Do I Need to Add Cleaning Agents When Using an Ultrasonic Cleaner for Jewellery?

1. Cases Where Cleaning Agents Are Optional

Applicable Scenarios:

Jewellery only has water-soluble dirt like dust or light sweat stains.

Method:

Clean directly with room-temperature or lukewarm (≤40°C) distilled or deionised water in the ultrasonic cleaner.

Avoid prolonged cleaning (recommended 1-3 minutes) to prevent gemstone loosening or metal wear.

2. Cases Where Specialised Cleaning Agents Are Recommended

Applicable Scenarios:

Jewellery has stubborn grease, makeup residue, or tarnish (e.g., silver jewellery).

Recommended Cleaning Agents:

Neutral jewellery cleaning solution (pH=7, non-corrosive, suitable for most gemstones and metals).

Mild soapy water (a small amount of pH-neutral dish soap mixed with warm water, suitable for gold, diamonds, etc.).

Specialised silver cleaner (contains anti-tarnish agents, ideal for oxidised silver).
