is cheaper.

When I was a kid in the 60's, my father put Liquid Wrench in rusted stuck nuts and bolts and wait overnight. It never seemed to help me. A couple months ago I unscrewed the barrels off a couple dozen rifles that fought in WWII. I would put the barrel in the barrel vice, the action in the action wrench, and hit the action wrench with a 20 pound hammer. When it would not move with 5 or 10 hits, I would put 5 drops of Kroil in the crack and wait 10 seconds. The barrels always came loose with the next hit.

All the guys I demonstrated this to went out and bought some Kroil.

I don't know what's in it, but I've had the same experience with PB Blaster on frozen marine parts. It was the only thing short of dynamite that would take a shaft coupling half off the prop shaft in one of my boats, that hadn't been disturbed in 20 years. Another guy at the yard turned me on to it, when he heard me cussing in the bilge. A good overnight soaking and the coupling half was off with a couple swats of the hammer.

Nothing but a light petroleum distillate. In short, boob bait for bubbas, like most of what's on that aisle with the pretty bottles of stuff to pour into your engine/transmission/stuck-bolts/radiator/etc to fix expensive problems as if by magic. Check the MSDS if you don't believe. I confess to still having a can on the shelf from my ignorant youth.

Kind of like selling ordinary glue with "weld" in the product name. You suggest what would be illegal to claim, and the casual or the simple will buy.

What is that physics theory that a belief in something can affect the real world? Therefore if I believe in Kroil, (I do, I do, I do believe,) it's use does result in the loosening of previously impossible to remove fasteners.

Nothing like the smell of "Kroil" in the morning !! The best stuff on earth for almost anything that moves, slides, rusts, etc. A "must" for every tinkerer. I bought some of their products 15-20 years ago and they send me mail every 2-3 months. A great small company. I also use their Memogenda (low cost, high value version of a Franklin Planner). I have an amazing story on Kroil too. Bolts were froze on my exhaust system, sprayed Kroil, waited 10 minutes and they came right out. Great company with excellent products......

Yeah, it's good stuff and works as advertised. The airline I work for sure believes in it and there's one gallon cans of it all around the flight line and hangar.

I dunno. I had some hydraulic hose connections which had probably been together for 35 years - Kroil - nothing. Heat, more Kroil, nothing. Repeat. I eventually found connections at either end beyond where I needed to open it up that would move, got the entire assembly out, was able to put 3-foot cheaters on the wrenches, and then they came free just fine. No room under the tractor for 3 foot cheaters.

I also have tried it on a power steering cylinder anchor pin, with no results. Shortly I'll try it again (having given it several months to soak in), and I expect I'll end up burning the pin out (that's what the dealer recommends).

IIRC, somone here claimed that you could make your own, cheaper, by mixing ATF and a solvent. Not quite the same mix as Ed's Red (another fine ATF-based recipe).

I know a sewing machine guy that has a "homemade brew". He uses ATF and alcohol. I don't know the ratio or type of alcohol (isopropol, ethyl,denatured,etc.).
