Why Use Vinegar to Clean Your Dishwasher?
Vinegar, particularly distilled white vinegar, is a powerhouse cleaner due to its acetic acid content, which gives it antibacterial and antifungal properties. According to the experts at Good Housekeeping, vinegar is a natural way to tackle limescale, soap scum, and food residue that can accumulate in your dishwasher over time. Plus, it’s non-toxic, making it a safe choice for households with kids or pets. While it won’t kill all germs (like some chemical disinfectants), it’s highly effective for general sanitizing and deodorizing.
Before we dive into the cleaning process, let’s explore why dishwashers need regular cleaning. Dishwashers are warm, moist environments—perfect breeding grounds for mold, mildew, and bacteria if not properly maintained. Hard water deposits and leftover food particles can also clog the system, reducing its efficiency. Vinegar helps dissolve these deposits and keeps your appliance running smoothly.

Step-by-Step Guide to Disinfecting Your Dishwasher with Vinegar
Here’s a thorough method to disinfect your dishwasher using vinegar, compiled from trusted sources like The Spruce and Bob Vila’s cleaning guides.
What You’ll Need:
- Distilled white vinegar (about 1-2 cups)
- A dishwasher-safe bowl or cup
- A soft cloth or sponge
- Optional: Baking soda (for extra deodorizing)
- Optional: A toothbrush or small scrub brush (for detailed cleaning)
Step 1: Empty the Dishwasher and Inspect
Start by removing all dishes, utensils, and racks from your dishwasher. Check the drain at the bottom for food debris, small bones, or other blockages. According to Bob Vila, “Even tiny scraps can harbor bacteria or cause clogs, so use a paper towel or cloth to clear them out.” If the filter is removable (check your manual), take it out and rinse it under warm water.
Step 2: Clean the Interior Manually
Dip a cloth or sponge in a mixture of warm water and a splash of vinegar. Wipe down the door, gasket, and edges where grime tends to build up. For stubborn spots, The Spruce recommends using an old toothbrush dipped in vinegar to scrub crevices. Pay special attention to the rubber seal around the door—it’s a common spot for mold growth.
Step 3: Run a Vinegar Wash Cycle
Place a dishwasher-safe bowl or cup filled with 1-2 cups of distilled white vinegar on the top rack of the empty dishwasher. “The top rack ensures the vinegar disperses evenly during the cycle,” notes the team at Good Housekeeping [(( Good Housekeeping ))]. Set your dishwasher to its hottest cycle (often labeled “sanitize” or “heavy”) and run it. The heat combined with vinegar will break down limescale and kill off lingering bacteria.
Step 4: Optional Baking Soda Boost
For extra deodorizing power, sprinkle about ½ cup of baking soda across the bottom of the dishwasher after the vinegar cycle. Run a short, hot cycle again. Bob Vila explains, “Baking soda neutralizes odors and helps scrub away any remaining residue” [(( Bob Vila ))]. This step is especially useful if your dishwasher has a lingering smell.
Step 5: Wipe Down and Air Dry
Once the cycle is complete, open the door and let the interior air dry. Use a clean, dry cloth to wipe away any leftover moisture or loosened debris. Reassemble the racks and filter, and you’re done! Your dishwasher should now be fresh, clean, and ready to tackle your next load of dishes.

Enhancing the Cleaning Process: Tips and Tricks
Vinegar is versatile, but there are ways to maximize its effectiveness and keep your dishwasher in top shape long-term. Here are some additional insights:
Tackle Hard Water Stains
If you live in an area with hard water, mineral deposits can dull your dishwasher’s performance. The Kitchn suggests running a vinegar cycle monthly to prevent buildup. For severe limescale, you might consider a commercial descaler once a year, but vinegar is a gentler, regular solution.
Clean the Spray Arms
Over time, the tiny holes in the dishwasher’s spray arms can clog with debris. Remove them (consult your manual) and soak them in a bowl of vinegar for 15-20 minutes. Use a toothpick or small brush to clear the holes, then rinse and reattach.
Avoid Overloading
Prevention is key. HGTV advises against overloading your dishwasher, as it can trap food particles and reduce cleaning efficiency. Scrape plates before loading them to minimize buildup that vinegar will later need to tackle.
Add Essential Oils for a Fresh Scent
For a pleasant aroma, add a few drops of lemon or tea tree essential oil to the vinegar before running the cycle. According to Real Simple, tea tree oil also has natural antimicrobial properties, enhancing the disinfecting process.

How Often Should You Clean Your Dishwasher?
Experts differ slightly on frequency, but a good rule of thumb comes from Whirlpool’s official site: “Clean your dishwasher with vinegar every 1-2 months, or more often if you notice odors or reduced performance.” Heavy users or households with hard water might lean toward monthly cleanings. Between deep cleans, wipe the interior weekly to keep grime at bay.

Safety Notes and Precautions
While vinegar is safe and natural, there are a few things to keep in mind:
- Don’t Mix Vinegar with Bleach: Combining these two can create toxic chlorine gas. Stick to one cleaner at a time.
- Check Manufacturer Guidelines: Some high-end dishwashers have specific cleaning instructions. Refer to your manual to avoid voiding warranties.
- Use Distilled Vinegar: Apple cider or balsamic vinegar can leave residue or stains due to their sugar content.

FAQ: Common Questions About Disinfecting a Dishwasher with Vinegar
1. Can vinegar damage my dishwasher?
No, vinegar is safe for most dishwashers when used as directed. The acetic acid is mild enough not to harm stainless steel, plastic, or rubber components. However, avoid excessive use on delicate finishes—stick to monthly cleanings.
2. Why does my dishwasher still smell after using vinegar?
Lingering odors could indicate trapped food in the filter or drain. Double-check these areas and run a second cycle with baking soda. Persistent smells might require a professional inspection for hidden mold.
3. Is vinegar better than commercial dishwasher cleaners?
It depends on your goal. Vinegar excels at removing limescale and odors naturally, but commercial cleaners may have stronger disinfectants for heavy bacteria. For routine maintenance, vinegar is a cost-effective, eco-friendly choice.
4. Can I use vinegar and baking soda together in one cycle?
Not recommended. Mixing them in the same cycle causes a fizzing reaction that neutralizes their cleaning power. Use them in separate cycles, as outlined above, for the best results.
5. How do I know if my dishwasher needs cleaning?
Signs include cloudy dishes, bad smells, visible grime, or white chalky deposits (limescale). If your dishes aren’t as clean as they used to be, it’s time for a vinegar refresh.
