Yes.I've used it on some woodwork tools, worked great. I'm looking to use it on several other items. I've read where some feel electrolysis causes hydrogen embrittlement. Does, but when does it become a problem? I've also read where some are worried about the hydrogen given off by the process building up to explosive consentrations ... I don't see it unless someone is intentionally consentrating the gas. Another thing I've seen discussed is use of stainless anode. I hear the stainless will break down into some toxic substance. Current is directly related to not only surface area but to washing soda consentration. I couldn't figure out why my power supply kept overloading till I realized I refreshed with too stout of a solution.
The proper polarity is most important. The anode deteriorates quickly, you don't want to part being derusted plugged into the POS.

I've done a few parts so far. I'm satisfied with the results. My parts took longer than an hour like described, but the rust does come off. What crud was left over, I hit with the drill/wire wheel and it's clean bare metal.30 years of rust gone in half a day isn't too bad. It's cheap too.

I'll stick to a Muriatic Acid Dip for steel parts..no pot metal, Rusty..From Mass. 66 motor mount brackets. Had them in straight Muriatic for an hour and they were brand new. Water rinse, spray with Ospho, leave them in sun for a few hours, quick steel wool, prime with Metal Etch Primer, let sit for hour, spray with black, small piece gets natural paint and they're concours ready!
