Caring for Your Sterling Silver Jewellery. Silver should not come into contact with harsh household chemicals such as bleach, ammonia, or chlorine. To avoid scratches, store silver in a lined jewellery box or pouch, as it is prone to tarnish as it naturally reacts with sulphur or hydrogen sulphide in the air. Cleaning and wearing silver jewellery regularly will prevent this and help maintain its shine. Immediately upon noticing any discoloration, use a gentle polishing cloth made specifically for removing tarnish.
