Tarnish is normal for silver. With the right storage and gentle cleaning, it’s easy to keep under control.
What to remember
- Silver tarnishes when it reacts with sulfur compounds in the air, which forms a dark film on the surface.
- Under FTC guidance, sterling silver contains 92.5% pure silver, often marked 925.
- Storing silver in a closed pouch or box, away from humidity, slows tarnish.
- A silver polishing cloth removes light tarnish; avoid harsh abrasives, especially on plated pieces.
If you own silver jewelry, you’ve probably seen it darken over time. That’s tarnish, and it’s a normal reaction rather than a sign of poor quality.
What causes tarnish
Silver reacts with sulfur compounds in the air, forming a thin dark layer of silver sulfide on the surface. Humidity, household chemicals, some foods and even certain fabrics and papers can speed it up.
Sterling, plated and coated silver
| Type | What it is | Care |
|---|---|---|
| Sterling silver (925) | 92.5% pure silver, according to the FTC | Polish gently; tarnish can be removed |
| Silver-plated | A thin silver layer over another metal | Polish very gently; plating can wear through |
| Rhodium-plated silver | Sterling coated with rhodium | Resists tarnish until the coating wears |
The FTC notes that the terms “silver,” “sterling” and “sterling silver” are used for products containing 92.5% pure silver, and that a “925” mark means 925 parts in every 1,000 are silver.
Preventing tarnish
- Store silver in a closed pouch, zip-top bag or lined box.
- Add an anti-tarnish strip to your jewelry box.
- Keep silver away from bathrooms and other humid places.
- Put silver on after lotion, perfume and hair spray.
- Wear it often; regular wear and wiping slow tarnish.
Buying tip: Wipe silver with a soft cloth after each wear before putting it away. It removes skin oils and moisture that speed up tarnish.
Cleaning tarnished silver
For light tarnish, a silver polishing cloth is usually enough. For heavier tarnish, wash the piece in warm water with a little mild dish soap, dry it thoroughly, then polish. Avoid abrasive pastes on plated pieces, as they can remove the thin silver layer.
Before you buy: Silver set with pearls, opals or other sensitive gems needs extra care. Avoid dips and chemicals, and see our guides to pearl care and cleaning jewelry at home.
A little and often
Silver is easiest to care for when you never let tarnish build up. A quick wipe after wearing and closed storage will keep most pieces looking bright for years.
Common jewelry questions
Does tarnish mean my silver is fake?
No. Real silver tarnishes naturally. Sterling silver usually tarnishes more noticeably than pieces with a protective coating, such as rhodium plating.
Can I wear silver in the shower?
It’s best not to. Soaps, shampoos and chlorinated water can speed up tarnish and leave a dull film.
Why is my silver ring turning my finger green or dark?
Metals in the alloy, including copper, can react with moisture and skin. Keeping the ring clean and dry usually helps.
