How to Deep Clean Your Dishwasher Filter and Interior

Does your dishwasher leave spots on glasses or smell musty? Food debris and grease buildup in the filter and interior can reduce performance, cause odors, and even damage your appliance over time. The right deep cleaning routine can restore your dishwasher’s efficiency and extend its lifespan. In this guide, we’ll cover step-by-step methods to clean the filter, interior, and hidden crevices.

Key Takeaways

• Remove and scrub the filter weekly to prevent clogs.
• Use vinegar and baking soda for a natural deep clean.
• Inspect spray arms and door seals for hidden grime.
• Run a monthly maintenance cycle to prevent buildup.

1. Remove and Clean the Dishwasher Filter

Locate the filter at the bottom of your dishwasher—typically a cylindrical or mesh component. Twist or lift it out, then:

• Soak in warm, soapy water for 10 minutes.
• Scrub with a soft brush to dislodge grease and food particles.
• Rinse thoroughly before reinstalling.

For stubborn residue, soak in a 1:1 vinegar-water solution. Check your manual for model-specific instructions, as some filters are self-cleaning.

2. Wipe Down the Interior

Use a microfiber cloth dipped in vinegar to clean:

• Spray arms: Clear clogged holes with a toothpick.
• Door seals: Remove mold or mildew with a baking soda paste.
• Racks: Scrub with dish soap and warm water.

For stainless steel interiors, avoid abrasive scrubbers to prevent scratches. For tough grease, use a degreasing solution.

3. Run a Vinegar and Baking Soda Cycle

Natural cleaners break down buildup without harsh chemicals:

1. Place a cup of white vinegar on the top rack.
2. Run a hot water cycle to disinfect and deodorize.
3. Sprinkle baking soda on the bottom and run a short cycle to neutralize odors.

Repeat monthly for maintenance. For hard water stains, add citric acid to the detergent compartment.

4. Clean Hidden Areas

Check these often-missed spots:

• Drain area: Remove debris with a paper towel.
• Detergent dispenser: Wipe with a damp cloth.
• Exterior: Use a mild cleaner for the control panel and handle.
