Acetic acid is a weak acid and an organic compound and as such is not corrosive and therefore is acceptable to be used in food in the form of vinegar whereas hydrochloric acid is a strong mineral acid (partially derived from rock salt) and it is corrosive and from the author's experience it can be used in dilute form ie 10% by volume to react with limestone as a diagnostic test for that rock type (the limestone fizzes upon reaction with the dilute HCL.
