How to Clean Sterling Silver Jewellery at Home

Sterling silver tarnishes. That's not a defect — it's just what happens when silver reacts with sulphur in the air over time. The good news is that tarnish is only on the surface, and cleaning it off is easy with things you probably already have at home.

Why Does Sterling Silver Tarnish?

Sterling silver is 92.5% silver and 7.5% copper. Both metals react with sulphur compounds in the air, moisture, and even your skin's natural oils. The result is a dull, darkened surface — what jewellers call tarnish or patina.

Things that speed up tarnishing include humidity, perfume, hairspray, hand sanitiser, chlorine (pools and cleaning products), and leaving jewellery exposed to air for long periods.

The key thing to remember: tarnish doesn't mean your jewellery is damaged. It's a surface layer that cleans off easily.

Method 1: Silver Polishing Cloth (Best for Regular Use)

A silver polishing cloth is the simplest and safest way to keep sterling silver bright. These cloths are treated with a gentle polishing compound that removes tarnish without scratching.

How to use it: rub the piece gently in straight lines (not circles) until the tarnish lifts. That's it. Takes about 30 seconds per piece.

You can buy silver polishing cloths from most jewellers or online for a few euro. One cloth lasts for months.

This is the method we'd recommend for regular upkeep — do it once a week if you wear your pieces daily, or whenever you notice them looking dull.

Method 2: Warm Water and Washing-Up Liquid (For Everyday Dirt)

If your jewellery needs more than a quick polish — maybe it's been sitting in a drawer for a while, or it's picked up dirt and oils from daily wear — a simple soak works well.

What you need: a small bowl, warm water, a drop of mild washing-up liquid, a soft cloth or soft-bristle toothbrush.

1. Fill the bowl with warm (not hot) water and add a drop of washing-up liquid
2. Place your jewellery in the bowl and let it soak for 5–10 minutes
3. Gently brush any detailed or textured areas with a soft toothbrush
4. Rinse under clean running water
5. Pat dry immediately with a soft cloth — don't leave it wet

This won't remove heavy tarnish on its own, but it's perfect for cleaning off built-up grime and restoring some shine.

Method 3: Bicarbonate of Soda Paste (For Heavier Tarnish)

For pieces that have gone noticeably dark, a baking soda paste can bring them back.

What you need: bicarbonate of soda (baking soda), water, a soft cloth.

1. Mix 3 parts bicarbonate of soda with 1 part water to make a thick paste
2. Apply the paste to the tarnished areas with your fingers or a soft cloth
3. Rub gently in straight lines
4. Rinse thoroughly under running water
5. Dry completely with a soft cloth

Be gentle — baking soda is mildly abrasive, so don't scrub hard or use it on pieces with delicate stone settings or oxidised (intentionally darkened) finishes.

Method 4: Aluminium Foil and Boiling Water (For Badly Tarnished Pieces)

This is the "science experiment" method, and it works surprisingly well on heavily tarnished silver. It uses a chemical reaction to transfer the tarnish from the silver to the aluminium foil.

What you need: a heat-safe bowl or dish, aluminium foil, boiling water, 1 tablespoon of bicarbonate of soda, 1 tablespoon of salt.

1. Line the bowl with aluminium foil, shiny side up
2. Place your silver jewellery on the foil, making sure each piece touches the foil
3. Sprinkle the bicarbonate of soda and salt over the jewellery
4. Pour boiling water over everything until the pieces are fully submerged
5. You'll see fizzing — that's the reaction working
6. Leave for 2–5 minutes
7. Remove with tongs (it'll be hot), rinse under cool water, and dry with a soft cloth

This method should only be used for plain silver pieces — avoid it with pieces that have gemstones, pearls, or oxidised finishes, as the reaction can damage them.

How to Prevent Tarnish

Prevention is easier than cleaning. A few simple habits will keep your sterling silver looking good for much longer:

Store it properly. Keep pieces in a soft pouch, lined box, or ziplock bag when you're not wearing them. Reducing air exposure slows tarnishing dramatically.

Put jewellery on last. Apply perfume, hairspray, moisturiser, and hand sanitiser before putting on your jewellery. These products accelerate tarnishing.

Take it off for water activities. Remove sterling silver before swimming, showering, or washing dishes. Chlorine and prolonged moisture are the biggest offenders.

Wear it. This might sound backwards, but the natural oils on your skin can actually help keep sterling silver polished through regular contact. Pieces that sit unworn in drawers tarnish faster than pieces you wear regularly.

What NOT to Use

Avoid toothpaste (despite what the internet says — it's too abrasive and can scratch), bleach, ammonia-based cleaners, and any harsh chemical cleaning products. These can damage the surface of sterling silver permanently.

Also avoid ultrasonic cleaners unless you're certain your piece has no gemstones, glued settings, or delicate elements.
