How very unscientific. You can't call a result positive unless you test also for a negative result of the control experiment. So, instead of
performing also a control experiment, you jumped to conclusions without any evidence whatsoever. Indications are not evidence, they do just what the
word means: indicate. An indication can never become evidence unless coupled with at least one opposite indication. Please, learn the basics of the
scientific method.
…there is a human touch of the cultist “believer” in every theorist that he must struggle against as being
unworthy of the scientist. Some of the greatest men of science have publicly repudiated a theory which earlier they hotly defended. In this lies their
scientific temper, not in the scientific defense of the theory. - Weston La Barre (Ghost Dance, 1972)

this is Necromancy for this old thread but I was asked this question recently about how pennies get cleaned faster combining vinegar and salt
.. maybe the NaCl is just a catalyst but I think the problem is the dissociation constant of HCl
.. HCl, HBr, HI, HNO3, HClO3, HClO4 are the strong acids and always completely dissociate in solution .. so forming a strong acid with a weak one is
next to impossible in solution since the dissociation is irreversible
.. hydronium and chloride ions will not reunite inside the water solution to form HCl acid under normal conditions .. so you will not get Hydrochloric
.. to prove it you just need distillation and use the boiling points of HCl and Acetic

This so garbled. 
A mixture of a weak acid and the salt of a strong acid simply behaves like the solution of a weak acid, period.
Weaker acids cannot displace stronger ones from their salts.
Forget about distillation: the HCl-water azeotrope (at 20.2 % HCl) boils at 108.6 C: you'd be distilling off weak acetic acid, nothing more.

Thanks for the confirmation Bloggy
.. there is quite a few Google results that say it forms the acid .. disappointing
