[Amps] Ham sells fine grit thing to clean contacts

[Chris Miller]

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
