We highly recommend the regular use of liquid rinse agent to give the best drying results. Rinse agent gives a streak free, sparkling clean look to glass and chinaware, in addition it prevents metal from tarnishing. The rinse agent dispenser is on the inside of the drawer, located underneath the detergent dispenser. The dispenser holds approximately 1.7 fl. oz. of rinse agent.

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

. 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.

Etching looks like rainbow colored film, as the glass is subjected to further washing the surface will eventually appear opaque. This type of etching is irreversible.

To prevent further etching from occurring on glassware use less detergent (follow the recommended detergent quantities in the User Guide for soft water situations), and ensure the dishwasher is not overloaded, so water can reach all the dishes during the wash.
