Muriatic (hydrochloric) acid, perchance.

I've heated water beside the fire in a galvanized pail to wash with, but
I've never done any cooking in galvanized pans.  Zinc is fairly reactive
chamically and I dislike reactive metals in cooking.

Some friends who worked at a wire plant and the galvanizing pit say to avoid
the fumes and don't fall in.  The melting point of zinc is 419.4 degrees F.
