Butch,
The tiny pieces of grit from emory cloth or sandpaper tends to become embedded
in the contact material, and disrupts the pattern of spark when the
contacts are
closing or opening, leading to premature burning of the contact.
A small metal file is the way to go.
At least that's what I was told several years ago.
