I seem to recall someone mentioning a way to clean relay contacts by applying
voltage ? Looking for a way to try to clean up some sealed relays in a 2x6

60 years ago, not long out of EE school, I had a job driving around
Chicago fixing audio and video systems. One of the most used tool in my
box was a "contact burnishing tool." It's a thin strip of metal with
both sides finely abrasive. I still have two of them.
To clean contacts on my paddle, I've used a piece of paper.
