Does Sterling Silver
Tarnish?
Why it happens, what speeds it up, and how to stop it and clean it.
You put on a sterling silver ring that was bright last month and it has gone grey. Nothing is wrong with it. Tarnish is what real silver does, and it is easy to slow down and to remove. This guide explains why 925 sterling silver jewellery tarnishes, what speeds it up and exactly how to clean and store it.
The quick answer
- ✔ Silver tarnishes when it reacts with sulphur in the air, on your skin and in everyday products
- ✔ Tarnish is normal for real silver and easy to remove
- ✔ Slow it down by wearing it often, storing it airtight and wiping it after wear
- ✔ Clean it with a silver polishing cloth or mild soapy water
- ✔ Stainless steel does not tarnish, so it suits daily wear

Why Does Sterling Silver Tarnish?
Sterling silver is 92.5% silver and 7.5% other metals, usually copper. Silver reacts with traces of sulphur compounds in the air to form silver sulphide, a thin dark layer. Copper in the alloy can darken too. The reaction is faster in humid air, around wool, rubber and eggs, and on skin that sweats more.
Tarnish is not a sign of fake silver. But it is not proof of real silver either, so use the 925 mark and our guide to identifying genuine 925 silver if you want to be sure. Read 925 vs S925 vs 999 silver for what hallmarks mean, or test other metals with our jewellery metal testing guide.
Seven Things That Make Silver Tarnish Faster
Humidity
Damp bathrooms speed up tarnish. Store silver somewhere dry.
Chlorine
Pools and hot tubs dull silver quickly. Take it off first.
Perfume and creams
Apply them first, then put your silver on.
Wool and rubber
Both release sulphur. Do not store silver against them.
Eggs and some foods
Sulphur in eggs and onions marks silver. Remove rings when cooking.
Sweat
Skin chemistry varies, so the same ring can tarnish faster on one person.
Open air
A ring left on a dressing table tarnishes faster than one sealed in a bag.
Want a metal that never needs polishing?
Stainless steel does not tarnish. Many people wear steel every day and keep silver for special pieces.
How to Prevent Tarnish on Silver Jewellery
- Wear it. The natural oils on your skin help protect silver, so a ring worn often tarnishes less than one in a drawer.
- Wipe it after wear. A soft dry cloth removes sweat and skin products before they react.
- Store it airtight. Use a small zip bag or lidded box with an anti-tarnish strip, one piece per bag so pieces do not scratch each other.
- Keep it dry. Never store silver in the bathroom.
- Put it on last. Perfume, hairspray and lotion go on first.
How to Clean Tarnished Sterling Silver
Light tarnish: rub with a silver polishing cloth until the dark marks lift. This is the safest method for any silver piece.
Moderate tarnish: wash in warm water with a drop of mild washing-up liquid, rinse and dry fully with a soft cloth.
Heavy tarnish on plain silver: line a bowl with foil, add hot water and a spoonful of baking soda, and rest the silver on the foil for a few minutes. Rinse and dry well. Do not use this on pieces with pearls, glued stones or an intentionally darkened (oxidised) finish.
Avoid toothpaste and harsh scouring powders. They are abrasive and leave fine scratches. Our 925 silver care card has the short version, silver-plated copper has its own card, and JewelCare™ covers every metal.
How a Silver Care Kit Helps Slow Oxidation
Oxidation is the everyday word for tarnish: silver reacting with gases in the air. A care kit tackles it from both sides. It slows tarnish while your silver is stored, and it lifts the first light marks before they set.
- Anti-tarnish strips. A zip bag on its own traps humidity and tarnish gases with your silver. Sealed with a strip inside, the same bag becomes proper tarnish-slowing storage. Write the date on the strip and replace it about every 3 months.
- Zip bags. One piece per bag keeps air and damp away and stops pieces scratching each other.
- Polishing cloth. Buff with short strokes to lift light tarnish early, before it builds up. Never wash the cloth.
One note: do not seal pearls, opal, turquoise, coral or enamel pieces in a bag with a strip. The cloth is also safe on stainless steel.

FAQs
Is tarnished silver fake?
No. Tarnish happens to real sterling silver. A genuine piece should carry a 925 mark. See our 925 vs S925 guide.
How quickly does sterling silver tarnish?
It depends on humidity, skin chemistry and storage. Some people see a change in weeks, others in many months. Wearing and airtight storage both slow it down.
Does silver tarnish if you wear it every day?
It tarnishes more slowly, because skin oils protect it and constant wear keeps it polished. Remove it before swimming, cleaning and cooking.
Can tarnish damage silver?
Light tarnish is only a surface layer and polishes off. Leaving heavy tarnish for years makes cleaning harder, so clean it early.
Is stainless steel better if I do not want to polish?
Yes. Stainless steel does not tarnish. Read our stainless steel vs sterling silver guide to choose, or shop stainless steel jewellery.
Does silver plating stop tarnish?
Plating such as rhodium can slow it, but plating wears with use. Read how sterling silver compares with silver-plated jewellery.
Does zinc alloy jewellery tarnish too?
It can, depending on the finish. See does zinc alloy jewellery tarnish? for what to expect.
