After you have used the dishwasher cleaner/descaler you must run another wash program with detergent to prevent damage to the DishDrawer®.
Soft water situations
If you live in an area of naturally soft water or your household water is softened, avoid using too much detergent in your DishDrawer®. An excess amount of detergent is very aggressive on glassware and may cause irreversible etching.
Etching is a chemical deterioration that occurs on the surface of glassware when it is subjected to high temperatures, too much detergent and/or soft water situations. Etching is caused by a combination of very hot water, which causes the detergent to become very aggressive, but because the water is soft, there are no water hardness mineral ions for the detergent to bind to, so it extracts mineral ions directly from the glass.
