Waterford Crystal suggests hand-washing your crystal one piece at a time in warm water with a light detergent. Avoid using scouring pads or harsh cleaners and instead use a soft cleaning cloth. Wipe away any residue with a dry, soft cloth. Do not put your crystal in the dishwasher or it may be damaged by the heat. Also, avoid spraying air fresheners into your crystal because chemicals found in some products can cause damage over time. If you want to give your crystal a thorough cleaning, remove all the glass from its container and wash each piece separately in hot soapy water. Rinse well in cold water and dry completely with a soft cloth. You should do regular maintenance tasks such as removing dust particles with a soft brush or feather duster. Use caution not to scratch or mark your crystal with hard objects. Waterford Crystal is guaranteed for life against defects in material and workmanship. The warranty covers manufacturing defects that cause pieces to break off or fall out of the setting. It also includes repair or replacement of lost parts, provided you have not altered or tampered with the item. Take care of your crystal and it will take care of you for many years to come.
