Keeping your crystal collection sparkling and pristine is key to having glassware that lasts. We recommend washing each piece by hand in warm water using a mild detergent and then drying the glasses with a lint-free cloth. When washing and drying, be mindful not to twist the bowl in the opposite direction of the stem. Although putting the glassware in the dishwasher may be tempting, it will ultimately dull or scratch the surface of your glasses. Extreme temperatures can also cause damage to crystal, so that's a hard no to hot liquids, the microwave, and the freezer. Finally, avoid storing or drying your glassware upside down, as the finely made rims are the most fragile part of your crystal glassware!
