How to Care for Sterling Silver Jewellery (Complete Guide)
Simple tips to keep your sterling silver rings, necklaces, and earrings bright and tarnish-free.
Why does sterling silver tarnish?
Sterling silver is an alloy: 92.5% pure silver and 7.5% copper, which is why pieces are often stamped S925. The copper component is what causes tarnishing — it reacts with sulfur compounds in the air, with moisture, and with the natural oils and acids on your skin to form a dark surface layer called silver sulfide. This is a chemical reaction, not a sign of poor quality. Even fine jewellery from the world's best silversmiths tarnishes eventually.
The rate of tarnishing varies by environment. Humid climates, coastal air (which carries salt), perfume, hairspray, and even some foods accelerate the process. That's why a ring worn in a humid Australian summer kitchen tarnishes faster than one worn in a dry, climate-controlled office. The good news is that tarnish is purely surface-level — the silver beneath is completely intact, and with the right approach, any tarnished piece can be restored to its original brightness in minutes.
Daily care habits that prevent tarnish
The single most effective habit is putting jewellery on last. Apply perfume, sunscreen, moisturiser, and hairspray before putting on your rings, necklaces, and earrings. These products contain chemicals that accelerate tarnishing and can dull the surface finish. Once they've been absorbed or dried, they're far less damaging to jewellery that comes into contact with them.
Remove sterling silver before showering, swimming, or any activity that involves prolonged water exposure. Chlorinated pool water is particularly harsh — it strips protective coatings and accelerates oxidation noticeably. After wearing, give pieces a quick wipe with a soft, lint-free cloth before storing them. This takes ten seconds and removes skin oils and light residue before they have a chance to start the tarnishing process. These two habits alone — on last, off first, and a quick wipe down — will extend the life of a sterling silver piece significantly.
How to clean sterling silver at home (3 methods)
Method 1 — Warm water and mild dish soap: Fill a small bowl with warm (not hot) water and add two or three drops of mild dish soap. Soak the piece for 5–10 minutes, then use a soft toothbrush to gently scrub crevices. Rinse thoroughly under clean warm water and pat dry with a lint-free cloth. Leave to air-dry completely before storing. This is the safest method for all sterling silver pieces including those with gemstone settings.
Method 2 — Baking soda paste: Mix baking soda with a small amount of water to form a thick paste. Apply to the piece using a soft cloth or your fingertip and rub gently in small circular motions. The mild abrasive action lifts tarnish without scratching. Rinse thoroughly and dry completely. Avoid using this method on pieces with soft stones like pearls, opals, or turquoise, as the abrasive action can scratch delicate surfaces.
Method 3 — Polishing cloth: A silver polishing cloth (available at most jewellery and hardware stores) is the fastest option for light tarnish and everyday maintenance. The cloth is impregnated with a cleaning compound — rub the tarnished area with firm but gentle pressure until the shine returns. No rinsing or drying required. Keep one in your jewellery box for quick touch-ups. For heavier tarnish, combine with Method 1 first, then finish with a polishing cloth for maximum shine.
Storage tips to slow tarnish
How you store silver between wearings is as important as how you clean it. Air exposure is the main driver of tarnish, so the goal is to minimise contact with air when pieces aren't being worn. Small resealable zip-lock bags are one of the most effective storage solutions: press out as much air as possible before sealing, and store each piece separately to prevent scratching. Anti-tarnish strips (available cheaply online or in jewellery supply stores) placed inside the bag or jewellery box absorb sulfur compounds from the surrounding air and can extend tarnish-free storage by months.
If you use a jewellery box, line it with a soft fabric insert and keep compartments separate. Storing pieces together allows them to scratch each other — silver is a relatively soft metal — and the surface damage from scratching is harder to reverse than tarnish. Keep your jewellery box in a cool, dry location away from direct sunlight and humidity. A bedside drawer or a dressing table in a low-humidity room is ideal. Avoid storing silver in the bathroom, where heat and humidity from showering create the worst possible conditions for the metal.
When to re-polish or re-plate
For most pieces, the cleaning methods above are sufficient to maintain shine indefinitely. However, if a piece has deep scratches, pitting, or tarnish that doesn't respond to home cleaning, a professional jeweller can re-polish the surface back to its original finish. This is worth doing for pieces you wear regularly or those with sentimental value — re-polishing is typically inexpensive and takes the piece back to new condition.
Gold-plated sterling silver requires slightly different care. The gold layer sits on top of the silver base and will wear through over time, especially on high-contact surfaces like the inner band of a ring. Once the gold layer wears through, the silver beneath may tarnish more visibly. Re-plating (applying a fresh gold layer) is a service most jewellers offer, typically for $20–60 AUD depending on the piece size. Browse the Mowey rings collection and earrings collection for pieces that work well with either a re-polish or re-plate when they need refreshing after regular wear.
Frequently asked questions
How do I clean sterling silver jewellery at home?
The simplest method is warm water with a few drops of mild dish soap and a soft toothbrush. Soak the piece for 5–10 minutes, scrub gently, rinse thoroughly, and pat dry with a lint-free cloth. For light tarnish, a silver polishing cloth is even faster — just rub until the shine returns. For stubborn tarnish, a paste of baking soda and water works well: apply with a soft cloth, rub gently, then rinse and dry completely. Avoid using toothpaste or harsh chemicals, as these can scratch the surface.
How do I stop my silver jewellery from tarnishing?
Store silver in airtight bags or an anti-tarnish jewellery box when not wearing it. Put jewellery on after applying perfume and lotion, and remove before swimming or showering. After each wear, give pieces a quick wipe with a soft cloth to remove skin oils before storing. In humid climates, adding anti-tarnish strips to your jewellery storage slows the process noticeably. These habits together can keep sterling silver bright for months between polishes.
How long does sterling silver last?
Sterling silver jewellery can last decades with proper care. The metal itself doesn't degrade — tarnish is surface-level and easily removed. Physical wear such as scratches and dents is the main cause of long-term deterioration, and this can be addressed with professional polishing. Many well-cared-for sterling silver pieces outlast their owners. The key is consistent basic care: storing properly, keeping it dry, and polishing when needed.
Is it safe to clean silver with baking soda?
Yes — a paste of baking soda and water is a gentle, effective silver cleaner. Apply with a soft cloth, rub gently in small circular motions, then rinse well and dry completely. Avoid using baking soda on pieces with soft or porous gemstones such as pearls, opals, or turquoise, as the mild abrasive can scratch delicate surfaces. For pieces with gemstone settings, stick to warm soapy water and a soft toothbrush instead.
