Muriatic acid (diluted hydrochloric acid) sold for cleaning masonry will
remove zinc plating very quickly. This is a cheap chemical, sold in most
home stores that sell paint and caulk products for masonry.
It's best to do the stripping outdoors, and observe all safety precautions
related to yourself, kids and pets.

If you're using sheets of steel that you want to strip the edges, you could
use a trough made out of PVC or some other heavy plastic material.
If the sheet edge is too long to dip it, you could improvise a way to catch
the run-off and use a plastic squirt/dribble applicator bottle (probably not
a good idea to try to spray it) to strip the edge.

Rinse the stripped area with water after the application. I usually rinse
with water/baking soda solution. If you're not welding immediately, apply a
rust preventive that you can remove quickly before welding.

From time to time I find it desirable to weld something that has been
galvanized. This has required grinding off the zinc.

If I was to get one of those do it yourself zinc plating kits, could I
just
reverse polarity and de-zinc the iron?

About the time I had mastered getting the toothpaste back in the tube,
then
they come up with this striped stuff.
