a business card and contact cleaner without oil will work for most dirt too.
use a dry card for final polish. if very pitted a point file will get you a
smooth surface again, however if the surface is just plated it will remove
the plating. Replacing the relay is the only fix for plated relay contacts.

Me, if a relay goes flaky I would replace it
In terms of very fine abrasives, the stuff used to polish the ends of
optical fiber is as slick as it gets. It is a polyester film coated with
diamond dust

I have had good luck with a ladies Sapphire fingernail file, very fine
