How to Care for Gold Jewellery: Cleaning & Storage

The Short Answer

Clean solid gold in warm water with a few drops of mild washing-up liquid, soak for fifteen to twenty minutes, brush gently with a soft toothbrush, rinse over a bowl and dry with a lint-free cloth. Take gold off for swimming — chlorine attacks the alloy metals — and for the gym, gardening and cleaning. Put lotions and perfume on before your jewellery, store each piece separately with chains fastened, and have rings with stones checked once a year. White gold needs one extra thing: its rhodium plating wears and has to be renewed.

This guide is specific to gold — the alloys, white gold’s plating, chains and clasps. For stones and other metals, our fine jewellery care chart sets out what is safe for each material, including when an ultrasonic cleaner is a mistake.

Common problems and their fixes.

Safe Cleaning at Home

Warm water with a few drops of mild dish soap, soak for 15–20 minutes, agitate gently with a soft toothbrush, rinse thoroughly, dry with a lint-free cloth. This restores shine to most plain gold pieces without risk, and the Gemological Institute of America recommends the same warm water, mild soap and soft brush as the safe default for most gems. Rinse over a bowl or with the plug in, not over an open drain.

What to Never Use

Avoid toothpaste, baking soda and vinegar — they scratch or etch the surface. Ultrasonic cleaners can loosen stones and damage enamel or pearl accents. Commercial silver dips should never be used on gold.

Storage

Store pieces individually in soft pouches or a compartmented box to prevent scratching. Keep them away from humidity, which tarnishes alloys. Fasten clasps before storing so chains cannot knot.

Professional Maintenance

See a jeweller once a year to check prongs and clasps, clean the piece professionally, and re-plate white gold. Regular maintenance prevents stone loss and structural failure and is far cheaper than repair after damage.

White Gold Needs Different Treatment

White gold is not naturally white. It is yellow gold alloyed with pale metals — usually palladium, nickel or silver — which lightens it to a faintly warm grey, and then it is plated with rhodium to make it properly white and bright.

That plating is a wear layer, and it wears. It goes first at the points of most contact: the underside of a ring shank, the high edges of a setting, the inside of a bangle. The symptom is a warm, slightly yellow patch appearing through the white, and it is not damage — it is the underlying alloy showing.

Re-plating is inexpensive and routine, and a piece worn daily typically needs it every year or two. It is worth doing before the alloy beneath starts to abrade rather than after.

Two consequences for care. First, anything that accelerates surface wear — abrasive polishing cloths, aggressive cleaning, gritty hand creams — shortens the interval. Second, if you react to jewellery, ask what the white gold is alloyed with: nickel-alloyed white gold under a worn rhodium layer is a common cause of a reaction that appears years after purchase, because the plating was the barrier.

Chains, Knots and the Failures You Can Prevent

Chains fail in predictable places and almost all of it is preventable.

Knots are the commonest cause of a broken chain, and they come from storing a chain loose and unfastened. A tangled chain is then pulled straight, which stresses individual links. Fasten the clasp before storing and lay the chain flat or hang it.

The jump ring connecting the clasp to the chain is usually the weakest point, because it is often a simple open ring rather than a soldered closed one. If a chain repeatedly comes undone, the fix is usually a soldered jump ring rather than a new clasp.

Fine chains under a heavy pendant are a mismatch that eventually breaks. If a pendant feels heavy for the chain, it is.

Sleeping in a chain is how most of them fail — a night of movement against a pillow, with the chain unsupported, does more work than a day of wear.

What to do if a chain does break: keep every piece, including the loose links, and take them to a jeweller rather than attempting a repair. A single soldered link is cheap. A chain repaired at home with a jump ring from a craft shop is a chain that will fail again at the same spot.

Travelling With Gold Jewellery

Jewellery is lost and damaged in transit more than at home, and a few habits cover most of it.

Never put it in checked luggage. Airline liability for jewellery in hold baggage is typically excluded or severely limited, and most travel insurance policies apply a low single-item limit and often exclude items not carried on the person.

Use a proper roll or case rather than a wash bag. Pieces rubbing against each other in transit is how soft gold gets scratched, and hard stones scratch soft metal readily.

Take less than you want to. The realistic question is what you would be content to lose, not what you would like to wear.

Photograph what you take, before you go, so you can prove ownership and condition. Our guide to photographing jewellery for insurance covers the shots that actually help.

Check the destination. Some countries require declaration of valuables above a threshold on entry, and being able to show prior ownership stops you being taxed on your own possessions coming home — our guide to buying jewellery abroad covers the customs side.

Take it off for the pool and the beach. Chlorine and salt water are the two most reliable ways to damage alloyed gold, and sun cream leaves a film that is unusually persistent.

The Annual Check, and What a Jeweller Is Actually Looking At

The recommendation to have pieces checked yearly is easy to ignore because nothing appears to be wrong. What the jeweller is looking for is the state before something goes wrong.

Claw wear. Prongs holding a stone wear down from the top. A claw that has gone from rounded to flat has lost most of its grip, and the stone is a knock away from being lost. Retipping is inexpensive; replacing a stone is not.

Shank thinning. A ring worn daily wears at the bottom where it meets the palm. Caught early, metal can be added. Left, the shank cracks and needs full replacement.

Clasp and hinge wear. Box clasps and lobster clasps develop play, and a clasp with visible movement is one that will open unprompted.

Stone movement. A jeweller will tap a piece near the ear and listen — a loose stone rattles audibly long before it looks loose.

Setting distortion. Bezels and channels bend from impact, and a bent channel loosens every stone in it.

Most of these are cheap to correct and expensive to ignore. Our repair guide covers what each job involves and what to specify.

When Not to Clean It Yourself

The home cleaning method above is safe for plain solid gold and for hard stones in secure settings. Several categories are not.

Pearls, opal, turquoise, coral, amber and emerald should not be soaked, and none of them should ever go in an ultrasonic cleaner. Pearls in particular are dissolved by acid and damaged by detergent — wipe with a damp cloth and nothing more, as our pearl guide sets out.

Anything with visible fractures or existing damage, because water and mechanical agitation propagate a crack.

Foil-backed antique settings, where moisture behind the stone destroys the foil permanently and cannot be reversed.

Enamel and niello work, which lifts.

Pieces with existing loose stones, where cleaning is exactly how they get lost down a drain. If something rattles, do not clean it — get it tightened first.

When in doubt, the cost of professional cleaning is small, and a jeweller will decline to ultrasonic something that should not be ultrasoniced. That judgement is what you are paying for.
