Silver should be kept absolutely dry. If your silver is used frequently, keep it away from excessive exposure to air and store it in a tarnish-proof cloth, such as the flannel pouch provided with your Tiffany Co. silver, or a silver storage box. Good storage boxes are lined with tarnish-proof fabric and have a separate space for each individual piece. If your climate is humid, place a small packet of desiccant crystals inside your storage area, whether it is a closed box or a flannel roll. Avoid contact with rubber bands or other rubber products. The sulfur in rubber causes tarnishing and corrosion.
