Fortunately, cleaning a dishwasher from detergent buildup is a relatively simple task that can be done using household items. Here’s a comprehensive guide on how to clean dishwasher from detergent:

Gather Your Materials

Before you start cleaning, gather the following materials:

  • White vinegar
  • Baking soda
  • Lemon
  • Dish soap
  • Soft cloths or sponges
  • Toothbrush (optional)

Clean the Dishwasher Filter

1. Locate the dishwasher filter, which is typically found on the bottom of the dishwasher tub.
2. Remove the filter and rinse it thoroughly with hot water to remove any food debris or detergent residue.
3. If there is heavy buildup on the filter, soak it in a solution of white vinegar and water for 30 minutes before rinsing.

Clean the Detergent Dispenser

2. Remove the dispenser and soak it in a solution of white vinegar and water for 30 minutes.
3. Use a toothbrush to gently scrub away any stubborn detergent buildup.
4. Rinse the dispenser thoroughly with hot water and replace it in the dishwasher.

Run a Vinegar Cycle

1. Fill a dishwasher-safe cup with white vinegar and place it on the top rack of the dishwasher.
2. Run the dishwasher on a hot water cycle without any dishes or detergent.
3. The vinegar will help dissolve detergent buildup and deodorize the dishwasher.

Run a Baking Soda Cycle

1. Sprinkle 1 cup of baking soda on the bottom of the dishwasher tub.

3. Rinse the gasket thoroughly with clean water.

Clean the Spray Arms

2. Remove the spray arms and inspect them for any clogs or detergent buildup.
3. Use a toothpick or a small brush to gently remove any debris.
4. Rinse the spray arms thoroughly with hot water and replace them in the dishwasher.

Final Rinse

2. This will help rinse away any remaining detergent residue or cleaning solutions.

Tips for Preventing Detergent Buildup
