I had the dremel out for another project but just polished some NOS pins with the polishing bit (felt) and some compound. I can reach the outside but to get the insides, I'd have to trim felt and put some time into this. Will there be a reward for such activity? The outsides went from really tarnished to original surface. It's a contact surface I'd say small gain??
Cleaning tube pins
Anyone have any suggestions for cleaning gold plated tube pins on NOS tubes. I have heard that Caig's is not the answer. Plus, I do not want to take the chance of removing the gold plating.
