Do any of you know why they use silver as the contact metal in relays? Because silver oxide IS A CONDUCTOR ! That is also why it is used as a plating on the pins of loctal tubes. If you scrape them, you defeat that silver plating by scraping it away. BE CAREFUL cleaning them. More common is a bad socket which needs cleaning since they didn't plate the contacts on the tube SOCKETS.
