William Yeoward Crystal is a hand made product and although it is robust, care should be taken in its use, cleaning and storage.It is recommended Crystal should be washed by hand in a plastic bowl of warm soapy water using a mild detergent - to minimise 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
