How to Clean Tarnished Silver Jewellery at Home

Open a drawer that hasn't been touched in a year and you'll find it: a pendant gone grey, a bracelet with that brownish film along the links, a ring that looks more pewter than silver. The first thought is usually that something has gone wrong with the piece. Nothing has. Silver tarnishes. It is the normal, expected behaviour of a metal that is mostly silver and a little bit copper, sitting in a room full of air.

The good news is that ninety per cent of the time, you can bring the piece back to a fresh, mirror-bright finish in about ten minutes with things that are already in your kitchen. The other ten per cent of the time, the piece needs a silversmith. This guide covers both — what to try at home, in what order, and how to spot the moment you should stop and ring someone who has a polishing motor and twenty years of muscle memory.

Tarnished sterling silver jewellery pieces arranged on a dark surface ready for cleaning

Why silver tarnishes in the first place

Sterling silver is 92.5% silver and 7.5% other metals — almost always copper, occasionally a little zinc or germanium in modern alloys. Pure silver itself tarnishes slowly. The copper does most of the darkening. When copper meets sulphur compounds in the air, it forms copper sulphide, which is dark brown or black. That film sits on the surface of the metal. It does not eat into the silver. It is not corrosion. It is a thin chemical coating that wipes off with the right method.

The sulphur comes from more places than most people realise. The biggest sources, in rough order:

Airborne hydrogen sulphide. Present in low concentrations almost everywhere, higher near coastal areas, geothermal regions, and anywhere with industrial activity. The reason a piece in a closed jewellery box still tarnishes is that the air inside the box contains it too.
Your skin. Body chemistry varies a lot person to person. Some people's sweat is mildly acidic and high in sulphur; their silver tarnishes within days of wearing. Others can wear the same piece for months with no change.
Cosmetics and toiletries. Perfume, hairspray, sunscreen, hand cream, and especially anything containing sulphur-based actives (some acne treatments, certain shampoos). Apply these, wait until they dry, then put the jewellery on.
Rubber and wool. Both off-gas sulphur compounds. Don't store silver on a rubber surface or wrapped in a wool cloth.
Eggs and onions. If you cook with these regularly and wear rings while cooking, that is where some of your tarnish is coming from.

Method one — silver polishing cloth

The first thing to try, every time, and the only thing that's actually needed for light tarnish. A proper silver polishing cloth (Town Talk and Goddard's are the British classics, but most jewellers' supply shops sell their own version) is a soft cotton or jeweller's cloth impregnated with a very fine polishing compound and a chemical anti-tarnish agent.

Rub the piece gently with the cloth. The cloth will darken; that's the tarnish lifting off. Move to a clean area of the cloth and continue. For a pendant or a flat ring, two or three minutes is usually enough. Don't wash the cloth — it loses its compound. When the whole cloth has gone dark, replace it. A cloth lasts six months to a year of regular use.

What the polishing cloth doesn't reach: chain links, the inside of a hollow bead, the recess of a stamped letter. For those, you need a wet method.

Method two — warm water and washing-up liquid

For pieces that are dull but not heavily tarnished — usually because they've been worn through hand cream and lotions and need a wash more than a polish. A small bowl of warm (not hot) water, two drops of plain washing-up liquid, the piece submerged for five minutes. Then a soft toothbrush — a baby toothbrush is perfect — worked gently over the surface and into any crevices. Rinse under clean running water. Dry with a soft cotton cloth, not a tea towel. Don't air-dry. Water marks on silver are surprisingly stubborn.

This won't remove deep tarnish. It will remove the surface film, the body oils, the lotion residue, and any general grime that's making a piece look tired without being darkly tarnished.

Method three — baking soda paste

When the polishing cloth isn't shifting it and washing-up liquid isn't enough, the next step up is bicarbonate of soda. Two teaspoons in a small dish, add water a drop at a time until it forms a paste the consistency of toothpaste. Apply with a finger or a soft cloth. Rub in small circles. The paste will turn grey as it lifts the tarnish. Rinse thoroughly and dry.

Important caveats. Baking soda is mildly abrasive. On a high-polished mirror finish, it leaves fine micro-scratches that will dull the shine over time if you do this every week. Use it only when needed, not as routine maintenance. And it will strip oxidation. If your piece has intentionally darkened recesses — the dark inside a stamped letter, an oxidised pattern between raised details — baking soda will lift all of that off. Stay away from oxidised pieces with this method.

