Interesting. For those wondering, Coca-Cola contains phosphoric acid,
which works well for a rust converter, converting the iron oxide into
something else :-) . You would probably be better off, however, using
just plain phosphoric acid (or diluted, or however it's sold). I guess
it would work for the above, never thought about using Coke though :-)
Probably cheaper to use regular phosphoric acid, though.
