I know some of you are aware of this because I've seen it referenced in a few threads, but I thought I would post a thread with my experience.
Removing rust with molasses. Google it, you'll find lots of references.
Heres a
nice YouTube video.
I've done this for a few years. I have a big vat ( a Rubbermaid storage container ) filled with a 10-1 mixture that sits under my workbench.
I've put all sorts of things in there, nut&bolts, engine/frame parts, chrome parts. They come out clean clean clean. My earlier experiments were with the absolute worst rusty old car parts I could find. I was amazed.
Now, this removes rust, it does not "make metal". So severely corroded parts will come out clean, but pock marked where the rust was eating deep into the surface. But the task at hand was "rust removal", so that's what you get.
The trick people neglect is t...i...m...e... I've soaked parts for up to 4 months. It literally is "set and forget" (literally, I've forgotten about things I've put in there when I switch projects). I've never encountered a time period where "too much time" damages whatever part I put in there. That time may exist, I'm just saying *I've* never encountered it.
A friend of mine soaked the inside of a KZ1000 tank for a few months and it came out shiny clean.
Of course, for small quick jobs I use EvapoRust. Great stuff, same principle. But you'd never afford a vat of that stuff
