  • Dish soap
  • Safety gloves

Safety Precautions

Prioritize safety when working with cleaning agents and your dishwasher. Always wear safety gloves to protect your hands. Additionally, ensure the dishwasher is unplugged or turned off at the circuit breaker.

Cleaning the Exterior

Start by cleaning the exterior of your Bosch dishwasher. Use a damp cloth and mild dish soap to wipe down the front, control panel, and door. Pay attention to any buttons or crevices where dirt may accumulate.

Cleaning the Interior

Step 1: Empty the Dishwasher

Before sanitizing the interior, remove all dishes, utensils, and racks from the dishwasher.

Step 2: Remove and Clean the Filter

Locate the dishwasher filter at the bottom of the interior. Remove it and rinse it thoroughly under warm running water. Use a small brush or toothbrush to remove any stubborn debris.

Step 3: Wipe Down the Interior

Using a soft cloth or sponge, wipe down the interior walls, including the door and the bottom. Ensure there is no food residue or grime left behind.

Step 4: Inspect the Spray Arms

Check the spray arms for clogs or debris. Remove any obstructions to ensure optimal water flow during the washing cycle.

Sanitizing the Dishwasher

Step 5: Vinegar Rinse

Pour one cup of white vinegar into a dishwasher-safe container and place it on the top rack of your dishwasher. Run a hot water cycle without any dishes. The vinegar will help remove mineral deposits and disinfect the interior.

Step 6: Baking Soda Scrub

Sprinkle a cup of baking soda on the bottom of the dishwasher. Run a short hot water cycle to distribute the baking soda evenly. This will help remove odors and stains.

Step 7: Hydrogen Peroxide Finish

To disinfect further, pour one cup of hydrogen peroxide into a dishwasher-safe container and place it on the top rack. Run another hot water cycle. Hydrogen peroxide is an excellent antibacterial agent.

Cleaning the Accessories

Don’t forget to clean the racks, utensil holder, and any other removable accessories. Soak them in warm, soapy water, scrub, and rinse thoroughly before placing them back in the dishwasher.
