- Make sure the dishwasher is completely empty.
- Fill a heat-safe bowl with 1–2 cups of white vinegar and set it on the top rack.
- Sprinkle a few tablespoons of baking soda across the bottom of the machine.
- Run a full hot cycle, letting the steam carry the vinegar and baking soda into every corner.
- Open the door afterward and let everything air dry.
The heat helps the vinegar dissolve grease and mineral deposits while the baking soda scrubs gently and absorbs odor at the same time. It’s a simple combination, but it reaches the spray arms, tubing, and corners that are impossible to scrub by hand.
