Hi,

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?

Thanks,

Aaron

I can't say about the toxic nature of galvanizing but isn't there a certain
amount of lead involved? I would like to suggest that you dry your table
extremely well (in an oven would be good) and give it some kind of
moisture-proof coating to help prevent the return of the rust. I did
electrolytic reduction of a heavily-encrusted boat anchor many years ago
using a stainless rod and it was spectacular, like you said. I rinsed it in
boiling water three times, dried it in an oven, and coated it with lacquer
as directed in a musem conservation book. After several years it has
developed a small amount of rust.

Nope. Galvanizing = tin.

Aaron: next time try to use steel or iron for the anode. They say that's
what you're s'pozed to use, although sometimes it's hard to find
something the right size and shape in that material.

No idea, I usually just use scrap steel parts... but glad to hear
that it worked out OK for you. I ASSume that you oiled them
immediately...?

Nope. Galvanizing -- _Zinc_

According to this site lead and other metals are sometimes added to the
"galvanizing pot."

During the cleaning process the current flow is reversed from plating
so I dont think it would mater too much what you used for an
electrode. Some old water pipe should work fine.
