The Magnasonic ultrasonic cleaner uses high-frequency sound waves to scrub jewelry at the microscopic level: fill the 20-ounce stainless steel tank with tap water and a drop of dish soap, set one of five preset cycles on the digital timer, and the cavitation bubbles shake loose the skin oil, lotion, and grit that build up in ring settings and chain links. It handles rings, earrings, necklaces, watch bands, eyeglasses, and coins without chemicals or brushing, and the before-and-after on a years-worn engagement ring is the whole reason this thing went viral. Best fit: daily ring wearers, glasses wearers, and watch collectors with metal bracelets.

Frequently asked questions
What can I safely clean in it?
Diamonds, sapphires, gold, platinum, stainless steel, eyeglasses, watch bracelets, and coins are all fine. Skip pearls, opals, emeralds, and anything glued rather than set.
Do I need special cleaning solution?
No. Warm tap water with a single drop of dish soap is what most owners use. Dedicated solutions exist but are optional.
Can I put my whole watch in?
Only if the watch is properly water resistant, and even then most owners remove the bracelet and clean it alone. Water can reach the movement through worn seals.
How long does a cleaning cycle take?
The five preset cycles range from about 90 seconds to several minutes. Heavily grimed pieces may need two runs.
