Thread: OT-Any uncommon uses for an ultrasonic cleaner?

"...cleaning your wife's jewelry..."

What? Naaa... there are several types of jewels that should never be immersed in a US cleaner.

Emeralds - it is legal for manufacturers of such jewelry to use "Jeweler's Oil" to enhance the beauty. The oil fills in the tiny fisures. Placing emeralds in a US cleaner will both remove the oil, thus making the emerald look cloudy, and just might increase or complete the fisures resulting in a small pile of expensive green dust.

Pearls - The US cleaning action will remove the layers of pearl material until you end up with the tiny grain of sand that started it all.

Moonstones - ditto

Opals - the US cleaner's action can shatter the stone right along all the fisures that provide the reflections.

So if you have a US cleaner, be very, very careful. Do some research before trying to clean milady's treasures. You just might be able to avoid a week or three in the dog house.

I did a relocation print for a large 3-tank unit (4' x 4' x 4' tanks), Blackstone up in nearby Jamestown, N.Y.
makes them.

I had to provide 50 kw of 575 vac to the thing ! Granted there are some big heaters in it,
but the panel and amplifiers where quite large.

It also ran some 14ph nasty stuff, would take off cured epoxy.

Does anyone hear the things ? I do, they seem to scream much like white noise.

This post has been much appreciated, learned something new today.
(like good thing I never dipped my finger in that vat....)

Not surprisingly they work great for golf club heads too.

Let me know if you want to get rid of the big one Howard, I may be in the market for one.

Thanks,

They do a remarkably good job cleaning my shop running shoes. They always get coolant and oil on them and then the dirt sticks and the next thing you know you look one step closer to the homeless person at the intersection begging for change. I use the heater in the tank and a tiny bit of dish soap and the old Crest makes the shoes look almost like new again. A couple of hours in the sun to dry and I am not embarrassed to wear them to lunch or the post office.
