How to Care for 925 Sterling Silver Jewellery: A Complete Guide
Why silver jewellery turns black: 925 silver contains 7.5% other metals (usually copper), and after exposure to sulfur, sweat, cosmetics or perfume in the air, the surface will vulcanize, resulting in a layer of black silver sulfide - this is a normal chemical phenomenon, not a quality problem, and can be recovered with a silver cloth. Nickel-free and lead-free 925 silver also oxidizes, with the difference that it does not irritate the skin.
Daily wear precautions: Bathing, swimming (chlorinated pool water is especially harsh on silver), sweating a lot in fitness, doing housework and contact with cleaning agents, it is recommended to remove jewellery; wear makeup and perfume before wearing; avoid spraying hairspray and sunscreen spray directly on the jewellery.
Household cleaning method: The safest way is to use warm soapy water and a soft brush. After gently brushing, rinse with clean water and then dry with a soft cloth. For stubborn oxidation, use a special silver cloth or silver paste to wipe in one direction. The styles with zirconium and jade do not need to soak the whole piece in water, just gently wipe it with a slightly damp soft cloth. Be careful not to use toothpaste - the abrasive particles inside will scratch the surface.
Storage: The most effective way is to put the jewellery separately in a sealed bag and squeeze out the air, isolating the air is the key to preventing oxidation; store different materials separately to avoid scratching each other; put a small packet of desiccant in the bag, do not put it in a damp bathroom or window for a long time.
Suggestions for stores and wholesalers: Avoid direct exposure to strong light for a long time when displaying, and open trays are prone to accumulation of ash; standard retail cards, independent antioxidant bags, and gift boxes can significantly reduce returns and exchanges and customer complaints; a maintenance card is included with the goods, the customer experience is good, and the repurchase rate will be higher.
When you need professional treatment: Do not wipe or straighten yourself when the gold-plated layer is worn out to remove gloss, serious oxidation blackening, deformation or breakage; the wholesale purchasing end can return directly to the factory for electroplating refurbishment, or supplement the new replacement display.