Method four — the aluminium foil and salt bath

For the worst cases. A piece that has been in a drawer for years, that has gone almost black, that the cloth and the paste have both failed on. This method works because it is not abrasion — it is a small electrochemical reaction that pulls the sulphur off the silver and onto the aluminium.

Line a small heatproof bowl with aluminium foil, shiny side up.
Place the silver pieces on the foil. They must touch the foil — that's how the reaction happens.
Sprinkle a tablespoon of baking soda and a teaspoon of salt over the pieces.
Pour boiling water in to cover. You'll see the water fizz slightly and may smell a faint rotten-egg odour. That's the sulphur leaving the silver.
Leave for two to three minutes — longer for very heavy tarnish.
Lift out with tongs, rinse under cold water, dry with a soft cloth.

This method is dramatic. A bracelet that was almost unidentifiable as silver comes out looking new. But it has the same drawbacks as baking soda paste: it removes oxidation, and it can dull the finish on a high-polished piece by leaving the surface very slightly etched. Reserve it for the worst cases on plain silver. Never use it on pieces with stones, especially porous stones like pearl, opal, or turquoise, which the hot salt water will damage.

What about toothpaste?

You'll see this method everywhere. We don't recommend it. Most toothpaste contains silica or some other abrasive that's significantly harsher than baking soda. It will remove tarnish, but it will also leave scratches that show up as a hazy, micro-scuffed surface under any decent light. Once those scratches are there, only a polishing motor will take them out. Skip the toothpaste.

When to stop and call a silversmith

There are some situations where home cleaning will make things worse, or just won't work, and a piece needs to go to someone with proper kit:

Pieces with set stones. Most settings will survive a quick wash, but soaking, bath methods, or anything aggressive risks loosening claws, lifting glue under cabochons, or damaging porous gems. If a stone moves at all in its setting, stop wearing the piece and have it checked before any cleaning attempt.
Pieces with patina you want to keep. Some pieces have an oxidised finish that's part of the design. Once it's gone, only a jeweller can re-blacken it properly. If you're not sure whether the dark colour is intentional, ask the maker before cleaning.
Hollow or chambered pieces. Hollow beads, lockets, anything with an enclosed cavity. Wet cleaning gets water inside and the water doesn't come out. You'll get tarnish from the inside that's permanent and unreachable. These need a professional ultrasonic clean, with the piece dried in a heated cabinet afterwards.
Deep scratches or surface wear. Polishing compound only goes so far. A piece that has worn dull through years of contact with clothing, that has a scratch from a dropped key, or that has flattened areas from sliding against another ring — these need re-polishing on a wheel, which removes a thin layer of metal and restores the original finish.
Broken anything. A broken clasp, a parted chain link, a thin spot. Cleaning a broken piece is a waste of effort because the moment you wear it again, it'll fail. Get the repair first.

Once it's clean, keeping it clean

The best cleaning routine is the one you don't have to do. A few habits prevent most of the tarnish:

Wear the piece. Silver worn daily stays bright. The slight friction of skin and clothing keeps the surface working, and the natural oils slow the chemical reaction. The worst-tarnished pieces in any collection are always the ones that sit unworn for months at a time.
Store in an airtight bag. A small zip-lock pouch with the air pressed out, one piece per bag so they don't scratch each other. A piece in a sealed bag with an anti-tarnish strip can sit unworn for years and come out looking the same.
Take it off for water. Showering, swimming, washing up. Chlorine and salt water both speed tarnish dramatically, and chlorine in particular can actually damage the silver over time, not just discolour it.
Anti-tarnish strips in the box. Cheap, available from any jeweller's supply or online. They absorb sulphur compounds from the air. Replace every six months.
Cosmetics first, jewellery second. Perfume, moisturiser, sunscreen, hairspray — all on, all dry, then put the jewellery on. Reverse that order and the tarnish starts immediately.

Questions about a particular piece

If you've got a piece you're not sure about — whether the dark colour is tarnish or intentional oxidation, whether the cleaning will damage a stone, whether a piece is worth saving — email [email protected]. A photograph is usually enough for us to say. We do re-polishing and stone-tightening on pieces that weren't made by us; small repairs are usually a same-day job.
