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,

they come up with this striped stuff.

Phosphoric acid is milder than muriatic acid and will remove zinc if left to
soak. The fumes don't seem to rust everything in sight either. Look for
Jasco Metal Prep products at Home Depot.
