I would guess more likely silver sulfide. Silver actually oxidizes with some difficulty but sulfides fairly easily. Silver sulfide is not very conductive. You are right about sulfide or oxide removers, they tend to remove metallic silver as well. The problem is caused by sulfides and peroxides in the atmosphere. It is a problem in preserving photographs.

The black stuff is likely silver oxide, which is conductive. It can usually be left alone. OTOH the tarnish removers will strip come of the silver that you want to keep.

That oxidation can be polished off with a bit of Tarn-X or other silver
polish. Might be easier dipping it in a *liquid *type of silver polish
first.
