jewely cleaner

Ultrasonic cleaners use high-frequency sound waves (listed examples: 42,000 Hz / 42 kHz) to dislodge grime. Many units offer preset cycle times — example presets shown include 90, 180, 280, 380 and 480 seconds — and a common tank capacity listed is 600 ml (20 oz).

Listings advertise very fast action: examples in the listings show general cleaning in about 30 seconds and removing tarnish in as little as 10 seconds. These are manufacturer claims; actual times can vary by product formulation and the severity of tarnish.

Listings commonly recommend using the degassing function if the unit has one and adding a few drops of liquid dish soap to the water to help break up oils and improve cleaning performance.

Listings commonly name gold, silver/sterling, platinum and diamonds or other precious gemstones as suitable. Some product descriptions also list broader surfaces such as glass, ceramics and other household materials.

Some products list compatibility with gold, platinum, diamonds or generic “precious gemstones,” while others are specified for silver/sterling only. Multiple listings advise against pearls, coral and opal; some ultrasonic notes add emeralds and jade to the not‑suitable list. One silver dip also cautions against painted, plated or antiqued items.
