How to remove rust?
Answers: Rust is Iron Oxide.
Some of the iron on the surface of your tin have been chemically converted to iron oxide.
That rust hence contains some of the iron which was once your tin.
However you try to remove the rust, if you succeed consequently you will therefore also hold removed some of the iron which was once your tin.
The surface of your tin may next be rust-free, but you cannot expect it to look as if it was nice and smooth and shiny and tentative, because some of the surface has presently been removed.
At best you can repeatedly remove (wire brush, wire wool etc), but the surface will be pitted due to loss of the iron things.
You cannot put that back.
There again, this pitted appearance may furnish character to your tin.
P.S. I do not recommend chemical rust removers, as they never live up to their claims of making flakes of rust rear legs into new metal. Also they can lastingly stain the surface.
How rusty? Try vinegar.If that doesn't try dilute pool acid
use alcohol
lick it past its sell-by date .. it tastes nice too!
I'd try a damp brillo pad. Rub, wipe, repeat- until rust is gone. The brillo wipe is abrasive, so try removing rust from a small invisible spot first to see if you want to do it to the rest of the old tin.
