General Discussion / Re: removing rust from cast iron
« Last post by butt on October 06, 2025, 09:58:04 AM »I have a decorative cast iron 'pagoda' lantern - that I found 10+ years ago, half sunk in the mud of a farm pond - that was caked with rust.
I tried the second method yesterday, but I must have goofed on the citric acid/soda ratio
So.... Put together a 5 gal bucket electrolysis set-up this morning.
Seems to be working...
Will let it run overnight. Will probably take a few days, given the extent of the rust.
Looks exactly like this one I found online:
(Its about 10" T & 7" W, at the base)
