Why do glasses turn cloudy or develop film after dishwasher cycles?
When the issue appears to be film
Review detergent type and quantity, loading, spray access and the model's rinse-aid directions. Whirlpool's guidance treats these as relevant to deposits and washing performance. Follow the product and appliance instructions together; a detergent pack does not automatically remove the need to check the rinse-aid setting. Do not use hand-dishwashing liquid in the machine.
