Recommended Use
Suitable for most jewelry metals (gold, silver, platinum) and hard gemstones (e.g., diamonds, rubies, sapphires, amethyst, citrine). Note that ultrasonics do not remove tarnish.
Do Not Ultrasonically Clean
- Soft/porous stones: emerald, opal, turquoise, pearls, amber, ivory
- Stones with many inclusions or fractures; heat/shock-sensitive materials
- Complete watches submerged in the tank—immerse bracelets only using a holder, keeping the watch head above solution
Operating & Care Guidelines
- Most cleaning occurs in the first 30 seconds; avoid continuous unattended operation.
-
Use a basket: never place items directly on the tank bottom (risk of transducer damage and voided warranty).
- Maintain solution level between 3/4 and 7/8 full; top off as needed.
- Use a non-ammoniated, non-flammable ultrasonic solution; pre-mix concentrates with water before filling the tank.
- Warm baths clean better; run the unit a few minutes to degass new solution before cleaning.
Solution Savings Tip
At start of day, decant the clear top layer of settled solution for reuse, strain the bottom for debris (check for valuables), dispose responsibly, then return the saved solution to the tank and top off with fresh pre-mixed solution.
