Notes
- Do not place items directly on the tank bottom—always use a basket or rack.
- For most jewelry soils, 95% of cleaning occurs in approximately 30 seconds; avoid prolonged runs on delicate items.
- Generally safe for gold, silver, platinum, diamonds, rubies, sapphires, amethyst, and citrine.
-
Do not ultrasonically clean emeralds, opals, turquoise, pearls, amber, ivory, or other porous, soft, or heavily included stones.
- Ultrasonics do not remove tarnish.
- Do not submerge watch heads; clean metal bands with a holder suspended above the water line.
- Operate with the tank at least 3/4 full; warm, pre-mixed non-ammoniated, non-flammable solution performs best.
- Degas by running the unit for a few minutes before cleaning for maximum cavitation.
- Decant settled solution each morning to reuse the clean upper layer; screen the dregs for valuables and dispose responsibly.
