Jewelry care depends on the metal, gemstones, settings and any treatments in a piece. Do not assume that a cleaning method suitable for one item is suitable for another. For an unfamiliar or valuable piece, ask its maker or a qualified jeweler for care instructions.
Can you clean jewelry with hydrogen peroxide?
This article does not recommend a universal hydrogen peroxide treatment for jewelry. Check the jewelry maker’s instructions and the cleaning product’s label before choosing a method. Cleaning a piece is not the same as establishing that it has been sterilized.
Do not mix cleaning chemicals
Do not mix hydrogen peroxide with vinegar: the combination can form corrosive peracetic acid. Do not combine hydrogen peroxide with Windex or another household cleaning product. Do not substitute a different homemade mixture for the recipes previously published on this page.
Treat delicate and older pieces cautiously
Chemicals can damage or discolor precious metals and some gemstones. Gemstone treatments can also affect appropriate care. Costume jewelry, older pieces and items with unknown materials should be assessed before applying a chemical cleaner.
Avoid harsh chemicals such as chlorine bleach. Avoid abrasive scrubbing, and do not use a cleaning method that could loosen a setting. A qualified jeweler can check the condition of a piece and recommend a suitable method.
Caring for rings between cleanings
Remove rings before work that could strike or damage them and before handling household cleaners. Keep cosmetics and lotions away from delicate gems. Ask a jeweler about inspections and a maintenance schedule appropriate to the item; this page does not prescribe a peroxide-soaking schedule.
Piercing jewelry
Do not apply hydrogen peroxide directly to skin as part of jewelry cleaning. For piercing aftercare or concerns about irritation, seek advice from an appropriate professional rather than relying on a jewelry-cleaning article.
