Disinfect it: Pour vinegar into a dishwasher-safe cup, then place the cup upright on an empty dishwasher’s top rack. Run a full cycle, using the hot-water setting. Next, deodorize the machine by sprinkling a cup of baking soda on the bottom of the tub and running the dishwasher on a half-cycle with hot water. Leave your dishwasher door open for a few hours after to air it out.
When you see mold and mildew: Pour ½ to 1 cup of bleach into the bottom of the dishwasher and run a full cycle. For stainless-steel interiors, use vinegar and baking soda.
Clean: Once a month
