Ultrasonic dental scaler for cleaning

I just bought an ultrasonic dental scaler on Ebay. Has anyone tried
this for cleaning? I have had problems cleaning some cast pieces
where there are hard to reach places with traces of investment
material left. Previously I tried a Masterblaster, ultrasonic jewelry
cleaner, toothbrush with various abrasives, etc etc., with
dissapointing results. I was at the dentist and they use this
ultrasonic scaler to clean your teeth. I managed to snag one off of
Ebay for only $50! I hope it works…Anyone tried this yet? I would
think this would be be great for cleaning wax models, cast pieces,
or other stubborn jobs.

Soak your newly cast pieces in water with vinegar before you clean
them.

At the risk of sounding like a 4-yr old… I ask: why?

a dentist who is a friend of mine gave me a cavitron that went
through the flood following hurricane Katrina. since he couldn’t use
it on patients i happily accepted it to water blast jewelry
clean…works great particularly if you hook it up to a source of
heated water, or standard plumbing mixture of hot and cold…if you
got it for 50$ you made a great deal…
