Direct sunlight also causes silver to tarnish, so be sure to take off your silver jewelry before you go swimming and sunbathing. <span class="a-text-bold">Storage</span>: As exposure to air tarnishes it, storing silver in airtight plastic bags with anti-tarnish strips is a great preventative measure. <span class="a-text-bold">Polishing:</span> You can use a special silver cloth to polish your items, but a lint-free flannel, microfiber, or other soft nonabrasive cloth will do as well.
