remove rust from melting pot?

[jtmattison]

Does anyone have a good way to remove rust from inside a lee electric lead pot and if so, a good way to keep it from rusting again?
No matter what I do to try to clean it up it is rusty and nasty again in a few days. I leave lead in it to keep condensation from forming and rusting but it doesn't work.

Gee,I assumed they were supposed to rust.Rust is an oxide layer like the browning on a gun.I just scrape the bottom and sides with a spoon with a wood handle,once each casting session,while fluxing the alloy or lead.Then remove the dross and rust with the spoon.Doing this after fluxing helps minimize the loss of expensive tin if you have alloy in the pot.

I thought about a few ways of preventing the rust, but each raised the possibility of lead splatter during a future heating, so I just let it rust and ignore the problem. A replacement is too cheap to risk serious injury.

You'll never be able to prevent a lead pot from rusting. One by product of lead, zinc and copper smelting is sulphur. Sulphuric acid is corrosive. And that is what is rusting your lead pot.
