How to Clean Gold Jewelry Safely at Home (Step by Step)
Why gold gets dirty
Pure gold does not rust or tarnish, but jewelry is an alloy: 14K gold is only 58.5% gold, and the copper and silver in it can darken slightly over time. Most of the dullness, though, is a film of skin oils, soap, lotion and dust, especially behind stones and in chain links. Removing it restores the shine in minutes.
The safe home method
- Prepare the bath. Fill a bowl with warm (not hot) water and add a few drops of mild dish soap. Avoid soaps with moisturisers or strong degreasers.
- Soak. Leave solid gold pieces for 15–20 minutes. This softens the grime.
- Brush gently. Use a soft baby toothbrush, paying attention to the back of settings, clasps and engravings.
- Rinse. Rinse under warm running water — with the sink plugged or in a strainer so nothing goes down the drain.
- Dry and polish. Pat dry with a lint-free cloth, then buff with a jewelry polishing cloth. Let pieces with stones air-dry completely.
Do this every few weeks for pieces you wear daily. A quick wipe with a soft cloth after wearing keeps the film from building up.
What never to use
- Chlorine and bleach: they attack the other metals in the alloy and can make gold brittle and crack over time. Take rings off before pools, hot tubs and cleaning with bleach.
- Toothpaste, baking soda and abrasive powders: they leave fine scratches, especially on 18K–24K gold, and strip plating.
- Acetone, ammonia in strong solutions and harsh chemicals: they can damage stones, glues and finishes.
- Boiling water: sudden heat can crack some stones and loosen glued settings.
- Paper towels and tissues: their fibres can scratch soft gold.
Special cases
White gold
Most white gold is plated with rhodium, a bright white metal. Clean it the same way, gently. When the yellowish base starts to show through — often every one to three years on rings — a jeweler can re-plate it. Read white, yellow and rose gold for why.
Gold-plated, vermeil and gold-filled
The gold layer is thin, so skip soaking for long, never scrub and use only a soft cloth with a little soapy water. Polishing cloths with abrasive compounds can wear through plating. See gold-plated vs gold-filled vs solid gold.
Jewelry with gemstones
Diamonds, sapphires and rubies tolerate the soap-and-brush method well. Pearls, opals, emeralds, turquoise, coral and amber are soft or porous: do not soak them, wipe them with a damp cloth and keep them away from ultrasonic cleaners and steam. Check stone settings for looseness while you clean.
Gold coins
Do not clean collectible coins at all: cleaning leaves marks that reduce their value to collectors. Bullion coins can be rinsed in water and patted dry, but most buyers prefer them untouched.
Ultrasonic cleaners and professional cleaning
Ultrasonic cleaners use vibrations in a liquid to shake grime loose. They work well on solid gold and diamond jewelry, but they can loosen stones in weak settings and damage soft or treated gemstones. Many jewelers clean and inspect jewelry for free or for a small fee, and they will also check prongs and clasps — worth doing once or twice a year for pieces you wear every day.
How to store gold
- Keep each piece separate, in a soft pouch or a lined box, so harder pieces do not scratch softer ones.
- Fasten chains and lay them flat to avoid knots.
- Store away from humidity and household chemicals; a silica gel packet in the box helps.
- Put jewelry on after lotions, perfume and hairspray, and take it off for sport, cleaning and swimming.
Does cleaning change the value?
For jewelry, a clean piece looks better and can get a better offer, but the gold value depends only on weight and purity — cleaning does not add or remove gold. You can check what your piece is worth with the jewelry price calculator or the scrap gold calculator.
