Just cleaned my table saw extension wings by electrolytic derusting with
spectacular results.

But, I used galvanized ducts for metal plates so I am wondering if the
zinc produced a toxic mixture that I should not dump carelessly. I read
that stainless steel produces toxic waste, so what about galvanized?

I can't say about the toxic nature of galvanizing but isn't there a
certain
amount of lead involved?

Nope. Galvanizing = tin.

Nope. Galvanizing -- _Zinc_
