Well, we do have sandpaper in NC, but something like a dollar bill or a points file works better for cleaning points. The sandpaper/emery cloth can leave little bits embedded in the points which will cause them to eventually fail-permanently.
I have used the dollar bill trick numerous times to freshen up a set of points in an engine that won't spark after sitting for a long time. Try that first. Then a file. Then new points.
Works on voltage regulator contacts too.
