Frequently Asked Questions

Q: What can I clean with this digital ultrasonic cleaner?

A: This ultrasonic cleaner is incredibly versatile. It can safely clean jewelry, watches, eyeglasses, dentures, shaver heads, camera lenses, circuit boards, electronic components, surgical instruments, fruits, and vegetables. It's also useful for mixing drinks or blending chemical reagents in a lab setting.

Q: What is the difference between the 30W and 50W versions?

A: The 30W version is ideal for everyday cleaning of smaller items like jewelry and glasses with shorter cycles. The 50W version delivers more powerful ultrasonic vibrations, making it better suited for stubborn grime on heavier components like circuit boards, automotive parts, or surgical instruments that require deeper cleaning.

Q: Can I run the ultrasonic cleaner without water?

A: No — never run the unit without water or liquid in the tank. Operating dry, even for just a few seconds, will permanently damage the vibration plate. Always fill the tank to the appropriate level before switching the machine on.

Q: Is this ultrasonic cleaner safe for delicate items like gemstone jewelry?

A: The 40kHz ultrasonic cleaning is gentle enough for most metals and hard gemstones. However, soft or porous stones (e.g., pearls, opals, emeralds) and items with glued settings may not be suitable for ultrasonic cleaning. When in doubt, test with a short cycle and inspect the item afterward.

Q: Does the timer automatically shut off the machine?

A: Yes. The digital timer allows you to set a cleaning duration from 1 to 59 minutes, and the machine will automatically stop at the end of the selected cycle, giving you hands-free convenience and preventing over-cleaning.
