Dishwashers are a modern-day marvel that saves us time and effort. However, like any other appliance, they require regular maintenance to function optimally. You might think that a machine designed to clean doesn’t need cleaning itself, but that’s a common misconception. In this guide, we’ll walk you through 10 expert tips to clean and descale your dishwasher, ensuring it runs smoothly and efficiently.

Why Clean Your Dishwasher?

You may wonder why a machine that uses hot water and detergent needs cleaning. The answer is simple: over time, food particles, grease, and soap scum can accumulate in various parts of the dishwasher, leading to unpleasant odors and reduced efficiency. Regular cleaning prevents costly repairs and ensures your dishes come out sparkling clean.

How Often Should You Clean Your Dishwasher?

  • Daily: Remove food particles after each cycle.
  • Weekly: Clean the filter.
  • Quarterly: Deep clean the interior.

Tools and Materials You’ll Need

  • White vinegar is a natural cleaner and descaler.
  • Dish Soap to remove grease and grime
  • Baking Soda is a natural abrasive cleaner.
  • Cleaning Cloth For wiping down surfaces
  • Spray Bottle For applying cleaning solutions
  • Toothbrush or Bottle Brush  For scrubbing hard-to-reach areas.

Step-by-Step Cleaning Guide

1. Unplug and Remove Racks

Safety first! Unplug your dishwasher and remove the lower and upper racks.

2. Wipe Down the Racks

Dampen a cloth with a mixture of vinegar, dish soap, and water. Wipe down both racks to remove hard water stains.

3. Clean the Filter and Floor

Locate the filter at the bottom of the built in dishwasher. Remove it and clean it under running water using a bottle brush or toothbrush.

4. Tackle the Spray Arms

Use a wire to unclog the holes in the spray arms. This removes any food particles or mineral deposits.

5. Clean the Interior Door

Spray a mixture of vinegar and water on the interior door and let it sit for 10 minutes. Wipe it down afterward.

6. Pay Attention to the Rubber Gasket

Use a toothbrush to remove particles and grime from the rubber gasket that seals the machine.

7. Clean the Front and Sides

Wipe down the front and sides of the dishwasher, avoiding any buttons or settings.

8. Utilize Magnetic Hooks

Place magnetic hooks on the side of the dishwasher to hang and store things like cleaning rags.

9. Don’t Forget the Cutlery Stand

Give the cutlery stand a good scrub and rinse.

10. Clean the Stand (If You Have One)

If your dishwasher is placed on a stand, don’t forget to clean it as well.

Descaling Your Dishwasher

Place a bowl of vinegar on the top rack and run the machine on the hottest and longest cycle. However, since vinegar is acidic, don’t do this too often.

Maintenance Tips

  • Always remove food particles after each cycle.
  • Open the dishwasher slightly after each cycle to let water vapor evaporate.
  • Check for drain blocks periodically.


Cleaning your dishwasher is not just a routine task but an investment in the longevity and efficiency of your appliance. With the right tools and a systematic approach, you can ensure that your dishwasher remains in peak condition, saving you time and money in the long run. So, roll up your sleeves and give your dishwasher the TLC it deserves—you won’t regret it!
