Silver will oxidize naturally, use a gentle silver cleanser or a silver polishing cloth to clean and re-shine as needed. Store your jewelry pieces in an airtight container or a ziplock bag whenever not in use to keep them from oxidizing quickly. You+Sterling Silver = Forever. The oils in your skin help keep silver from oxidizing fast. So, wear often.
