How do I clean white residue from inside my dishwasher and dishes?

Monthly use of affresh® Dishwasher Cleaner is recommended to help remove white residue and maintain the dishwasher. Alternatively, place 2 cups (500 mL) white vinegar in a glass or dishwasher-safe container on the bottom rack and run a Normal wash cycle using an air-dry option without detergent. For hard water conditions, always use rinse aid and high-quality fresh detergent.
