Frequently Asked Questions

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

A: This digital ultrasonic cleaner is suitable for a wide variety of items including jewelry, rings, necklaces, eyeglasses, watches, shaver heads, dentures, camera lenses, circuit boards, electronic components, surgical instruments, and even fruits and vegetables. It can also be used to mix or emulsify liquids and chemical reagents.

Q: Can I use cleaning solution instead of water in the ultrasonic cleaner?

A: Yes, you can use mild cleaning solutions or detergents specifically designed for ultrasonic cleaning baths. Water alone works for many items, but a diluted cleaning solution can improve results for heavily soiled jewelry or metal parts. Avoid flammable solvents or harsh chemicals not rated for ultrasonic use.

Q: What's the difference between the 30W and 50W models?

A: The 30W model is ideal for lighter cleaning tasks and more delicate items, such as jewelry and eyeglasses. The 50W version provides stronger ultrasonic power for more stubborn grime and heavier-duty cleaning, such as circuit boards or machine parts. Both models operate at 40KHz frequency and feature a 500ml stainless steel tank.

Q: Is it safe to clean gemstone jewelry in the ultrasonic cleaner?

A: Most hard gemstones like diamonds, sapphires, and rubies are safe to clean ultrasonically. However, softer or porous stones such as opals, pearls, emeralds, or turquoise should not be placed in ultrasonic cleaners as the vibration may cause damage. When in doubt, consult a jeweler before cleaning valuable pieces.

Q: How long should each cleaning cycle be?

A: For most everyday items like glasses and jewelry, a 3–5 minute cycle is typically sufficient. The digital timer allows you to set cycles from 1 to 59 minutes, so you can adjust based on how soiled the item is. Heavily contaminated components may benefit from a second cycle.
