Without seeing the set the general rule is to start with the least abrasive method first and then work your way up. I'd start with a mild cleaning using white (not orange) GoJo hand cleaner and then try an automotive cleaner/wax from Meguiar's or Mothers. Sanding would be my absolute last option and machine buffing has risks of damage or burning to a small cabinet that size.
