Sterling Silver 925
To maintain the brilliant shine of your sterling silver jewelry, avoid any contact with water. While pure water does not damage 925 sterling silver, most water we encounter is not purified. To keep that shine intact, store your silver in an airtight bag or in a dry place. Silver is durable, but can be scratched if care is not taken. To polish it without scratching, use either a special jewelry or microfiber cloth.
Keep your brass jewelry wiped dry and in a dry spot. Storing brass jewelry either wrapped in an anti-tarnish cloth and/or an anti-tarnish bag is the best way to preserve its shine and quality.
If your jewelry is really tarnished, you can use a mix of baking soda, lemon juice and water. Scrub it on with a soft cloth or toothbrush, wipe off, and dry. And voilà, your jewelry is as new!
