We have an old stainless steel jacketed tank we bought some time ago that has some rust in it. We're hoping to use it as the base of a pot still. I've tried Bar Keeper's Friend, and a rust removing gel and both have helped but I still can't remove all the rust. The photo shows the bottom of the pot.
First, any other ideas on removing the rust?
Second, is it usable? What would happen it we ran it with the rust in it?
Thanks,
Ron
