kunphy Ultrasonic Jewelry Cleaner 400ml Sonic Cleaner for Rings & Glasses — 48kHz Quiet Cavitation

The KUNPHY Ultrasonic Jewelry Cleaner is a 400ml sonic cleaning device that uses 48kHz cavitation to remove dirt from rings, glasses and small accessories quickly and quietly.

Designed for home use and travel, this compact ultrasonic cleaner combines a roomy 400ml SUS304 stainless steel tank with a high-frequency 48kHz transducer to dislodge grime from hard-to-reach crevices without harsh scrubbing. A clear LED display, two timer settings, overheat protection and a low-noise motor make it practical for daily maintenance of metal jewelry, eyewear and dental appliances. The non-magnetic liner and anti-slip base boost durability and stability while the lightweight build keeps it portable.

How does the 48kHz ultrasonic action clean jewelry effectively?

The cleaner generates microscopic cavitation bubbles that implode near the surface of items, gently lifting oils, dust and residues from tiny gaps and settings. Because it relies on mechanical agitation in liquid rather than abrasive contact, it reaches places a cloth or brush can’t.

• 48kHz frequency for fine cavitation targeting small crevices
• Removes oils, dirt and grime without scratching metals and stones when used correctly
• Compatible with warm water and mild solutions for improved results

What items can I safely clean with this machine?

The KUNPHY unit is suitable for sturdy metals and most gemstones: gold, silver, diamonds and daily-wear pieces respond well. It also refreshes eyeglasses, retainers, dentures and small metal components, but delicate or glued items need caution.

• Safe for solid gold, silver and diamond jewelry when used with warm water
• Works well on eyewear frames, watch bands and dental appliances
• Not recommended for glued pavé settings, pearls, opals or porous gemstones

How do the LED display, timers and noise level improve daily use?

The easy-to-read LED screen shows remaining runtime and lets you choose 5 or 10 minute cycles for consistent cleaning. The motor runs below 45dB, so it’s unobtrusive in home environments, and built-in overheat protection preserves the unit’s lifespan.

• Two preset timers (5 and 10 minutes) for repeatable cleaning sessions
• Quiet operation under 45dB for living-room or bedroom use
• Overheat protection and anti-slip base for safe, stable operation

Why is the 400ml SUS304 tank important, and how should I use it?

The upgraded 400ml stainless steel tank accommodates bulky items like large glasses or multiple pieces at once, while the SUS304 construction resists corrosion and supports long-term use. Fill with warm water and, if needed, a mild cleaning solution; avoid hard impacts and excessive detergents.

• 400ml capacity fits larger frames and multiple jewelry pieces
• SUS304 stainless steel tank provides durability and non-magnetic protection
• Use warm water and gentle solutions; do not overload the tank

Who is this for? The KUNPHY Ultrasonic Jewelry Cleaner is intended for people who want an easy, nonabrasive way to maintain everyday jewelry, eyewear and small personal items without professional costs. It’s a good match for busy homeowners, frequent travelers who value a lightweight device, and anyone who prefers scheduled, hands-off cleaning for rings, earrings, glasses and dental appliances. Avoid using it for glued or soft gemstones and consult a jeweler for fragile or heirloom pieces.
