Frequently Asked Questions

Q: What items can I safely clean in this ultrasonic cleaner?

A: This ultrasonic cleaner is ideal for jewelry (rings, necklaces, earrings, bracelets), eyeglasses and sunglass frames, watch straps, small metal tools, coins, keys, razor heads, and even dental appliances like retainers. Avoid placing soft gemstones (e.g. pearls, opals) or items with loose settings directly in the tank without checking manufacturer guidelines first.

Q: How much water or cleaning solution do I use?

A: Fill the 300ml tank with plain water or a mild cleaning solution up to the MAX fill line. Using a few drops of dish soap or a dedicated jewelry cleaning solution can enhance results. Never run the machine empty, as this can damage the transducer.

Q: How long should a typical cleaning cycle run?

A: For most jewelry and glasses, a 3–5 minute cycle is sufficient. The adjustable timer allows you to set cycles from 1 to 99 minutes, so you can experiment to find the best duration for your items. Heavily soiled pieces may benefit from a second cycle.

Q: Is this ultrasonic cleaner safe to use at home every day?

A: Yes. At only 15W, it is highly energy-efficient and designed for regular home use. The automatic shut-off timer ensures the machine stops safely when the cycle ends. Always ensure the tank contains liquid before operating.
