Pamona ban jacks - solder won't stick

<<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.>>

I've found that sanding with a light grade sandpaper will get through the 
plating or corrosion & allow solder to stick to even the crappiest cheap 
Radio Shack jacks.
