Does your dishwasher leave a white film on your clean dishes? It might not be your dishwasher’s fault. In 2010, phosphates were removed from most commercial dishwasher cleaners. In areas with hard water, this left dishwasher-cleaned dishes and glasses with a white film on the cleaned dishes due to minerals in the water.
To get rid of this, try adding a dishwasher booster like Lemi Shine. Lemi Shine removes tough water spots from dishes and glassware. Just add it to your regular dishwasher cleaner or else run your dishwasher with it alone on cleaned dishes to remove white film and hard water spots.
If this does not solve your white film problem try the following tips:
Make sure larger pots and pans are not blocking the spray arm spray in your dishwasher. Move these larger items to the side, away from the center.
Do not overload your dishwasher
Make sure you have the correct water temperature. The temperature of your hot water should be between 140-150 degrees Fahrenheit when it enters the dishwasher tub.
