I picked up a 2gal English pot recently. Standard electrolysis wouldn't do too much for the inside; since, it is more of a line-of-sight de-rusting method. Here is the setup I came up with:
1ft rebar clamped into the red charger lead, tied to a 2X4 stud w/ twine
7qts standard electro solution (even though the pot is marked 2gal)
20amp charger borrowed from the electro tank
and a 5gal bucket of deck stain for ease of use to help set the height of the red clamp on the charger. Yes, it is the same bucket of deck stain I still need to empty in order to clean the #8 favorite waffle iron with wooden handles I picked up a year ago, but I'm working on it!
I cleaned off one of the handles on the pot, and that is where I attached the black charger lead.
Amperage was rather low, but after 12hr, I was surprised by how much oxidation was removed. I'll finish the outside now in the electro tank.
