How Does an Ultrasonic Jewellery Cleaner Work?

An ultrasonic jewellery cleaner uses rapid vibration to create tiny pressure changes in liquid. This liquid movement reaches edges, links, hinges and narrow spaces that are difficult to clean with a cloth.

The basic process

1. The tank is filled to the instructed level with water or an approved solution.
2. A transducer creates high-frequency vibration.
3. The vibration produces microscopic bubbles and fluid movement.
4. When those bubbles collapse, they help loosen surface residue from compatible items.

This process is often called cavitation. It does not make every stain disappear, and it does not make an unsuitable item safe to clean.

What it can help remove

• Skin oil and fingerprints
• Loose dust and everyday grime
• Residue around secure links, hinges and settings
• Particles in small crevices that are hard to wipe

What it cannot fix

An ultrasonic cleaner cannot repair scratches, restore worn plating, tighten stones or reverse permanent damage. It may not remove heavy tarnish without a suitable process, and harsh chemicals should never be improvised.

Why item compatibility matters

Vibration is useful for robust items but risky for porous gemstones, glued decorations, loose settings, damaged coatings and electronic watch movements. Always check the maker’s care instructions. Our compatibility guide covers common exclusions.

How to use one responsibly

1. Inspect the item and identify all materials.
2. Fill the tank according to the product instructions.
3. Place compatible items without overcrowding.
4. Run only the recommended cycle.
5. Remove, rinse if appropriate and dry thoroughly.
