We used to pour Coca Cola on rusty wheel rims and watch it
eat
away the
rust. This was when I was very young, but you could give
it a
try
to see if it works.

I can't vouch for this method, but there is some reasonable
chemistry behind it. Coca Cola contains phosphoric acid
(like
Naval Jelly) which can reduce the rust, and carbonic acid
which
can 'boil' the rust out of tight places.

Imagine what it does for your teeth. Especially since the
bacteria
in your mouth can metabolize sugar into lactic acid.

Why? Is lactic acid useful for removing tool rust?
