Can chlorine damage gold rings?

Safest home method: warm water, a drop of Dawn, 20 minutes soak, soft toothbrush on the underside, pat dry. Skip toothpaste, skip paper towels (they scratch). Do this every 2-4 weeks and your ring will look new.

Ultrasonic cleaners are safe for diamonds, sapphires, rubies, and plain gold bands. They are NOT safe for pearls, opals, emeralds, turquoise, or any fracture-filled stones. If you are unsure, use warm soapy water instead.

Pearls need gentle care: wipe with a soft damp cloth after wearing, avoid perfume and hairspray on them. Never soak them, never ultrasonic them. Re-string pearls every 2-3 years because silk stretches. Store flat, not hanging.

Steam and ultrasonic work by dislodging grease and skin oil. They are safe for hard, non-porous stones. Never on pearls, opals, emeralds, or stones with glue settings. That is why your jeweler asks what stone you have first.
