A dishwasher is an invaluable appliance in any modern kitchen, but a persistent smell emanating from it can quickly turn it into a nuisance. If you’re struggling with how to get rid of dishwasher smell, you’re not alone. Fortunately, there are numerous effective methods to eliminate the offending odor and restore your dishwasher to its pristine state.

Identify the Source of the Smell

Before addressing the problem, it’s crucial to pinpoint the source of the smell. Common culprits include:

  • Food residue: Food particles can accumulate in the dishwasher’s filter, spray arms, and other components, leading to odor.
  • Bacteria and mold: A moist environment inside the dishwasher can foster the growth of bacteria and mold, resulting in an unpleasant smell.
  • Detergent buildup: Excess detergent or rinse aid can leave a residue on dishes and the dishwasher’s interior, creating an odor.
  • Hard water: Minerals in hard water can form scale deposits on the dishwasher’s components, which can trap food particles and bacteria.

How to Get Rid of Dishwasher Smell Using Home Remedies

1. Vinegar Rinse

Vinegar is a natural deodorizer and disinfectant. Pour 2 cups of white vinegar into the dishwasher and run it through a hot cycle without dishes. The vinegar will eliminate odor-causing bacteria and dissolve any buildup.

2. Baking Soda Paste

Baking soda absorbs odors and neutralizes acidity. Create a paste by mixing equal parts baking soda and water. Apply the paste to the dishwasher’s interior, including the filter and spray arms, and let it sit for several hours. Wipe it away with a damp cloth.

3. Lemon Juice

Lemon juice is a natural antibacterial and deodorizer. Cut a lemon in half and squeeze the juice into the dishwasher. Run it through a hot cycle to freshen and deodorize.

4. Bleach Solution

Bleach is a powerful disinfectant, but it should be used sparingly and only as a last resort. Mix 1/2 cup of bleach with 1 gallon of water. Pour the solution into the dishwasher and let it sit for 30 minutes. Run the dishwasher through a hot cycle to rinse away the bleach residue.

How to Get Rid of Dishwasher Smell Using Commercial Products

5. Dishwasher Cleaner Tablets

Commercial dishwasher cleaner tablets are specifically designed to remove odor and buildup. Follow the manufacturer’s instructions for use.

6. Dishwasher Rinse Aid

Rinse aid helps prevent water spots and reduces the buildup of detergent residue. Use a rinse aid specifically formulated for dishwashers.

Preventive Measures

7. Regular Cleaning

Regular cleaning is key to preventing dishwasher odor. Empty the filter regularly and clean the spray arms and interior with a damp cloth.

8. Proper Loading

Load dishes properly to ensure that water and detergent reach all surfaces. Avoid overloading the dishwasher.

9. Use High-Quality Detergent

Use a high-quality dishwasher detergent that is designed to prevent odor and buildup. Avoid using too much detergent.

10. Keep the Dishwasher Door Open

After a cycle, leave the dishwasher door open slightly to allow air to circulate and prevent moisture buildup.

Resolving Specific Dishwasher Odor Issues

11. Sour Smell

A sour smell may indicate the presence of mold or bacteria. Try using vinegar or baking soda paste to eliminate odor and disinfect.

12. Metallic Smell

A metallic smell may be caused by rust or corrosion. Check the dishwasher’s filter and spray arms for signs of rust. Replace any rusted components.

13. Chemical Smell

A chemical smell may be caused by detergent or rinse aid buildup. Use commercial dishwasher cleaner tablets to remove the buildup.
