Electrolysis Rust Removal

[Eric Estes]

Has anyone ever tried something like this for rust removal on gun parts? Not that I intend to, just curious. Thanks.

I have done this process many times on parts and restored many old cast iron skillets, simple to do and really works quite well.

I know (without truly understanding) this attacks only the rust (assuming no other metals in the tank) and I've seen the vinegar soak method as well. My question is does this have any effect on the case colors? What about the vinegar (acid) method? I understand neither method will affect the molecular hardening, but am not sure about the colors. I'm thinking Parker top levers, S&W hammers, LC Smith side plates, etc. Thanks.

I would also be curious to know what it might do with the iron and steel mix of Damascus.

Vinegar will remove more than just rust. It will attack case colors, bluing and the metal itself.

I didn't try that on antique firearm parts, just no need since I got my old proven way, but it look very inexpensive and what I really like is a capacity to do large parts, and since I restore other items that are way bigger then firearm parts this is something I will be trying right away. Thank you very much!

have no knowledge about electrolysis re guns but I would have a concern about one metal being more effected than the other
