Frequently Asked Questions

Q: What items can I clean with this mini ultrasonic cleaner?

A: The 750ml ultrasonic cleaner is ideal for cleaning jewelry, eyeglasses, watch bands, coins, small metal parts, dental retainers, and electronic components. Its 42KHz ultrasonic waves reach into tiny crevices that brushes can't, delivering a thorough clean without scratching delicate surfaces.

Q: How does USB / Type-C power work with this ultrasonic cleaner?

A: The cleaner is powered via a standard USB or Type-C connection, meaning you can plug it into a laptop, power bank, USB wall adapter, or any compatible charger. This makes it highly portable and convenient for home, travel, or office use — no proprietary adaptor required.

Q: How long does a cleaning cycle take?

A: You can set the digital timer from 1 to 5 minutes per cycle, with a total operating range of up to 30 minutes. Most items are thoroughly cleaned in just one or two short cycles. Simply add water (and optionally a few drops of mild cleaning solution), place your items in the tank, set the timer, and let the ultrasonic waves do the work.

Q: Is this ultrasonic cleaner safe for jewelry and eyeglasses?

A: Yes — the 42KHz ultrasonic frequency is widely used for delicate items like rings, necklaces, and eyeglass frames. However, always check whether specific gemstones (e.g. opals, emeralds, or glued settings) are ultrasonic-safe before use, as some porous or heat-treated stones may be sensitive to cavitation vibration.
