How to Clean Jewellery at Home: Gold, Silver, Pearls and Gems
The short answer
The safest way to clean most gold, platinum, and diamond jewelry at home is lukewarm water with a few drops of mild dish soap and an ultra-soft toothbrush. Never use boiling water, baking soda, or ultrasonic cleaners on organic gems like pearls or porous, treated stones like emeralds and opals, which can fracture or lose their luster.
The Universal Standard: Mild Soap and Warm Water
For 90% of jewellery—including gold, platinum, diamonds, rubies, and sapphires—the safest cleaning routine requires only three household items:
- A small bowl of lukewarm water (never hot or boiling).
- A few drops of gentle, fragrance-free liquid dish soap.
- An ultra-soft baby toothbrush or cosmetic brush.
Soak the piece for 10 to 15 minutes to loosen oils and hand lotions, gently brush behind the stone settings, rinse in a separate bowl (never over an open sink drain!), and pat dry with a lint-free microfibre cloth.
Ultrasonic Cleaners: Safe for Diamonds, Lethal for Emeralds
Ultrasonic cleaners use high-frequency sound waves to create microscopic cavitation bubbles that scrub away grime. While ideal for plain platinum bands and untreated diamonds, they can destroy other precious stones:
- Never put in an ultrasonic: Emeralds (vibrations shatter the stone and strip oil fillers), opals, pearls, tanzanite, turquoise, and any fracture-filled gemstones. Read our guide on gemstone treatments.
- Safe for ultrasonics: Solid platinum, unplated gold, and untreated diamonds or sapphires with tight prongs.
Organic and Porous Gems: Pearls, Opals, and Coral
Organic gems require completely different care because they absorb liquids and chemicals:
Pearls: Composed of delicate nacre (calcium carbonate). Never submerge a pearl strand in water, as water weakens the silk string. Wipe pearls after every wearing with a damp, soft cotton cloth. See how to tell if pearls are real.
Opals: Opals contain up to 20% water. Sudden temperature shifts or dry heat can cause cracking (crazing). Clean gently with a damp cloth only.
Sterling Silver Care and Tarnish Removal
Silver tarnishes naturally when exposed to airborne sulphur compounds. The safest way to restore shine to sterling silver is a treated jewellery polishing cloth. Avoid harsh liquid silver dip baths, which strip natural antique oxidation from engraved patterns and leave the silver prone to rapid re-tarnishing. See our guide on silver hallmarks.
Dangerous DIY Internet Cleaning Trends to Avoid
Many viral cleaning hacks cause permanent, irreversible damage to fine jewellery:
- Toothpaste: Contains abrasive silica particles that scratch gold, platinum, and softer gemstones.
- Baking soda and aluminium foil: Can strip protective rhodium plating and etch delicate stones.
- Bleach and chlorine: Chemically attacks the alloy metals in karat gold, causing structural stress corrosion cracking where prongs snap off.
When to Visit a Professional Bench Jeweler
If you hear a stone rattling in its setting, notice bent prongs, or have antique family heirlooms with unknown treatments, do not attempt home cleaning. A bench jeweller can tighten loose stones and safely ultrasonic clean the piece after securing it. Learn more in our guide on inherited jewellery.
Common questions
Can I clean my diamond ring with rubbing alcohol or hand sanitiser?
Pure isopropyl alcohol will not harm diamonds or gold, but frequent exposure can dry out organic stones and leaves a dull film from sanitiser moisturizers.
How often should I clean my everyday rings?
A gentle soak in warm soapy water once every two to three weeks keeps diamond prongs and pavilion facets free of lotion and dust buildup.
Can boiling water sterilise jewellery safely?
No. Thermal shock from boiling water can crack gemstones instantly, dissolve adhesives in vintage jewellery, and damage delicate settings.
