How to Clean a Dishwasher With Baking Soda and Vinegar: The Step-by-Step Guide

Deep cleaning your appliance every month or two using basic white vinegar and baking soda is essential to ensure it washes and deodorizes your kitchenware properly. Over time, trapped food particles, grease, and hard water residue accumulate inside the filter, spray zones, and door seals, degrading washing performance and leaving persistent odors.

Restoring peak efficiency does not require commercial specialty cleansers. By targeting individual components with a thick baking soda paste and running two distinct, sequential hot water cycles, you can eliminate stubborn buildup and deodorize the entire machine.

Essential Preparation Before You Start Cleaning

Before applying any cleaning solutions, you must prepare the appliance properly. Ensure the unit is completely empty, with every dish, cup, and utensil removed from the interior.

Inspect the bottom basin, the perimeter of the door, the utensil basket, and the area directly surrounding the drain. Manually remove any large visible debris, food scraps, or foreign items that have settled at the bottom.

A common mistake in practice is running cleaning agents while dishes are still inside, which prevents the solutions from reaching critical internal housing components and traps circulating debris.

Component Breakdown: Cleaning the Door, Filter, and Racks

The interior mechanisms require manual attention before running wash cycles. Lingering grime often hides in gaskets, drainage screens, and wire joints where wash water cannot easily dislodge it.

Scrubbing the Door and Crevices

The door edges and surrounding gasket do not receive direct pressurized water during regular wash runs, making them prime spots for grime accumulation.

1. Fully lower the dishwasher door until it sits parallel to the floor.
2. Wipe down the entire door interior and side edges using a damp microfiber cloth.
3. Mix equal parts baking soda and warm water in a small bowl until it forms a thick, spreadable paste.
4. Dip a non-abrasive brush into the mixture and thoroughly scrub the door surface, paying close attention to nooks, edges, and corners.
5. Wipe away the remaining residue with a clean, damp microfiber cloth.

Deep-Cleaning the Filter

Dishwasher filters vary across different appliance models; some are fully removable while others remain fixed in place. Always verify your specific model’s manual before disassembly. If your model features a removable filter, follow these restorative steps:

• Remove the filter unit according to the manufacturer’s directions.
• Rinse the assembly inside and out under running water, using a brush to clear loose particles.
• Apply a paste of equal parts baking soda and warm water to scrub away stubborn, stuck-on grease.
• Submerge the filter in a bowl filled with equal parts warm water and white vinegar for up to 30 minutes.
• Rinse completely with clean warm water and let it air-dry on a drying rack or lint-free towel before reinstalling.

Racks and Utensil Holders

Slide out both the top and bottom racks. If heavy buildup is present, soak them in a bathtub or deep sink filled with warm water and mild dish soap for up to 30 minutes. For remaining debris, apply the equal-parts baking soda paste, scrub with a small brush, let sit for 15 minutes, rinse clean, and air-dry.

For the utensil basket, shake it upside down over the trash to dislodge trapped cutlery debris. Submerge the basket in equal parts warm water and vinegar for up to 30 minutes. Scrub remaining spots with the baking soda paste, let it sit for 15 minutes, rinse thoroughly, and let dry.

The Two-Step Hot Water Cycle Method

Once every removable part and perimeter surface is spotless, clean the internal plumbing and spray arms using a two-phase sanitizing run.

Many homeowners assume mixing vinegar and baking soda together in a single cycle creates a superior clean. In reality, combining acid and base simultaneously neutralizes both agents, canceling out their individual cleaning powers. Running them sequentially delivers maximum grease breakdown followed by complete deodorization.

1. Place a dishwasher-safe bowl containing one to two cups of white vinegar upright on the top rack. Do not add detergent, pods, or dishes.
2. Run a full cycle using the hottest water setting available.
3. Remove the bowl after the cycle completes, then sprinkle approximately one cup of baking soda across the bottom basin.
4. Execute a second hot water cycle without detergent.
5. Open the door and wipe away any lingering baking soda residue with a damp microfiber cloth.

💡 Maintaining this routine every month or two preserves component longevity and prevents foul odor transfer to everyday glassware.

🔍 Checking your drainage filter regularly ensures food waste does not recirculate during heavy wash loads.
