...found more than a few advised not use sterling/fine silver in
the Ultrasonic Cleaners because it might damage/pit the surface.
Is this true?
I’ve never had it happen. But I imagine if you have more than one
piece in there at a time, and one piece has more mass than another,
it might be possible. The cavitation from the ultrasonic might cause
one to ping against another. An ultrasonic is better to get polish
and other gunk off a piece than using a toothbrush. It will not
remove tarnish. Get a good one that’s made for the jewelry industry.
The versions made for the retail public are a joke.
...Also what about Ionic Cleaners, do these REALLY
work?...considering purchasing an Ultrasonic Cleaner for my studio
to remove dirt, rouge and grease off my pieces.
An ionic cleaner is great for removing tarnish, especially the
insides of chains where it’s impossible to clean tarnish otherwise.
You can’t leave silver in for too long though, or it will redeposit
the tarnish back onto the piece. Let it lift the tarnish to the
surface, brush it a bit with a toothbrush, put it back in for a few
more seconds. Repeat until the tarnish is gone. It will not remove
dirt, rouge and grease. That’s what the ultrasonic is for.
