You can clean jewelry, eyeglasses, rings, retainers, watch straps, and other water‑safe metal accessories with Osmo JewelPure’s ultrasonic waves; avoid porous or fragile stones like pearls and emeralds which aren’t suited for ultrasonic cleaning.

Osmo JewelPure offers two preset cleaning cycles — a quick 5‑minute cycle for routine maintenance and a 7‑minute deep cycle for tougher buildup — simply activated with single or double button presses.

Water alone works, but adding a mild dish soap or a jewelry‑safe ultrasonic cleaning solution helps lift oils and stubborn grime more effectively than plain water.

After use, unplug the unit, empty the tank, and wipe it with a soft cloth; regular cleaning helps maintain performance and prevents residue buildup.

Ultrasonic cleaning is great for dirt and oils but does not remove oxidized rust or heavy tarnish — those often require separate rust/tarnish treatments before ultrasonic cleaning.

If it’s still dull, it may have surface scratches or deep oxidation that ultrasonic cleaning alone can’t fix; rinsing properly and using a dedicated solution can help, but sometimes polishing is needed.
