|The two cleaners are very different and wire artists usually use the ionic and bench jewelers usually use the ultrasonic. Keep in mind if your customers gemstone has a unseen crack in it and you clean it and break it you might own it!
That's why I like the Ionic cleaner best and there fairly reasonable as compared to an ultrasonic cleaner. Here is a info on both:
Ionic: Cleaning and polishing in one easy step. The IONIC system uses polishing agents and gentle soap cleansers to remove tarnish and dirt with a safe bubbling action. These bubbles are formed by the carefully-controlled electrical current that passes through metals reducing surface tension of dirt and floating it and tarnish away - instantly. Restores metal luster and stone brilliance.
Ultrasonic: Water or cleaning solution is poured into the tank. Then the jewelry such into a tray and the tray goes into the tub. The motor on the cleaner runs and produces ultrasonic waves. The energy waves create small bubbles and these bubbles surround the jewelry and collide with the surface of the jewelry and knock dirt and grime off and the dirt settles to the bottom of the tub.
They are very pricey over $300 for a good one. I have had poor luck with the $39.95 type they don't work well enough for any type of jewelry business even a small one.
