Electrolysis… its super easy to set up. I tried it a few weeks ago on a plane iron. Works really well and it is not difficult. you need a motorcycle or car battery charger, a plastic bucket, a peice of steel(not galvanized or plated) to collect the rust and washing soda( the stuff that raises the ph for my hot tub worked well sodium carbonate).

fill the bucket half way with water add a few tablespoons of soduim carbonate and stir.
take the part that has to be derusted and hook the negative lead from the charger to it and suspend it in the solution so that it does not make contact with your piece of steel. i used wire and a piece of wood over the bucket. next hook your positive lead to the piece of steel that will collect the rust and drop in the bottom of your bucket. now you can plug in the charger. this process works line of sight so you may have to turn or flip the part you are derusting after a couple hours. I let my stuff soak for 2-3 hours then check it. hit it with a wire brush and the rust comes off super easily.
the one thing to be very careful of is this process supposedly creates hydrogen, so absolutely no flames or sparks anywhere near this solution.

sorry about the lack of punctuation. good luck whichever method you choose.
