Cleaning delicate items like jewelry and eyeglasses can be challenging. Traditional brushing may not reach tiny crevices.
Ultrasonic cleaning offers a more advanced solution.
How Ultrasonic Cleaning Works
Ultrasonic cleaners use high-frequency sound waves (commonly 40kHz) transmitted through water.
These waves create microscopic bubbles in a process called cavitation.
When the bubbles collapse, they gently lift residue from small gaps and crevices.
Check Compatibility Before Cleaning
An item is suitable only when its manufacturer, jeweler or eye-care professional allows ultrasonic cleaning. Check gemstone treatments, loose settings, coatings, adhesives, plated finishes and watch or eyewear instructions. “Water-resistant” does not automatically mean “ultrasonic-safe.”
GIA cautions against ultrasonic cleaning for many treated, porous, organic or heat-sensitive gems and notes that vibration can loosen stones. When an item’s materials or treatment history are unknown, use the care method recommended by a qualified professional.
Key Features to Look For
1. Item-Specific Compatibility Guidance
Frequency alone does not prove that a cleaner is safe for a particular item. Start with the item and cleaner instructions.
2. Stainless Steel Tank
Durable and corrosion-resistant.
3. Clearly Labeled Timer Settings
Use the shortest cycle permitted by the item and cleaner instructions, then inspect the item before repeating.
4. Automatic Cycle Stop
An automatic stop makes cycle timing easier, but it does not replace compatibility checks or supervision.

FAQ
Can ultrasonic cleaners damage jewelry?
Yes. Treatments, fractures, porous or organic materials, heat-sensitive gems and loose settings can be damaged or loosened. Even diamond jewelry should be inspected for treatments and setting security before ultrasonic cleaning.
What liquid should I use?
Use only the liquid permitted by both the cleaner instructions and the item’s care guidance. Do not add household chemicals by default.
