Wash your crystal by hand with hand hot water, a soft sponge and mild dish detergent. Avoid extreme water temperatures and soaps containing ammonia. Wash your crystal as soon as possible after use and do not leave water standing in crystal for more than a few days. In flower vases make sure the water is refreshed and the glass is cleaned regularly. This is especially important in hard water areas as elements in the water can bite into the crystal and leave permanent water marks. Never put your crystal in the dishwasher as the detergents can permanently mark the crystal. Limescale build up can be cleaned with vinegar and or lemon,
Dry your crystal immediately after washing it and use a linen or lint-free cloth.
When drying stemware avoid holding the glass by the stem and twisting while drying the bowl of the glass as the weakest part of your stemware is the place where the bowl joins the stem. Instead, hold the bowl of the glass gently in your palm while drying the inside of the glass.
Store your crystal in a safe, dust-free area. Do not store your crystal glasses upside-down in the cupboard: The lip of the glass is very delicate and it may begin to crack under the weight of the glass.
Special care: If you have left your stemware out too long and dust, grime or stains have built up, try holding the pieces over a home steamer or a pot of boiling water until the build-up loosens, and then gently wash them with a soft sponge and very mild detergent. Be careful not to burn your hands while holding your stemware over the hot steam. You may want to wear an oven mitt to protect your hand from potential burns.
