How to Clean a Dishwasher

A dishwasher is a kitchen appliance that plays a crucial role in maintaining the cleanliness of your dishes. However, over time, it’s not uncommon for dishwashers to accumulate dirt, grease, and mineral deposits, leading to unpleasant odors and reduced efficiency. To ensure your dishwasher continues to function optimally and keeps your dishes sparkling clean, regular cleaning is essential. In this comprehensive guide, we’ll walk you through the step-by-step process of how to clean a dishwasher effectively.

How to Clean a Dishwasher

Gather Your Supplies:

Before you begin the cleaning process, gather the necessary supplies. You’ll need:

• White vinegar
• Baking soda
• Dish soap
• Toothbrush or small scrub brush
• Microfiber cloth
• Toothpick or similar small, pointed object

Having these items on hand will make the cleaning process more efficient.

Empty the Dishwasher:

Start by emptying the dishwasher completely. Remove any dishes, utensils, and racks to access all the nooks and crannies.

Inspect the Drain

The dishwasher drain is a common area for food particles and debris to accumulate. Check the drain for any visible obstructions. Use a toothpick or a similar small, pointed object to dislodge any clogs.

Clean the Filter

Most dishwashers have a filter that traps larger food particles. Locate the filter (refer to your dishwasher’s manual if needed), remove it, and clean it thoroughly. Rinse the filter under warm water to remove any stubborn residue.

Wipe Down the Interior

Dampen a microfiber cloth with a mixture of equal parts water and white vinegar. Wipe down the interior of the dishwasher, paying special attention to the door, gaskets, and edges. Vinegar is effective in breaking down grease and removing mineral deposits.

Clean the Spray Arms

Dishwasher spray arms can become clogged with food particles and mineral deposits. Remove the spray arms according to your dishwasher’s manual and soak them in a solution of white vinegar and water. Use a toothbrush or a small scrub brush to clean the spray arm nozzles thoroughly.

Descale with Baking Soda

To remove mineral deposits and hard water stains, sprinkle a cup of baking soda on the bottom of the dishwasher. Run a short, hot water cycle to allow the baking soda to break down and remove the deposits. Baking soda is a natural and gentle abrasive that helps in cleaning without causing damage.

Run a Vinegar Cycle

Place a dishwasher-safe container filled with white vinegar on the top rack of the dishwasher. Run a hot water cycle without any dishes. The vinegar will help dissolve any remaining mineral deposits, eliminate odors, and sanitize the interior of the dishwasher.

Clean the Exterior

Don’t forget to clean the exterior of your dishwasher. Wipe down the control panel, buttons, and handles with a damp cloth. For stainless steel exteriors, use a stainless steel cleaner to maintain a polished and streak-free appearance.

Check the Door Seal

Inspect the rubber door seal for any signs of mold, mildew, or debris. Wipe it down with a mixture of water and mild dish soap. If mold is present, consider using a mixture of water and hydrogen peroxide to kill the mold and prevent it from returning.

Additional Tips

Here are some additional tips to enhance your dishwasher cleaning routine and maintain optimal performance:

1. Regular Maintenance Schedule:
   • Establish a routine for dishwasher maintenance. Performing cleaning tasks on a regular schedule, such as once a month, can help prevent the buildup of grime and deposits.
2. Pre-Rinse Dishes:
   • While modern dishwashers are designed to handle dirty dishes, a quick pre-rinse can help prevent large food particles from clogging the filter and spray arms. Scrape off excess food before loading the dishes.
3. Remove and Clean Spray Arms:
   • Periodically remove the dishwasher spray arms according to your manual’s instructions. Inspect and clean the nozzles to ensure proper water flow, which is crucial for effective cleaning.
4. Check Water Temperature:
   • Verify that your dishwasher is receiving hot water. The recommended water temperature for optimal cleaning is typically around 120°F (49°C). Hot water helps dissolve detergents and ensures effective stain removal.
5. Use the Right Detergent:
   • Choose a high-quality dishwasher detergent that is suitable for your water hardness level. Follow the manufacturer’s recommendations on the detergent packaging for the correct amount to use.
6. Run Full Loads:
   • Dishwashers are most efficient when running full loads. This not only conserves water and energy but also provides better cleaning results.
7. Run an Empty Cycle:
   • Periodically run an empty dishwasher cycle with a cup of white vinegar on the top rack. This helps to clean and deodorize the dishwasher, as well as prevent mineral buildup.
8. Inspect and Clean the Inlet Valve:
   • Check the dishwasher’s inlet valve for any sediment or debris buildup. If your water supply has high mineral content, consider installing a water softener or using a dishwasher cleaner that targets hard water deposits.

Products You Can Buy

In South Africa, you can find various cleaning products suitable for maintaining and cleaning your dishwasher. Here are some common products you can consider:

1. White Vinegar:
   • White vinegar is an excellent natural cleaner that helps break down grease, eliminate odors, and remove mineral deposits. You can use it to clean the interior of the dishwasher, including the spray arms and filter.
2. Baking Soda:
   • Baking soda is a gentle abrasive that can help remove stains and deposits from the dishwasher. It’s particularly useful for descaling and deodorizing. Sprinkle baking soda on the dishwasher floor before running a short, hot water cycle.
3. Dishwasher Cleaner Tablets:
   • Many brands offer dishwasher cleaner tablets specifically designed to remove limescale, grease, and odors. These tablets often come in convenient single-use packs, making them easy to use.
4. Citric Acid:
   • Citric acid is effective in breaking down mineral deposits and limescale. You can use it similarly to vinegar, either by adding it to the dishwasher during a cycle or by running a separate cycle with a citric acid solution.
5. Dish Soap:
   • Mild dish soap can be used to clean the exterior of the dishwasher, including the control panel, buttons, and handles. Mix a small amount of dish soap with water and use a cloth to wipe down these surfaces.
6. Rinse Aid:
   • Rinse aid helps to improve drying performance and prevents mineral deposits on dishes and the dishwasher interior. It’s a liquid solution that you can add to the designated compartment in your dishwasher.
7. Microfiber Cloths or Sponges:
   • These are useful for wiping down the interior and exterior of the dishwasher. Microfiber cloths are particularly effective for capturing and removing dirt and grime without scratching surfaces.
8. Hydrogen Peroxide:
   • Hydrogen peroxide can be used to tackle mold or mildew on the rubber door seal. Mix it with water, apply it to the affected areas, and scrub with a soft brush.
9. Toothbrush or Small Scrub Brush:
   • A toothbrush or a small scrub brush can be handy for cleaning hard-to-reach areas, such as the nozzles on the spray arms or the corners of the dishwasher.
10. Rubber Gloves:
    • When using cleaning agents, especially if you’re using stronger solutions, wearing rubber gloves can protect your hands.
