    Does anyone know if those Ultrasonic cleaners really work.
    It's the type which uses a small stainless steel bath(and water) and high
    frequency vibrations.

    I have one but can't see any difference when I take the "cleaned" things

    Tried adding a few drops of dishwashing liquid to the water but doesn't
    make any noticeable difference.

    Thanks for any advice.

    I have made LCD glasses using such a bath, but to
    clean things properly, I used
    1. acetone.
    2. diluted alcohol
    3. pure alcohol.
    4. isopropyl alcohol(100%).

    Each stage for a few minutes.
    The reason for all the different fluids is
    that you need different solvents for all sorts of
    Using soap water is a bad idea, because that leaves
    a monomolecular layer of soapmolecules on the surface.
    And that very quickly degraded the LCD cell.
    Oh and I used a motor with a ?vacuumsucker?? to centrifuge
    the glass dry, to get a minimum of residu layer.
    So yes, those baths are usefull.

    Yes they do.

    Try suspending a strip of aluminium cooking foil in it. The ultrasonic
    agitation abrades the surface and should make holes in it after a minute or

    Maybe your cleaner is crap or broken.
  4. Is it working? Things get dropped into them and the ceramic comes
    partially unstuck, they still make the right sort of buzzing noise

    The manual said to add a few drops of washing liquid to help the cleaning
    so was only following orders.
    Makes sense that different dirts needs different solvents to assist in

    It's only a cheap($100) hobby version but can't see why it wouldn't work
    if not damaged.

    Saw a show last week where an electronics manufacturer used one for cleaning
    various boards etc... so assume there must be some truth in their operation.

    Thanks again, Boozo.(am actually a tea-totaller).
