How to Clean Silver Jewellery and Keep Tarnish Away

Silver has one predictable enemy: time plus air. Leave a sterling piece unworn for a few months and it returns darker, duller, vaguely neglected. That darkness is not dirt, and it is not damage. It is tarnish, and removing it is easy once you know how. Here is how to clean silver jewellery properly and, better, how to slow tarnish down in the first place.

What tarnish actually is

Tarnish is a thin dark layer that forms on the surface of silver, and it consists mainly of black silver sulphide. It forms when sulphur-containing compounds in the air, including traces of hydrogen sulphide, react with the metal. Sterling silver is an alloy of 92.5 per cent pure silver, stamped 925, and its small share of other metals makes the reaction a little more eager. The key point: tarnish is a surface film, not corrosion eating into the piece. It comes off.

The gentle routine clean

For dust, residue and light tarnish, warm water and dish soap are enough. Add two or three drops of washing-up liquid to a bowl of warm water, soak the piece for up to ten minutes, then rinse and dry thoroughly with a microfibre cloth. Skip paper towels and coarse fabrics, which can scratch. This mild wash handles most of what daily life deposits, and it is safe for nearly everything, including pieces set with gemstones, though porous stones prefer a quicker dip and no soaking.

Deeper fixes for heavy tarnish

When the wash is not enough, step up carefully. A paste of baking soda and water, rubbed gently with a soft cloth, lifts stubborn film. A proper silver polishing cloth, impregnated with a mild cleaner, restores shine with control. Chemical dips work fast, but treat them with respect: they can over-clean engraved or embossed detail, stripping the deliberate shading that gives patterned silver its depth. Whatever the method, check first whether the piece is solid sterling or silver plated, because plated pieces have only a thin skin of silver and aggressive cleaning can wear straight through it.

Why less polishing is more

Here is the conservator's secret: every polish removes a tiny amount of silver along with the tarnish. Museums avoid frequent tarnish removal for exactly this reason and focus instead on prevention. Your jewellery deserves the same logic. Clean when the piece needs it, not on a rigid schedule, and put your energy into storage that keeps tarnish from forming at all.

Storage that prevents tarnish

Tarnish needs sulphur and air, so starve it of both. Store silver in sealed bags or a closed box, ideally with anti-tarnish strips or a piece of chalk or silica gel to absorb moisture. Keep pieces apart so chains do not scratch softer surfaces. And mind the sulphur sources around the house: rubber bands, wool felt, and even eggs and onions in the kitchen release the compounds silver hates. A piece stored well can stay bright for years; a piece stored badly will need yet another polish, and polish is the one thing to ration.
