Thanks, Jim. I was hoping someone had actually tried it. I've got a
relatively expensive casting I want to derust, and it was either the
vinegar solution or beadblasting to remove the stuff.

Or -- electrolytic rust removal.

I've used both to good advantage. Honestly the
electrolytic method does have an edge over the
salt/vinegar approach, as the residue left behind
is a bit less troublesome. Though it is somewhat
more trouble as it requires a power supply, etc.
