    Richard, I find that I can use a tweezers to hold the item in the
    ultrasonic for 20 seconds to get it clean after buffing. If the
    liquid in the ultrasonic cleaner has been used alot it is my theory
    that little particles of buffing compound or whatever are thrown up
    agaist the item being cleaned and mar the surface so unless I have
    pristine liquid in the cleaner I don't leave the items in very long. Annette
