How to Clean a Dishwasher with Baking Soda and Vinegar: Step-by-Step Instructions
Step 1: Empty the Dishwasher

- Remove all dishes, utensils, and racks. You want a clear space to let vinegar and baking soda work their magic.
- Pro Tip: Take out the filter and soak it in warm soapy water for 10 minutes.
Step 2: Run a Vinegar Cycle

- Place a dishwasher-safe bowl filled with white vinegar on the top rack. Run a hot water cycle. This breaks down grease and eliminates odors.
Step 3: Sprinkle Baking Soda

- After the vinegar cycle finishes, sprinkle one cup of baking soda evenly across the bottom of the dishwasher. Run a short, hot cycle. This freshens and brightens the interior.
Step 4: Scrub Crevices

- Use a toothbrush or small brush to scrub around the door gasket, spray arms, and corners. These spots often hide food particles.
Step 5: Wipe & Dry

- Finish by wiping the inside walls and edges with a microfiber cloth. Your dishwasher should now smell clean and look refreshed.
Pro Tips & Common Mistakes to Avoid
- Don’t mix vinegar and baking soda in one cycle — they cancel each other out.
- Avoid bleach if your dishwasher has stainless steel parts.
- Clean the filter monthly for best performance.
- Run this baking soda and vinegar method every 4–6 weeks.
- If dishes still look cloudy, check your rinse aid setting.
- Don’t forget the spray arms unclog holes with a toothpick.
- Regular maintenance can extend your machine’s life by years.
Variations or Alternative Methods
- Deep Clean with Lemon Juice: Swap vinegar with lemon juice for a natural citrus boost.
- Commercial Dishwasher Cleaner: If buildup is heavy, use a store-bought cleaner once every few months.
- Professional Service: For mold or drainage issues, a technician may be the best solution.
Safety & Maintenance Notes
- Always unplug or turn off the dishwasher before deep scrubbing.
- Never use harsh chemicals like bleach and ammonia together.
- Wipe spills immediately to prevent corrosion.
- Keep the door slightly open after cycles to prevent mold growth.
