Not really. it's the phosphoric acid in coke that does the trick. If it were carbonic acid, soda water would work just as well-it doesn't. Incidentally weak oxalic acid (as found in rhubarb leaves) works even better because it chelates (binds) the iron. Downside is that it is poisonous so handle with care.
