Are these facts about water & coke true?

**Well, yes, but you are better off visiting a pool shop and buying
phosphoric acid. Phosphoric acid is used to clean salt water
chlorination elements. It works very well to shift calcium deposits.

Phosphoric acid is the main ingredient in rust remover too.
It converts iron oxides to iron phosphates, which are relatively
stable, paintable and pale (not red). I still wouldn't use Coke
for that.
