A dishwasher is a lifesaver in the kitchen—but it can get dirty, smelly, and clogged over time. Even if your dishes look clean, grease, limescale, and food residue can build up inside.
The best part? You don’t need harsh chemicals. Using vinegar and baking soda is a natural, safe, and effective way to clean your dishwasher, remove odors, and maintain optimal performance. This beginner-friendly guide walks you through the process step by step.
Why Vinegar and Baking Soda Work So Well
Vinegar and baking soda are a dynamic duo for cleaning:
- Vinegar is acidic, dissolving mineral deposits, grease, and soap scum.
- Baking soda is mildly abrasive, deodorizing and scrubbing away stuck-on residue without scratching surfaces.
Together, they remove buildup, neutralize odors, and leave your dishwasher sparkling—all without harsh chemicals or scrubbing.
Stop doing this: relying on your dishwasher’s regular detergent alone. Over time, buildup can affect cleaning performance, leave residue on dishes, and cause odors.
What You’ll Need
Gather everything you’ll need before starting:
- White distilled vinegar
- Baking soda
- Measuring cup
- Dishwasher-safe bowl or cup
- Soft cloth or sponge
- Toothbrush (optional, for corners and seals)
- Rubber gloves (optional)
Step by Step: How to Clean Your Dishwasher with Vinegar and Baking Soda
Follow these steps for the best results:
- Empty the dishwasher completely: Remove all dishes, utensils, and racks if possible.
- Check and clean the filter: Remove any food debris from the bottom of the dishwasher to prevent clogs and ensure thorough cleaning.
- Place a cup of vinegar: Fill a dishwasher-safe bowl or cup with 1–2 cups of white distilled vinegar and place it on the top rack.
- Run a hot water cycle: Start a full cycle using the hottest setting. This allows vinegar to circulate and dissolve mineral buildup and grease.
- Sprinkle baking soda: Once the vinegar cycle is complete, sprinkle 1 cup of baking soda evenly across the bottom of the dishwasher.
- Run a short hot water cycle: This cycle helps lift stains, neutralize odors, and polish the interior.
- Wipe seals and edges: Use a soft cloth or toothbrush dipped in vinegar to clean door seals, corners, and other hard-to-reach areas.
- Rinse and dry: Leave the dishwasher door open to air dry, ensuring no moisture is trapped that could cause odors or mold.
How Much Vinegar and Baking Soda to Use
- Vinegar: 1–2 cups in a dishwasher-safe cup
- Baking soda: 1 cup sprinkled directly on the bottom of the dishwasher
This combination works for standard 12- to 14-place dishwashers. For heavily soiled machines, repeat the process monthly.
How Often Should You Clean Your Dishwasher?
- Heavy usage or hard water areas: Monthly
- Average households: Every 2–3 months
- If dishes start smelling or spotting, clean immediately
Regular cleaning improves performance, prevents odors, and extends the life of your appliance.
