Updated On: 8th July, Views: I have also had reasonable results with turps and oil, mixed to a watery liquid. Stinks for about two months though. I'm old enough to know better, but I still expected to turn that rusted nut with my fingers after two days of soaking.

Like I said, this product has been recommended by others whom I respect, both on the forum and in my day-to-day experience. I'm sure this product has some uses, but freeing rusted fasteners is not one of them. I'm wondering how they get away with their blatant advertising to the contrary.

I suspect the reasons for its popularity are the same as for other urban legends, and have very little basis in reality. Getting back to freeing rusted nuts, I realize that anything as badly rusted as, say, header bolts, have to be cut off. But my wheelbarrow nuts weren't really that bad. If I could have gotten a good grip on the head, I probably could have just muscled them out.

Being carriage bolts, this was hard to do. Iron oxide, aka rust, is a very hard, fine abrasive. Rusted joints do not actually weld, but are locked in a matrix of very fine abrasive.

Plain old rust, FeO3, is not waterproof, so I suspect any lightweight lubricant, or even water, would penetrate the rusted joint given enough time. But then what? A wet matrix of very dense abrasive particles isn't likely to be any easier to break than a dry one. Experience seems to confirm this. A long shot, but always worth a try. Many mill handles do not, but are well finished so they spin in your hand effortlessly.

Bridgeport comes to mind. If they are supposed to swivel, I'd suggest first washing the parts well to remove all the oil you've been adding, oil that will do nothing to loosen rust, although it would provide lubrication if you had some motion, hopefully preventing galling. Once you have removed the oil, I'd heat with a torch until the handles were quite warm.

If you can heat the rust hot enough, it generally will break down. Heating may discolor the hand wheels, but they can be hand polished with Scotch-brite pads after you have them working freely.

In order to get rusted items working again, you must address the rust, which slowly grows until you have a "press fit". All the oil in the world won't change that.

Do remember that when items rust, they also get smaller, so your fit, when clean, will be sloppy. Brake fluid used to be made of alcohol and castor oil. If it still is, alcohol is a solvent, and probably dissolves the rust to some degree, so that may indeed free up rusted items. Many manufacturers one of which is John Deere tell you to not use gasoline with alcohol in its makeup, most likely for that reason.

Certain components are slowly dissolved, such as carburetors. Good luck with the handles! The oil is supposed to get in and let them slide over each other and so break loose. The penetrating oil gets soaked into places water etc won't "wet" due to surface tension issues. The failure is that most such things as we want to get apart are already a close fit, and the rust has no room to move, so it holds tight anyhow.

The stuff still works Ok on tight fits threatening to gall. How long does it take penetrating oil to work? Can I use wd40 as penetrating oil? Which is better wd40 or PB Blaster?
