How to Clean a Stainless Steel Dishwasher: A Comprehensive Guide

Cleaning your stainless steel dishwasher is vital for maintaining its performance, longevity, and ensuring your dishes emerge sparkling clean. The best approach involves a regular routine encompassing both surface cleaning and internal purification, using readily available household ingredients to eliminate food debris, hard water stains, and unpleasant odors.

Understanding the Importance of Cleaning Your Dishwasher

A dirty dishwasher isn’t just unsightly; it’s a breeding ground for bacteria and mold. Food particles accumulate, leading to unpleasant smells and potentially affecting the cleanliness of your dishes. Regular cleaning prevents clogs, ensures proper water flow, and maximizes the lifespan of your appliance. Neglecting this simple task can lead to costly repairs or even premature replacement. The shiny stainless steel exterior needs separate attention to prevent streaks and fingerprint build-up.

Step-by-Step Guide to Cleaning Your Stainless Steel Dishwasher

This comprehensive guide provides a detailed process for cleaning both the interior and exterior of your stainless steel dishwasher. Follow these steps for a sparkling clean and efficiently operating machine.

1. Gather Your Supplies

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

White vinegar
Baking soda
Dish soap (gentle)
Microfiber cloths
Soft-bristled brush or old toothbrush
Rubber gloves (optional)
Wooden skewer or toothpick

2. Empty the Dishwasher

Ensure your dishwasher is completely empty. Remove all dishes, utensils, and racks. Inspect the racks for any loose food particles or debris and remove them.

3. Clean the Filter

The dishwasher filter is a prime location for trapped food particles. It’s usually located at the bottom of the dishwasher.

Locate the filter assembly (refer to your dishwasher’s manual if needed).
Remove the filter by twisting or lifting it out.
Rinse the filter under warm running water to remove loose debris.
Use a soft-bristled brush or toothbrush to scrub away stubborn grime.
If the filter is heavily soiled, soak it in a solution of warm water and dish soap for 15-20 minutes.
Rinse thoroughly and replace the filter in its designated location, ensuring it’s securely in place.

4. Clean the Spray Arms

Dishwasher spray arms can become clogged with food particles and mineral deposits, hindering their ability to effectively clean dishes.

Detach the spray arms (consult your dishwasher manual for instructions).
Use a wooden skewer or toothpick to clear any clogs in the spray arm nozzles.
Rinse the spray arms under warm running water.
If the spray arms are heavily stained, soak them in a solution of warm water and white vinegar for 30 minutes.
Rinse thoroughly and reattach the spray arms to the dishwasher.

5. Clean the Dishwasher Interior with Vinegar

Vinegar is a natural disinfectant and excellent for removing hard water stains and mineral deposits.

Place a dishwasher-safe cup or bowl filled with one cup of white vinegar on the top rack of the empty dishwasher.
Run the dishwasher on the hottest cycle.
This will help to dissolve mineral deposits and freshen the dishwasher.

6. Clean the Dishwasher Interior with Baking Soda

Baking soda acts as a deodorizer and gentle abrasive cleaner.

Sprinkle one cup of baking soda on the bottom of the empty dishwasher.
Let it sit overnight.
Run a short, hot cycle to further freshen and clean the dishwasher.

7. Clean the Door and Gasket

The dishwasher door and gasket can trap food particles and mold, leading to unpleasant odors and potential leaks.

Wipe down the door interior and gasket with a damp cloth and dish soap.
Use a soft-bristled brush or toothbrush to scrub away any stubborn grime in the gasket folds.
Rinse thoroughly with a damp cloth.

8. Clean the Stainless Steel Exterior

The stainless steel exterior of your dishwasher requires specific care to prevent streaks and fingerprint buildup.

Mix a small amount of gentle dish soap with warm water.
Dip a microfiber cloth into the soapy water and wring out excess moisture.
Wipe down the stainless steel exterior, following the grain of the metal.
Rinse the cloth with clean water and wipe away any soap residue.
Dry the exterior with a clean, dry microfiber cloth to prevent water spots and streaks. For added shine, consider using a stainless steel cleaner specifically designed for appliances, always following the manufacturer’s instructions.

9. Preventing Future Buildup

Regular maintenance is key to preventing future buildup and keeping your dishwasher clean. Run a vinegar cycle monthly to help prevent mineral deposits and keep the dishwasher smelling fresh. Regularly inspect and clean the filter and spray arms.

Frequently Asked Questions (FAQs) About Cleaning Dishwashers

Here are some frequently asked questions about cleaning your stainless steel dishwasher:

1. How often should I clean my dishwasher?

It’s recommended to clean your dishwasher at least once a month. If you use your dishwasher frequently or notice buildup, you may need to clean it more often. The filter should be cleaned every one to two weeks.

2. Can I use bleach to clean my dishwasher?

While bleach can be effective for disinfecting, it’s not recommended for stainless steel dishwashers. Bleach can corrode stainless steel and damage the dishwasher’s components. Vinegar is a safer and more effective alternative.

3. What if my dishwasher still smells bad after cleaning?

If your dishwasher still smells bad after cleaning, double-check the filter and spray arms for any remaining debris. You can also try running a cycle with lemon juice or baking soda to further deodorize the dishwasher. Ensure the drain hose is properly connected and free of obstructions.

4. How do I remove hard water stains from my dishwasher?

White vinegar is excellent for removing hard water stains. Run a cycle with a cup of vinegar as described above, or use a commercial dishwasher cleaner specifically designed for hard water stains.

5. My dishwasher is leaking. Could cleaning help?

While cleaning can help prevent minor leaks caused by clogged filters or spray arms, more significant leaks may require professional repair. Ensure the door gasket is clean and properly sealed.

6. Can I use dishwasher detergent to clean the dishwasher?

No, you shouldn’t use regular dishwasher detergent to clean the dishwasher itself. It can leave behind residue and doesn’t have the same cleaning properties as vinegar or baking soda.

7. How do I clean the food disposal built into my dishwasher?

If your dishwasher has a built-in food disposal, refer to your dishwasher’s manual for specific cleaning instructions. Generally, you can run a cycle with a cup of white vinegar or a commercial dishwasher cleaner designed for disposals. Avoid putting large food scraps down the disposal.

8. What are those white spots on my dishes after washing?

White spots on your dishes are typically caused by hard water. Using a rinse aid can help prevent these spots. You can also add a cup of white vinegar to the bottom of the dishwasher before running a cycle.

9. How can I prevent my dishwasher from getting dirty in the first place?

Rinse dishes before loading them into the dishwasher. Regularly clean the filter and spray arms. Run a maintenance cycle with vinegar monthly. Avoid overloading the dishwasher.

10. How do I clean rust spots inside my dishwasher?

For rust spots, try using a paste of baking soda and water. Apply the paste to the rust spots, let it sit for a few minutes, and then scrub gently with a non-abrasive sponge. For more stubborn rust, consult a professional appliance repair technician.

11. What is the best way to dry the stainless steel exterior after cleaning?

Use a clean, dry microfiber cloth to thoroughly dry the stainless steel exterior immediately after cleaning. Drying in the direction of the grain helps to prevent streaks.

12. Are there any natural alternatives to commercial dishwasher cleaners?

Yes, white vinegar and baking soda are excellent natural alternatives to commercial dishwasher cleaners. They are effective, affordable, and environmentally friendly. Lemon juice can also be used as a natural deodorizer.

By following these steps and incorporating these tips into your cleaning routine, you can maintain a sparkling clean and efficiently operating stainless steel dishwasher for years to come. Regular cleaning is an investment in the longevity and performance of your appliance.
