Frequently Asked Questions

Q: What batteries does the portable ultrasonic cleaner use, and how long do they last?

A: The cleaner is battery-powered for maximum portability. Battery type and runtime can vary depending on usage, but the 14W efficient motor ensures effective cleaning cycles without draining power quickly. Please refer to the included instruction manual for specific battery requirements.

Q: Is the 440ml ultrasonic cleaner safe for all types of jewelry?

A: The 304 stainless steel tank and 45,000–47,000 Hz frequency are gentle enough for most hard jewelry including gold, silver, platinum, and diamond pieces. We recommend avoiding use with soft stones (e.g. pearls, opals, emeralds) or items with loose settings. Always check your item's care guidelines first.

Q: How long does each cleaning cycle take?

A: Typical ultrasonic cleaning cycles last 3–5 minutes for everyday items like glasses or rings. Heavily soiled items may benefit from a second cycle. The mechanical controls make it easy to run multiple cycles as needed.

Q: Can I use tap water or do I need a special cleaning solution?

A: Plain tap water works well for most items. For a deeper clean, a small amount of mild dish soap or a dedicated jewelry cleaning solution can be added to the 440ml tank to boost results.
