When the worth of your jewelry pieces runs in the thousands of dollars, you'd want to take care of them properly. The care or your jewelry pieces will depend on what metals and gemstones they are made of. One easy way to clean and polish your valuables it by using ultrasonic jewelry cleaners.
How does an ultrasonic jewelry cleaner does its job? It's pretty much the same as brushing off dirt, but instead of a brush, vibration from ultrasonic waves knocks off dirt and stains off your jewelry.
The vibrating motion of the ultrasonic waves creates microscopic bubbles in the water or cleaning solution in a process called cavitation; millions of tiny bubbles knock into one another and into the items resting in the cleaning tank. The cavitation process gently knocks dirt off the jewelry. The motion is very effective at penetrating the tiny crevices in jewelry that traditional cleaning cloths and topical cleaners cannot easily reach.
Because this method uses cleaning solutions that usually consist of non-ionic surfactants, detergents or ammonia, this cleaning method may not be suitable for all types of jewelry. For example, your John Hardy silver pieces can be restored to their original gleam using an ultrasonic cleaners, but your opals, pearls, emeralds and other soft stones are better off with more gentle polishing methods.
