Hi Roberta,
While I've never used one for artefact washing, I did use one when I
was
working at a jewellery workshop to remove rouge polish and general
grime
(from rings, etc). The trick was to put roughly equal amounts of
ammonia
and dishwashing detergent in the water and use a toothbrush or
similar to
gently scrub any excess off after the pieces had been sitting in the
ultrasonic for a couple of minutes. You would have to know the way
ammonia
and dishwashing detergent would have on the artefacts, it works just
as well
on jewellery without the ultrasonic though (ie, just with a
toothbrush).
Was there some reason the artefacts needed to be cleaned with an
ultrasonic
as opposed to any other way?
Hope this helps
