Frequently Asked Questions
Q: What items can I safely clean in this ultrasonic cleaner?
A: This ultrasonic cleaner is safe for eyeglasses, sunglasses, metal jewelry (rings, necklaces, earrings, bracelets), watch faces and metal bands, dental retainers, dentures, coins, and small metal accessories. Avoid placing items with delicate gemstone settings that may be loosely glued, or soft porous materials not suited to water immersion.
Q: Do I need to use special cleaning solution, or will water work?
A: Plain water works well for most everyday cleaning tasks. For heavier residue on jewelry or watch parts, you can add a small drop of mild dish soap or a commercially available ultrasonic cleaning solution to the water for enhanced results.
Q: How does the auto ON/OFF feature work?
A: Simply select your preferred timer — 3, 5, or 10 minutes — and the cleaner will run for the chosen duration and then automatically shut off. This prevents over-cleaning and saves energy, so there's no need to watch the clock.
Q: How do I power this ultrasonic cleaner?
A: The unit is powered via USB / Type-C cable, making it compatible with any standard USB wall adapter, laptop port, or power bank. No proprietary power supply is needed, which makes it very convenient for travel and home use alike.
