Cleaning

In common with ceramics, glassware should never be put in a dishwasher, as the salts and detergents may harm the surface and cause cloudiness. Wash glass carefully by hand in a plastic bowl with a towel or foam mat on the bottom. Use warm water and a little soap liquid and wash only one piece at a time. If the glass is very dirty or greasy, a few drops of household ammonia can be added to the water but not if the piece is gilded. Dry carefully and thoroughly while the glass is still warm using a lint -free cloth. A warm hair dryer can be used, well away from the sink and water, to dry the inside of decanters or other vessels or place them upside down in an airing cupboard for 24 hours. You can also roll up paper towel, push it into a decanter until it touches the bottom, being careful not to lose the end, and remove it 24 hours later.
