There is usually a box. In the back of a cupboard, wrapped in a tea towel that has not been washed since the nineties, holding a few things you inherited and never quite knew what to do with: a sugar bowl, a set of teaspoons, a photograph frame gone the colour of a storm cloud. October is the right month to deal with it, partly because the nights are long and this is satisfying work to do at the kitchen table, and partly because if you want any of it on a table in December, now is when it happens.
Tarnish is not dirt. It is a chemical reaction — silver meeting sulphur compounds in the air — and that distinction decides everything about how you treat it. Scrubbing harder does not remove tarnish faster; it removes silver.
Start with the gentlest thing that works
Before anything else, wash the piece in warm water with a drop of plain washing-up liquid, using your hands or a very soft cloth, then dry it completely. A surprising amount of what looks like tarnish is grease, dust and fingerprints, and you want a clean surface before you decide how bad the real problem is.
For light tarnish, a proper silver polishing cloth — the impregnated kind, not a random duster — is all you need. Work in straight lines rather than circles, with light pressure, and turn to a clean section of cloth as it blackens. For heavier tarnish, a dedicated silver polish applied with a cotton pad does the job; let it do the chemistry rather than leaning on it. Rinse and dry thoroughly afterwards, because polish residue left in crevices goes chalky.
The foil and bicarbonate trick — and when not to use it
You will have seen this one: line a bowl with aluminium foil, add hot water and a generous spoonful of bicarbonate of soda, submerge the silver so it touches the foil, and watch the tarnish lift within a minute or two. It genuinely works. It is an electrochemical swap rather than abrasion, so it does not wear the metal down, and it is brilliant for a drawer of blackened teaspoons.
But it is indiscriminate, and that is the catch. It will strip the deliberate dark shading out of engraved patterns, chased detail and oxidised jewellery — the shadow that makes a pattern readable. On an antique piece, that darkness is often the point, and once it is gone the object looks flat and oddly new. Keep this method for plain, utilitarian silver. Keep it away from anything with pearls, opals, turquoise, amber or glued-in stones, from hollow handles where water can get trapped and rot the filler, and from anything you would be heartbroken to change. If a piece is genuinely valuable or genuinely old, leave it alone and ask a professional restorer first.
What not to reach for
Toothpaste is the internet's favourite suggestion and a slow way to scratch things; most pastes are mildly abrasive and silver is soft. Avoid scouring cream, bleach, anything chlorine-based, and the dishwasher — the heat, the harsh detergent and the contact with stainless steel can pit and discolour silver, and it will wreck bone or wooden handles outright.
For silver jewellery with stones you cannot identify, use the cloth-and-nothing-else approach. For a plated piece that is wearing thin at the edges, be gentler still: there is only a skin of silver over base metal, and aggressive polishing removes it for good.
Why does my silver tarnish again so quickly?
Because of what is in the air and what it is touching. Rubber bands, wool, felt, newspaper and some woods all give off sulphur compounds, and so do eggs, onions, mustard and salt — which is why salt cellars and egg spoons blacken fastest. Wash silver promptly after it touches those foods rather than leaving it overnight, and store pieces in tarnish-resistant cloth bags or sealed plastic with the air pressed out, with a piece of chalk or an anti-tarnish strip tucked in to absorb moisture.
Should I use my silver or keep it put away?
Use it. Silver that is handled and washed regularly stays bright with almost no effort, because the gentle friction of use and washing-up keeps tarnish from building into a hard film. A canteen locked in a cupboard for a decade will need a serious session when you finally open it, whereas the teaspoons you actually stir your coffee with will look after themselves. There is also the quieter argument: a sugar bowl in a box is a possession, and a sugar bowl on the table on an ordinary Tuesday is a life.
