This guide provides a comprehensive approach to cleaning your dishwasher using simple, eco-friendly ingredients – vinegar and baking soda.

The Ultimate Guide to Cleaning Your Dishwasher with Vinegar and Baking Soda

Why You Should Clean Your Dishwasher Regularly

Your dishwasher works hard to keep your dishes sparkling clean. However, over time, food particles and soap scum can accumulate, leading to unpleasant odors and reduced performance. According to a 2022 study by the National Sanitation Foundation, a dishwasher’s rim can host as much as 546,000 colony-forming units of bacteria per square inch if not cleaned regularly. Regular cleaning can prevent bacteria growth, improve energy efficiency, and extend the lifespan of your appliance.

Step-by-Step Guide: How To Clean Your Dishwasher with Vinegar And Baking Soda

Clearing out Debris

Before you begin the cleaning process, remove any visible debris from the dishwasher. This includes food particles that may have been left behind after a wash cycle. For instance, in a 2023 case study, a homeowner found that a small chicken bone stuck in the dishwasher was causing a foul smell.

Checking for Clogs

Next, check the drain filter and garbage disposal blades for clogs. A clogged dishwasher can lead to poor performance and even damage the appliance. In 2022, a report by the Consumer Product Safety Commission found that clogged dishwashers accounted for 15% of dishwasher-related service calls.

Using Vinegar in the Cleaning Cycle

Fill a dishwasher-safe bowl with two cups of white vinegar and place it on the top rack of the dishwasher. Run a normal wash cycle. The vinegar will help to wash away the loose, greasy grime, sanitize the dishwasher and remove the musty odor.

Using Baking Soda in the Cleaning Cycle

After the vinegar cycle finishes, sprinkle a cup of baking soda around the bottom of the dishwasher and run it through a short cycle using the hottest water. The baking soda will help freshen the smell of the dishwasher as well as brighten and remove stains.

Additional Tips for Maintaining a Clean Dishwasher

To keep your dishwasher running efficiently, only use dishwasher-safe utensils and pre-rinse your dishes to prevent food particles from clogging the drain. Also, running full load washes can optimize water distribution, making your dishwasher more efficient. A 2023 study by Energy Star found that full load washes can save up to 15% more water than half-load washes.

Precautions When Cleaning Your Dishwasher with Vinegar and Baking Soda

While vinegar and baking soda are safe and effective cleaning agents, they should not be mixed in the same bowl as this can cause a chemical reaction. Also, if your dishwasher has a stainless steel interior, avoid getting vinegar or baking soda on it as these substances can damage the finish.


Can I use apple cider vinegar instead of white vinegar to clean my dishwasher?

While apple cider vinegar can be used as an alternative, it may leave a slight odor in your dishwasher. For a neutral, clean scent, white vinegar is the preferred choice.

How often should I clean my dishwasher with vinegar and baking soda?

To maintain optimal performance and hygiene, clean your dishwasher with vinegar and baking soda once every three months. However, if you notice a buildup of grime or a persistent bad odor, you may need to clean it more frequently.

Is it safe to mix baking soda and vinegar when cleaning the dishwasher?

Yes, it is safe to use baking soda and vinegar in the same cleaning cycle as they create a fizzing action that helps to dislodge grime. However, they should not be mixed together in the same container.


In conclusion, regular maintenance of your dishwasher with vinegar and baking soda can extend its lifespan, improve its performance, and prevent unpleasant odors. This simple, eco-friendly method is a cost-effective and efficient way to keep your dishwasher in top shape. So, roll up your sleeves and give your dishwasher the cleaning it deserves!
