someone told me that I can strip zinc in a plastic tub filled

I know vinegar has lots of uses, but is this so?

Try it with a penny?

Copper coated zinc? Copper left over?

I'm confused......

looks like I left out something in my post. grrr, hate that when
that happens.

Its for a steel plate that is zinc plated or any steel that has
been galvanized.

Vinegar will etch the galvanized coating, but I seriously doubt
it'll "strip" it. Not strong enough. (Well, maybe if you leave it
in for like two weeks or something.)

vinegar really works!

OK, I stand (well, sit) corrected.

I know vinegar is really good at cleaning metal. When I work on old
things (e.g., cameras) with schmutzed or hazed brass or chrome parts, I
throw them (the parts, not the camera) into a vinegar bath. Brightens
'em right up.
