How can I wash crystal and glass kitchenwares without scratch?
For hand wash, sponges which are especially manufactured for this purpose with soft surfaces must be preferred. Wash the dishes in warm water. Brightening can be done by adding a little amount of vinegar to rinse water. After washing, dry the dishes.
Do not overload the dishwasher and use suitable dish washing machine detergent. Place dishes in an orderly fashion. Dishes will have brighter and cleaner appearance if all of their surfaces contact with rinse aid or dryer even if they are placed anywhere on dishwasher shelf.
