Ultrasonic Jewelry Cleaner 49KHz 650mL

The 3M ultrasonic jewelry cleaner uses 49,000Hz high-frequency sound waves to clean eyeglasses, jewellery, watch straps, dentures and small accessories. A 650mL 304 stainless steel tank holds multiple items at once. Five digital timer modes run for 3, 6, 9, 12 or 15 minutes. The unit measures 8.2042 cm by 13.3096 cm by 23.2918 cm and includes four anti-slip rubber feet for stability.

Who This Suits and Who Should Look Elsewhere

Ideal for personal daily cleaning of glasses, earrings, braces, makeup brushes and watch bands without scratching. The 22oz capacity handles several pieces per cycle. Not suited for buyers who need larger-volume tanks for bulk or commercial workloads, or for anyone requiring heated ultrasonic cycles, degas functions or multi-frequency operation.

Bundled Accessories and Their Impact

The package supplies the cleaner, a power adapter, a user manual and an eyeglass cloth. The adapter enables immediate mains operation. The cloth provides a lint-free finish after the ultrasonic cycle. No cleaning solution is included, so users must supply their own fluid or run water-only cycles.

Questions about this item

Does the 49 kHz ultrasonic cleaner need any extra solution to start cleaning?

No, the machine runs with plain water; adding the optional ultrasonic cleaning agent is only recommended for tougher grime.

Will the 650 mL stainless‑steel tank hold my existing watch straps and eyeglasses together?

Yes, the 650 mL capacity fits multiple straps, glasses and small items at once, so older pieces can be cleaned in the same cycle.

How can I confirm the 49 kHz cleaner is running correctly after I press start?

The digital timer counts down through the chosen 3, 6, 9, 12 or 15‑minute mode and the unit emits a steady ultrasonic hum while operating.
