I tried the vinegar bath and it certainly does work.  I used Heinz distilled
white vinegar.  But, I did have a couple of pieces that I inadvertantly left
soaking over the weekend.  It's quite pitted, but not ruined.  Actually the
effect was sort of interesting.

To All, 
It is the phosphoric acid in Coke that does the rust removal. Lemon juice
works too.

Disolved CO2 in the coca cola results in a mild acid called carbonic acid.
At least until the coke is flat it would contribute.
