I had this happen with a batch of IC sockets once. The plating
eventually started coming off the pins! It's enough to make you think
you're losing your mind.

I also have a rare old IC with pins that have turned almost black.
Buffing with a pencil eraser helped but it's still pretty ugly. I
don't dare solder to it in the first place and now I'm wondering if
it will even work in a socket.
Would lots of flux and a solder pot do any good in these situations???
