How do I clean the interior of the dishwasher and remove white spots or film?

Clean the cooled-down interior with a paste of powdered dishwasher detergent and water, or use liquid dishwasher detergent on a damp sponge. To remove white spots and film, place 2 cups (500 mL) of white vinegar in a glass or dishwasher-safe measuring cup on the bottom rack and run a complete washing cycle using an air-dry or energy-saving dry option without detergent. Be cautious not to use vinegar too often, as it is an acid that could damage the dishwasher over time. (Page 9)
