I'm wondering why the salt. It surely does nothing but perhaps cause
problems later on.

See your friendly local chemistry professor :-).

Do you not know what it does?
I've got a fairly reasonable handle on chemistry, and I can't see what
the salt is there for. The acetic acid will dissolve rust, and slowly
dissolve iron. No need for the salt unless you know of a good reason.
Please expound.
