Utah Mike, I am unfamiliar with electrolysis being used to remove rust [from barrels] etc. Can you explain a bit ?
Daryl,
I could never write it up as well as many folks on the internet have already done.
https://www.google.com/search?q=electrolysis+rust+removal&ie=utf-8&oe=utf-8I use it often as it DOES NOT disturb any original finish that remains, only the "loose" and surface rust.
Recently I used the process on a rusty pre-Civil War Starr revolver and found a surprising amount of original bluing still remained.
One caution. Between the process and the soda water solution, the surface will be completely devoid of rust AND oil. If you don't dry and oil the surface immediately, it will flash rust. Most of that can be wiped off with an oily rag, but it defeats the purpose if you just let it rust again.
