I mentioned I use a homemade "Evapo-Rust" type cleaner for rust removal and was asked to explain, so I figured a new topic would be useful for searching in the future.
I first stumbled upon it as a substitute for PCB etching acid, and quickly discovered it worked well at many things. It's roughly 50 water/30 vinegar/20 Hydrogen Peroxide/and enough salt to dissolve. You will need to refresh the hydrogen peroxide occasionally as oxygen will come out of solution.
This really isn't cost effective to be used on large parts, but for small items it works quite well. Leave the item to soak for a few hours, then under running water scrub the rust off with a wire brush. The surface will be left with a matte grey finish that's very easily polished with scotchbrite.
These are the pictures. I picked this drill chuck up at a thrift shop for #1 and am still trying to free it up. The cleaning was all done in the manner written above. I have not cleaned it up with scotchbrite yet.
The wire brush was hard to get into the annular ring gear, but the rust is loose there. Notice how clear and readable the letting is.
I'm trying electrolysis to get into the body of the chuck and free it up. If not, well, it was $1 after all...
