    I bought my ultrasonic used and since it was my first ultrasonic I
    wasn't sure it was working.  So while it was running I stuck my
    fingers in it (OK, I don't always approach every problem with logical
    thinking).  No immediate effect but after having my fingers submerged
    10 seconds or so I felt the bones in my fingers and finger joints
    aching so I knew this was not a good thing.  I too clean my fingers
    in my ultrasound, (I use Simple Green -- Thanks Orchid!), but it is
    with the ultrasound turned off.  It's been a few years ago I can't
    say it caused any permanent damage but my exposure was a one time
    experience.  From the aching I felt in my fingers I would guess
    regular exposure to ultrasonics made for cleaning jewelry, dental,
    parts, etc... could cause permanent damage.  No scientific data to
    back up my theory.  Just someone who was dumb enough to see what
    would happen.  And for you Jeff Foxworthy fans it may have proved I'm
    a redneck...  ;-)
