    Since a lot of people are writing in about meshes of various
    materials, I thought we might do well to note Ken Kotoski's comment
    in his most helpful paper of notes on ultrasonic cleaners: 

    "Anything you put into the ultrasonic that is not a rigid solid (for
    example plastic or rubber) will greatly reduce the cleaning ability.
    That is why glass beakers and steel trays and baskets are used.They
    pass the ultrasonic wave right on thru without impeding them. Wire
    mesh baskets are not as good as solid pans or beakers.20 The mesh
    actually breaks the waves up into smaller waves and these smaller
    waves are weaker and don't clean as well as if a solid bottom pan or
    beaker were used." 

    I'm afraid the link I have to the article seems to be for a now
    unavailable page.
