DIY Dishwasher Cleaner Recipe

Can You Clean a Dishwasher With Natural Ingredients?

Yes — white vinegar, baking soda, and citric acid are all effective at removing odors, mineral deposits, and light grease buildup from inside a dishwasher. These natural cleaning methods are inexpensive, widely available, and free of harsh chemicals. Here are the best DIY dishwasher cleaner recipes and how to use them.

Recipe 1: White Vinegar Clean (Best for Mineral Deposits and Odors)

White vinegar is mildly acidic and dissolves mineral deposits, cuts through light grease, and neutralizes odors effectively.

What You Need

• 1 cup (240ml) of white vinegar
• A dishwasher-safe cup or bowl

How to Do It

1. Make sure the dishwasher is empty — remove all dishes
2. Pour one cup of white vinegar into a dishwasher-safe cup or bowl
3. Place the cup upright on the top rack of the dishwasher
4. Run the hottest, longest cycle available — do not use detergent
5. When the cycle finishes, leave the door open for 15 to 20 minutes to air out

How often: Once a month for maintenance, or whenever you notice odors or mineral buildup.

Recipe 2: Baking Soda Deodorize (Best for Odors and Stains)

Baking soda is a mild abrasive and natural deodorizer that removes odors and light staining from the dishwasher interior.

What You Need

• 1 cup (200g) of baking soda

How to Do It

1. After running the vinegar cycle (or on its own), sprinkle one cup of baking soda across the floor of the empty dishwasher tub
2. Run a short hot cycle — do not use detergent
3. The baking soda will dissolve and deodorize the interior

How often: Monthly, ideally after the vinegar cycle for a two-step clean.

Recipe 3: Vinegar + Baking Soda Two-Step Clean (Most Effective DIY Method)

Combining both methods in sequence gives the most thorough DIY clean.

Step 1

1. Place a cup of white vinegar on the top rack of an empty dishwasher
2. Run a full hot cycle

Step 2

1. Sprinkle one cup of baking soda on the floor of the tub
2. Run a short hot cycle

Note: Do not mix vinegar and baking soda in the same cycle — they neutralize each other and reduce effectiveness. Always run them as separate cycles.

Recipe 4: Citric Acid Clean (Best for Heavy Limescale)

Citric acid is more effective than vinegar at dissolving heavy limescale and mineral buildup. It is the active ingredient in many commercial dishwasher cleaners.

What You Need

• 2 tablespoons of citric acid powder (available in grocery stores or online)

How to Do It

1. Place the citric acid powder in the detergent dispenser compartment
2. Run an empty dishwasher on the hottest cycle available
3. The citric acid will dissolve limescale from the interior, spray arms, and pump

How often: Every one to two months in hard water areas.

DIY vs Commercial Dishwasher Cleaner Tablets

DIY methods are effective for light maintenance and odor control, but they have limitations:

• They do not penetrate as deeply into the pump and hoses as commercial cleaners
• They are less effective on heavy grease buildup
• Vinegar used regularly in the dispenser can degrade rubber seals over time

For a thorough monthly clean that reaches inside the pump and hoses, Affresh Dishwasher Cleaner Tablets are specifically engineered to remove grease, limescale, and odor-causing bacteria from areas DIY methods cannot reach.

Final Tips

• Always run DIY cleaning cycles on an empty dishwasher
• Never mix vinegar and baking soda in the same cycle — run them separately
• Citric acid is the most effective natural option for heavy limescale
• Combine DIY methods with manual filter cleaning every two to four weeks for best results
