How to Clean Jewelry with a Home Ultrasonic Cleaner

1. Introduction to Ultrasonic Jewelry Cleaning

Ultrasonic cleaners use high-frequency sound waves to remove dirt, oils, and tarnish from jewelry. They are highly effective for home use but require proper settings and solutions to avoid damaging delicate pieces.

2. Types of Jewelry Safe for Ultrasonic Cleaning

✅ Safe to Clean:

• Gold & Platinum: Durable metals handle ultrasonic cleaning well.
• Sterling Silver: Effective for removing tarnish (use anti-tarnish solution afterward).
• Diamonds & Hard Gemstones (Ruby, Sapphire, Moissanite): Resistant to ultrasonic vibrations.

❌ Avoid Ultrasonic Cleaning for:

• Pearls, Opals, Emeralds, & Organic Gems: Can crack or lose luster.
• Gold-Plated or Costume Jewelry: Risk of peeling or fading.
