I found a tray full of tools in the garage that has been filled with water for some months or years from the looks of it. The tools are mortally rusted, but I was wondering if there might be some way to shock life back into them. I was wondering if there was something akin to electroplating that might revive them. My first google search led me to this instructable, and I thought "ok, wow, this really is 'a thing'." and I commenced to setting it up.

Got it all set up, and as I was watching the first tool fizzing in the electrolyte bath, it dawned on me that this is the exact same setup that I used for electro-etching a few years back. As I recall, what is actually going on is that the current super-accelerates the oxidation process. I recalled watching a youtube video where a guy did this very same thing to intentionally add years worth of rust to a metal sculpture overnight, for artistic effect.
So what am I doing here? Fighting rust with rust?
Now doubtful of the process, I decided to continue, but compare the results with an un-eletrolyzed control rusted tool. The instructable says that after electrolyzing the tool, you still need to wire brush it. So, I did, and on another comparably rusted tool I only wire brushed.
here are the results:
Electrolysis pliers, before:
Electrolysis pliers, after:
Non-electrolysis pliers, only one side done for comaprison.
So I think the non-electrolysis pliers actually look better. But they were not the exact same pliers, and may have been in better shape under the rust. I am wondering if I should even continue with this. Does it violate the laws of nature and/or common sense?
If you google "electrolysis rust removal" you'll get tons of hits, describing how to do it and how it "works", but that is not evidence of sound science. You'll get comparable hits if you google how to make a magnetic perpetual motion motor.

I did not even question this at the time, because I was sold on the idea.The current travels through the solution and in the process flakes off the rust - the flaking/softening occurs because of the reaction at the surface of the good steel that pushes the rust off.
