Thanks. I was taught to use an ink eraser to clean contacts. The Army tool
kits for telephone and Teletype repairmen included contact burnishers. The
school concentrated on electronics, ciphony and Modems, and slighted the
mechanical components.

I was using "burnish" in a general sense. It's really hard to get
anything inside those switch shells to clean up the contact area. So
maybe a Q-tip with something on it, bit of cloth held in a hemostat...
you have to improvise with something depending on how bad they look to
be🤷

I have several different erasers, they work pretty good if they can
reach the problem area🙂
