925 sterling silver jewelry tarnishes. This is normal — and easy to fix. This guide tells you exactly how to clean it, what to use, what to avoid, and how to slow down tarnishing in the first place.
Why Does 925 Silver Tarnish?
The 7.5% copper in 925 sterling silver reacts with sulfur compounds in the air and in your skin's natural oils. The result is silver sulfide — the dark gray or black patina that forms over time. This is not damage; it's chemistry. The underlying silver is completely intact. The tarnish is purely cosmetic and fully reversible.
What You'll Need
You probably have everything already:
- Soft-bristled toothbrush (or dedicated jewelry brush)
- Mild dish soap (original Dawn works well)
- Warm water
- Soft, lint-free cloth (microfiber or dedicated silver cloth)
- Small bowl
Step-by-Step Cleaning Process
- Mix a cleaning solution: Add a few drops of mild dish soap to a bowl of warm (not hot) water. Avoid boiling water — it can loosen stone settings.
- Soak for 5–10 minutes: Place the chain or bracelet in the solution. Soaking loosens oils, skin residue, and early-stage tarnish.
- Scrub gently: Use a soft toothbrush to work the soap solution into the links. Pay attention to crevices and the undersides of links where tarnish accumulates. For iced-out pieces with stone settings, brush carefully around the stones without pressing on them directly.
- Rinse thoroughly: Rinse under clean running water. Make sure all soap residue is removed — soap residue left on iced-out settings can dull the stone brilliance.
- Dry completely: Pat dry immediately with a soft cloth. Do not air-dry — water left in chain links accelerates tarnishing. For chains, lay flat on a towel and gently work moisture out of each link section.
- Buff to a shine: Use a dry silver polishing cloth (available at jewelry stores for $5–10) to bring up the final shine.
For Heavier Tarnish: Baking Soda Method
If the soap method doesn't remove deep tarnish:
- Mix baking soda and water into a paste (roughly 3:1 ratio)
- Apply gently with a soft cloth to the tarnished areas
- Rub in a back-and-forth motion (not circular — circular can create micro-scratches)
- Rinse thoroughly and dry completely
Do not use this method on pieces with opal stones, enamel, or soft gemstones — the abrasive action can scratch or damage them.
What to Avoid
- Ultrasonic cleaners — Can loosen prong settings and damage certain stones (opal, emerald, pearls)
- Bleach or chlorine — Chemically degrades silver
- Abrasive cleaners or steel wool — Will scratch the surface
- Toothpaste — Commonly suggested, but too abrasive for polished jewelry
- Paper towels — The fibers are coarser than they look; use microfiber or a dedicated cloth
How to Slow Down Tarnishing
- Store in an airtight pouch or sealed bag — Limits exposure to sulfur in air
- Add an anti-tarnish strip to your jewelry box — Absorbs sulfur compounds. Available for $5 for a pack of 10.
- Remove before showering and swimming
- Apply perfume and lotion before putting jewelry on
- Wipe with a dry cloth after each wear — Removes skin oils before they react with the silver
Your Bornreal chain or bracelet came with a jewelry pouch for exactly this purpose. Storing it in the pouch between wears is the single most effective thing you can do to extend the time between cleanings.
