There are proper tools for burnt contacts....its not an emery board or sandpaper...its called a burnishing file....and they are very fine and seem almost smooth. Not many people outside of my line of work even know what those are.
You can find them at electronics supply houses.

If there was any Silver Plating on my Window Switches it was burned through years ago.
Also a Flat Contact Cleaning Tool is not going to get inside of the Switch.
The Switches have been working at least 2 years now since I scraped them with a Pocket Knife.
In my younger days People used to use a Points File or Flex Stones (a flexible abrasive strip) on the Contact "Points" on their Cars.
I have also used sharpening Stones for knives where there was room to fit them in once the Points were out of the Distributor.
