It is recommended Crystal should be washed by hand in a plastic bowl of warm soapy water using a mild detergent - to minimize the risk of damage, items should be washed one at a time.
After washing the items should be rinsed in clean warm water and then placed on a drainer.
Dry the Crystal while still warm with a soft, dry cloth, taking care to always hold the outside of the bowl when drying a wine glass; never hold the foot while drying the bowl as this can easily lead to the bowl being twisted off and broken.
