as jeep owners rust is a big part of our life.
any of you chem dudes (not the snort chem dudes) ever heard of this rust removal process.
might be an old wife's tail, but i know sometimes working on an old vehicle, you need to save the part as there just are not any other replacement parts out there.
"> I use molasses in solution, 5 parts water to 1 part molasses, although I've seen folks go as high as 10 to 1. Immerse the rusted part in this goo and forget about it for a while. It's not fast; surface rust might take a week, while deep rust might go 2 or 3 weeks. But I don't have to come up with a safe way to dispose of nasty chemicals, either. My well is no further than a couple hundred feet from my septic system, so anything I pour into the ground has a shot at working its way into my drinking water. Normally, we store the nasties until the town has a hazmat disposal day, typically once a year.
> Molasses contains something called a chelating agent, the chemistry behind which I don't claim to understand. It binds to the iron oxide, but it won't attack the rest of the metal that isn't oxidized. This process, like the others, won't make metal grow back, so if the surface was deeply pitted, it will come out deeply pitted, but a very rust-free deeply pitted. The surface will be clean, bare metal, so when you pull your parts out, be prepared to paint them, oil them, or come up with some kind of protective coating, or they'll oxidize very quickly again, sometimes in minutes if the conditions are right.
> I've got a small vat of this going in my basement right now with a number of tools soaking in it, and more in the waits.
