How do I remove spots and film from glasses and flatware?

Use Jet-Dry rinse agent to remove spots and prevent new film build-up. For stubborn spots, run the longest cycle without detergent or metal utensils, and after 18–22 minutes pour 2 cups of white vinegar into the bottom of the tub and allow the cycle to complete. If vinegar doesn't work, repeat using 1/4 cup of citric acid crystals instead. (Page 12)
