If you notice black stuff or residue in your dishwasher, it is important to address it promptly to ensure proper functioning and cleanliness. Here's a step-by-step guide on how to clean a dishwasher with black residue:
Empty the dishwasher: Remove all dishes, racks, and utensil holders from the dishwasher. Ensure that the dishwasher is completely empty before proceeding with the cleaning process.
Check the drain filter: The black residue could be a result of clogged or dirty drain filters. Locate the drain filter at the bottom of the dishwasher and inspect it for debris or buildup. Clean or replace the filter as needed according to the manufacturer's instructions.
Wipe down the interior: Use a damp cloth or sponge to wipe down the interior surfaces of the dishwasher, including the walls, door, and floor. Pay extra attention to any areas with visible black residue, scrubbing gently to remove it.
Clean the spray arms: The spray arms in the dishwasher can accumulate residue and debris over time. Remove the spray arms according to the manufacturer's instructions and rinse them under running water. Use a soft brush or toothbrush to clean any clogged nozzles or openings.
Vinegar or citric acid wash: Fill a dishwasher-safe bowl or cup with white vinegar or citric acid (such as powdered citric acid or lemon juice). Place it on the top rack of the empty dishwasher. Run a hot water cycle on the dishwasher, selecting a heavy-duty or sanitizing cycle if available. The vinegar or citric acid will help remove the black residue and eliminate any odors.
Baking soda scrub: After the vinegar or citric acid wash, sprinkle a cup of baking soda across the bottom of the dishwasher. Run a short hot water cycle to further clean and deodorize the dishwasher. Baking soda helps to eliminate any remaining odors and can aid in removing stains.
Final wipe down: Once the dishwasher cycle is complete, use a clean cloth or sponge to wipe down the interior surfaces once again, ensuring that any remaining residue or cleaning agents are removed.
Regular maintenance: To prevent future buildup and maintain a clean dishwasher, consider performing regular maintenance tasks such as running empty dishwasher cycles with a dishwasher cleaner or descaler, and regularly cleaning the filter and spray arms.
Remember to consult your dishwasher's user manual for specific cleaning instructions and recommendations from the manufacturer.
