That's right, just like WhiteLion, this really kicked off in fifteen minutes:

Sorry these pictures aren't as great, but I assure you, the rust was really flying off...






Thrilled by my results in such a short timeframe, I shut the whole process down, made a clean solution and removed the oxidation from the copper pipe (positive side).

I fired it back up and decided to let it run all night (about six and a half hours)...

Turns out, I've copper plated a good portion of the blade where all the rust has come off.




So, yeah, it seems that perhaps using copper as the sacrificial anode (scrap metal piece) may not provide the desired results. The rust removal was fantastic and the blade really does look a lot better. Certainly a lot smoother, although there is some apparent pitting. Even if I hadn't plated it, it would need fresh solution, a good anode cleaning and probably another night.

After work tonight I'm going to find a different piece of scrap to use, some sort of steel/carbon steel and toss the whole thing back in to cook.

Questions or comment, lemme know, otherwise I'll put up more tomorrow.
