Yes, appliances designed to clean things actually need to be cleaned, too. Your automatic dishwasher needs a thorough cleaning once in a while to deodorize the inside and prevent your glassware and dishes from picking up an unpleasant odor. To clean your dishwasher, liberally sprinkle baking soda all over the interior. Then fill a large dishwasher-safe glass with white vinegar and place it right-side-up inside. Run it through a hot cycle (empty) to remove grease and grime and deodorize all in one run.
