This is an old thread, but....
I have a few comments from a chemistry perspective. There was a question in this thread regarding substituting oxy-clean for the peroxide. That won't work because oxy-clean is sodium percarbonate, which is a basic (not acidic) compound. Mixing it with vinegar will neutralize the vinegar, probably not what you want for removing rust. It would be good for neutralizing residual acid on your de-rusted parts though.
Also, the suggestion of mixing peroxide with muriatic (hydrochloric) acid is dangerous. I worked in a chem lab and was investigating different peroxide mixtures to etch some very refactory materials, and tried mixing the two. Within seconds the mixture started releasing bubbles of chlorine gas!! Hydrogen peroxide is a very powerful oxidizing agent, in this case reacting with the hydrogen in the HCl molecule and releasing the chlorine as a gas. Of course, I did the experiment under a fume hood.
While I used concentrated hydrochloric acid and 30% hydrogen peroxide (neither one is commonly available), that result was enough to halt any further experiments along those lines. I write this, having worked with some really nasty chemicals (including red fuming nitric acid and concentrated hydrofluoric acid) over the years with NO injuries. PPE's are your friend when it comes to chemicals.
Just because you can buy OTC chemicals doesn't mean you can mix them willy-nilly. Do some online searching before picking up the mixing spoon.
