I don't know what is called but where can I buy one of these little black plastic socket thingies?
Please dont tell people to use products containing salt to clean copper. I dont know how this got started.
Anything acidic like vinegar will clean the copper. Salt will accererate oxidation and produce that lovely green patina also known as Retsyn.
Simply scuff the copper contacts lightly with scotch-bright pad.
