A dishwasher is one of the most convenient appliances in any kitchen, but over time, it can accumulate grease, limescale, and food debris. If your dishes aren’t coming out as clean as they used to or you notice a musty odor, it might be time for a deep clean. While there are many commercial cleaners available, citric acid is a natural, affordable, and highly effective alternative.
In this article, we’ll explore:
✔ Why citric acid works so well for cleaning dishwashers
✔ Step-by-step instructions for a thorough clean
✔ Additional maintenance tips to keep your dishwasher fresh
Why Use Citric Acid to Clean a Dishwasher?
Citric acid is a natural cleaning agent found in citrus fruits like lemons and limes. It’s a powerful:
✅ Descaling agent – Breaks down limescale and mineral deposits from hard water.
✅ Deodorizer – Neutralizes unpleasant odors caused by trapped food particles.
✅ Antibacterial cleaner – Helps eliminate mold and bacteria buildup.
Unlike harsh chemicals, citric acid is eco-friendly, non-toxic, and safe for septic systems. Plus, it’s inexpensive and easy to find in powder form at grocery stores or online.
How to Clean a Dishwasher With Citric Acid
What You’ll Need:
- 1 cup of citric acid powder (or substitute with 2 cups of white vinegar)
- A dishwasher-safe bowl
- A soft brush or sponge
- A microfiber cloth
Step 1: Empty the Dishwasher
Remove all dishes, racks, and utensil holders. Check the filter (usually at the bottom) and remove any large debris.
Step 2: Clean the Filter and Spray Arms
- Soak the filter in warm water with a teaspoon of citric acid to loosen grime.
- Use a soft brush to scrub the spray arms to ensure no clogs are blocking water flow.
Step 3: Run a Hot Wash Cycle With Citric Acid
- Place a dishwasher-safe bowl filled with 1 cup of citric acid powder on the top rack.
- Run the dishwasher on the hottest cycle (without any dishes). The heat helps dissolve buildup more effectively.
Step 4: Wipe Down Interior Surfaces
After the cycle, wipe the door seals, edges, and interior with a damp microfiber cloth to remove any remaining residue.
Step 5: Optional Freshening Boost
For extra freshness, sprinkle a little baking soda at the bottom of the dishwasher and run a short rinse cycle.
Additional Dishwasher Maintenance Tips
To keep your dishwasher running smoothly between deep cleans:
🔹 Rinse dishes before loading – Prevents food particles from clogging the filter.
🔹 Leave the door slightly open after cycles – Reduces moisture and prevents mold growth.
🔹 Clean monthly – Regular citric acid treatments prevent heavy buildup.
🔹 Check for hard water issues – If you have hard water, use a rinse aid to minimize limescale.
Final Thoughts
Cleaning your dishwasher with citric acid is a simple, natural, and cost-effective way to maintain its performance and extend its lifespan. By following these steps once a month, you’ll ensure sparkling clean dishes and a fresh-smelling appliance every time.
