What's the best way to clean the contacts of an open-frame TR relay?

I still use a little burnishing tool that's been in my toolbox since my days as a young guy driving around Chicago fixing sound systems. It's a strip about 3 inches long by 3/8 inches wide with a green handle and somewhat abrasive metallic compound. Pulled it out the other day to clean the contacts on my paddle.
