Crystal glassware can be washed both by hand and dishwasher. To hand-wash, add dishwashing liquid to warm water, and always ensure that the wash and rinse water are the same temperature. After cleaning, place glasses upside down on a towel for air drying. When washing crystal stemware, always hold the glass by the bowl, never by the stem, and do not twist the bowl and the stem in opposite directions when washing or drying.
For tough dirt, soak the glassware in water with a squirt of dishwashing liquid and 1/2 teaspoon of fabric softener, and leave overnight.
Avoid streaking by adding 1 tablespoon of vinegar or isopropyl (rubbing) alcohol to the rinse water. For extra shine, steam over boiling water and polish with a microfibre cloth. This will ensure that your crystal is always a show-stopping addition to any dinner party, event or even just your well-deserved evening relaxation.
