OSLTWI Ultrasonic Jewellery Cleaner 48kHz — 350ml Stainless Steel Tank, 2 Timed Modes for Rings & Eyeglasses

OSLTWI Ultrasonic Jewelry Cleaner is a compact 48kHz ultrasonic cleaning unit that refreshes jewelry, eyeglasses, watch bands and dentures using water-only cleaning or optional solution in two timed modes.

This ultrasonic cleaner combines a 350ml 304 stainless steel tank with a 48kHz transducer to dislodge dirt and oils from small valuables quickly and gently. Lightweight and easy to operate, the unit offers two preset cycles (5 minutes gentle and 7 minutes intensive) and stops automatically when the cycle ends. Designed for regular at‑home maintenance, it’s intended to reduce the need for harsh scrubbing and can be used with plain water or a dedicated cleaning solution for tougher grime.

How does the 48kHz ultrasonic technology clean delicate items?

The cleaner emits high-frequency sound waves that create countless microscopic bubbles in the water; when those bubbles collapse near surfaces, they lift away contaminants without abrasive contact. Because the tank is made from 304 stainless steel that is softer than many gemstones and metals, items are protected from scratching during the process. This method reaches crevices and settings that are hard to clean by hand.

• 48kHz frequency for fine, consistent cavitation action
• 304 stainless steel tank that minimizes abrasion risk
• Effective on chains, prongs, clasps and textured surfaces
• Removes oils, dust, and everyday residue from small items

Can I use this cleaner without special chemicals?

Yes — the OSLTWI unit is designed to perform well with plain tap water for everyday refreshes, making it a cost-saving option compared with recurring chemical solutions. For stubborn, set-in dirt you may choose a mild ultrasonic cleaning solution, but routine cleaning typically requires only water. Using water-only cycles also reduces exposure to strong solvents and simplifies maintenance.

• Water-only operation for most daily cleaning jobs
• Optional mild solutions can be used for tougher residues
• Simple rinse and dry after each cycle; no special disposal
• Lower annual running cost versus frequent professional cleanings

What items are safe to clean with this machine?

The cleaner is suitable for many everyday valuables including gold, silver, plated pieces, diamonds, eyeglasses, stainless watch bands, and removable dental appliances. Avoid immersing porous gems (like opal or amber) or items with delicate lacquered finishes unless the manufacturer permits ultrasonic cleaning. When in doubt, test a single small item or consult the item's care guidelines.

• Works well for rings, necklaces, bracelets, earrings and eyeglasses
• Safe for most metals and durable gemstones at 48kHz
• Not recommended for fragile, porous, or soft organic gems
• Use a basket or mesh tray to protect small or lightweight pieces

How simple is it to operate and store this ultrasonic cleaner?

Operation is one-touch: fill the tank, place items, choose the 5- or 7-minute mode, and press start; the unit pauses automatically when the program ends. Weighing only 0.57 kg and with a compact footprint, the cleaner tucks easily into a drawer or shelf when not in use. Its straightforward controls make it suitable for users who prefer quick, repeatable results without technical setup.

• One-touch mode selector with automatic cycle stop
• 5-minute gentle and 7-minute intensive presets for convenience
• Lightweight 0.57 kg design for easy portability and storage
• 350ml tank capacity fits multiple small items at once
