Ultrasonic cleaners use cavitation to remove dirt from jewelry. They work best on hard gems (diamonds, sapphires) and solid metal settings, but can damage pearls, porous stones, glued pieces, and treated gems. Inspect pieces first and consult a jeweler for high-value or delicate items.
Jewelry steam cleaners use hot vapor to remove grime without abrasive scrubbing. They work well for hard gemstones and solid metal settings, but can damage porous or treated stones - so match the method to the piece and consult a jeweler.
A professional jewelry cleaner restores shine, inspects for loose settings, and handles repairs that home cleaning can't. Learn about tools (polishers, buffers, ultrasonic), which pieces need special care, and what to expect from a jeweler.
