I am unfamiliar with the use of electrolysis but dont know how it could possibly clean the inside bowl area any better than it already is.
Hi Don,
Well, it wouldn't necessarily end up "cleaner", but it could possibly get rid of those areas of splotchy discoloration. No guarantee, but it might. Electrolysis is a complicated process..I don't understand it all, I just know that it turns red or oxidized iron into black iron. If you're interested, here is a link explaining it better than I can.
http://www.woodcentral.com/cgi-bin/readarticle.pl?dir=handtools&file=articles_363.shtml The problem with this piece, is after electrolysis, (inside the bowl), you can't season it properly ..which could further make any remaining splotchiness disappear..without destroying the label. I get that the label sets this piece apart from a fairly common skillet, and wasn't advocating you remove it, but I can still see rust on the outside and bottom, as well as some whitish streaks of something on the sides. That is another reason I said it could be better. Maybe those weren't the final results and you've done more since those pics were taken. If you have, maybe you could submit a couple more pics of your end results. But rust should be dealt with or it could end up as Perry said, a nice label on a now de-valued rusty skillet.
Anyway, you might someday acquire a piece with no label that has rust. If you want to see what electrolysis can do, here is a fairly recent thread by a member..on her first attempt at it. The pics speak for themselves. ;)
