How to Clean Your Dishwasher

Sorry, your dishwasher doesn’t clean itself. Cleaning an appliance that’s in charge of cleaning may seem odd, but it’s necessary. Over time, food scraps, mineral deposits and soap scum build up inside the dishwasher and contaminate your clean dishes or reduce the efficiency of the unit. For extra-clean dishes and a long-lasting dishwasher, follow these cleaning tips.

How to Clean a Dishwasher in 10 Steps

Our dishwashers save us a lot of time and don’t ask for much, besides more dirty dishes. Return the favor and give your dishwasher a good deep clean. Cleaning a dishwasher is easy. It shouldn’t take you any longer than 30 minutes (not including run time) and doesn’t require any special cleaning supplies.

1. Clean the outside with soap, water and soft sponge. If your dishwasher has a stainless-steel finish, use a special cleaning product to avoid streaks. You can use a toothbrush to clean in between control knobs, on and around buttons and hard-to-reach areas.
2. Remove the racks and silverware holders, and hand wash in the sink as you would any dish.
3. Check the tub area at the bottom, and remove any debris with paper towel.
4. Scrub the spray arms with a stiff brush and soapy water. Remove mineral deposits on the water outlets or spray arms with a brush dipped in vinegar. Use a toothpick to clean out small orifices.
5. Some dishwashers have a food trap or filter. Follow the manufacturer’s directions to ensure the food trap is cleared out. You may need to unscrew or remove a cover. Many service manuals are available online.
6. Clean the rubber gasket on the door and perimeter with hot, soapy water. If you see mold or mildew, make a mild bleach solution with one tablespoon of bleach and a half gallon of warm water. Use a stiff brush to scrub the seal with this solution, and then rinse with fresh water.
7. Replace the racks and silverware holders.
8. Place a dishwasher-safe cup on the top rack, and fill it with white vinegar. Run the dishwasher through a full hot cycle.
9. After the steam and some of the heat has cleared, dry the inside with a thick towel (to avoid burning yourself and to wipe stuck-on grime).
10. Sprinkle a thin layer of baking soda all over the bottom of the dishwasher, and run it again on hot. Pro tip: Putting a spoonful of unsweetened, powdered lemonade mix in the soap container makes this step smell great.
