Dishwashers can accumulate residue, odors, and buildup over time, affecting their performance. Cleaning with vinegar and baking soda is an effective, natural way to remove grime and restore freshness.

To clean a dishwasher, pour a cup of vinegar into the bottom and run a hot water cycle, then sprinkle baking soda on the base and run a short, hot cycle to deodorize and remove stains. This method uses common household ingredients to maintain the appliance without harsh chemicals.
People seeking a simple, safe solution will find this approach practical and easy to follow. It helps keep the dishwasher running efficiently while preventing unpleasant smells.
Benefits of Cleaning a Dishwasher with Vinegar and Baking Soda

Using vinegar and baking soda to clean a dishwasher helps remove buildup, eliminate odors, and maintain the appliance’s efficiency. This method targets mineral deposits, soap scum, and trapped food particles, which can reduce performance and cause unpleasant smells.
Improving Dishwasher Performance
Vinegar’s acidity breaks down minerals and soap scum that accumulate on the dishwasher’s heating element and interior surfaces. This removal allows water to heat properly and water jets to spray more effectively.
Baking soda acts as a mild abrasive that loosens stuck-on food debris and grease. Combined, they prevent clogs in drainage and spray arms, ensuring dishes come out cleaner and cycles run smoothly.
Regular cleaning with these ingredients can extend the lifespan of the dishwasher by avoiding blockages and mechanical strain caused by residue buildup.
Removal of Odors
Dishwashers often develop sour or musty smells from trapped food particles and mold growth in moist areas. Vinegar’s natural deodorizing properties neutralize these odors rather than just masking them.
Baking soda absorbs odors by balancing pH levels within the dishwasher’s interior. Using them together removes stale smells from rubber seals, filters, and corners where water stagnation occurs.
Consistent cleaning keeps the dishwasher smelling fresh, making it more pleasant to use and preventing odors from transferring to dishes or utensils.
Prevention of Limescale and Residues
Hard water leads to limescale buildup, which reduces dishwasher efficiency and may cause damage over time. Vinegar dissolves calcium and magnesium deposits that cause these white, crusty residues.
Baking soda helps scrub away remaining particles without damaging surfaces. This combination protects the appliance’s metal and plastic parts from corrosion.
Regular use of vinegar and baking soda prevents residue buildup that can decrease water flow and heating efficiency, promoting better dishwashing results.
What You Need for Cleaning

The process requires specific items to ensure effective cleaning. Understanding the types and qualities of these materials makes the task easier and improves results.
Supplies and Tools Checklist
The primary supplies include white vinegar, baking soda, and access to hot water. White vinegar is used for its acidity, which helps dissolve mineral deposits and grease. Baking soda acts as a mild abrasive and deodorizer.
Tools needed are measuring cups, a soft cloth or sponge, and a toothbrush for scrubbing small areas. Using a non-abrasive sponge is important to avoid scratching the dishwasher interior. A measuring cup ensures accurate amounts of vinegar and baking soda.
Choosing the Right Vinegar
White distilled vinegar is the best choice. It is clear, affordable, and has consistent acidity, typically around 5%. Avoid flavored or colored vinegars, which can stain or leave residues.
The vinegar must be pure and unsweetened to avoid sticky buildup. Distilled white vinegar cleans without damaging dishwasher parts or seals. It is important not to substitute with other vinegar varieties like apple cider vinegar, which may have different acidity levels and additional residues.
Selecting Baking Soda
Use standard, pure baking soda intended for cooking or cleaning. Avoid baking powders or baking soda mixed with additives. Pure sodium bicarbonate is effective as a gentle scrubbing agent.
Baking soda deodorizes without harsh chemicals and helps remove stains and buildup. It is inexpensive and readily available. Using the correct baking soda ensures safe interaction with vinegar and avoids mineral deposits or residue inside the dishwasher.
How to Prepare the Dishwasher

Preparing the dishwasher properly ensures the cleaning process with vinegar and baking soda is effective. It involves clearing the dishwasher completely and addressing any removable parts that can collect debris and affect performance.
Emptying and Inspecting the Dishwasher
First, the dishwasher must be completely empty. All dishes, utensils, and racks should be removed to allow full access to the interior surfaces.
Next, the user should check the drain area at the bottom for any food particles or debris. Removing blockages will prevent clogs during the cleaning cycle.
The dishwasher door seal should also be inspected for any mold or residue. Wiping it down with a damp cloth will help ensure a tight seal during cleaning.
Cleaning the Removable Parts
Removable components like the filter, spray arm, and utensil holder need to be taken out carefully. These parts often trap grime and mineral buildup.
The filter can be rinsed under hot water and scrubbed with a soft brush to remove leftover particles. Avoid using harsh chemicals that could damage it.
Spray arms can be cleaned by flushing out the holes with a thin object or soaking them in warm, soapy water. The utensil holder can also be washed separately to remove residue.
Step-by-Step Dishwasher Cleaning Process

The cleaning method involves two main cycles: one with vinegar and one with baking soda. Each cycle targets different residues and buildup. For tougher spots, additional treatments may be necessary to fully restore cleanliness.
Using Vinegar for the First Cleaning Cycle
Start by emptying the dishwasher completely. Place a cup of white vinegar in a dishwasher-safe container on the top rack.
Run the dishwasher on the hottest and longest cycle available. The vinegar helps dissolve grease, grime, and mineral deposits inside the appliance. It also deodorizes and removes light buildup.
After the cycle finishes, inspect the interior for any remaining residue. Wipe down the door edges, seals, and racks with a damp cloth to remove loosened debris.
Applying Baking Soda for the Second Cycle
Sprinkle about one cup of baking soda evenly across the bottom of the dishwasher. Avoid placing it in the detergent dispenser.
Run a short, hot water cycle (around 1 hour or less). The baking soda helps eliminate odors and further removes stains and buildup. It also brightens the dishwasher interior.
Once complete, leave the door open for a while to allow the interior to dry and air out. This step helps prevent mold and mildew formation.
Dealing with Stubborn Stains
For tough stains or hard water deposits, mix baking soda with a small amount of water to create a paste. Apply this paste to the stained areas with a sponge or soft brush.
Let it sit for 10-15 minutes before scrubbing gently. Rinse with a damp cloth to remove residue.
If needed, repeat the vinegar cycle after this spot treatment to ensure thorough cleaning. Use a toothbrush to reach grooves and tight spaces.
Safety Tips and Precautions

Using vinegar and baking soda to clean a dishwasher requires care to avoid hazards. Attention to chemical interactions and airflow can prevent damage and ensure safe cleaning.
Avoiding Chemical Reactions
Vinegar is acidic, and baking soda is alkaline; combining them produces carbon dioxide gas and neutralizes the substances. This reaction is safe in measured amounts but should not be mixed in large quantities or sealed containers, as pressure buildup can cause bursting.
Never mix vinegar or baking soda with commercial cleaning products containing bleach or ammonia. Toxic gases may form, posing health risks.
It is best to add vinegar during the rinse cycle and baking soda as a separate step to avoid unwanted reactions. Using only food-grade vinegar and pure baking soda ensures no harmful additives enter the dishwasher.
Proper Ventilation
Cleaning with vinegar produces a strong acetic acid odor, which can irritate the eyes and respiratory system. Baking soda has a mild odor but may still cause discomfort in poorly ventilated areas.
Ensure the kitchen has adequate airflow during and after cleaning. Open windows or activate exhaust fans to disperse fumes quickly.
If someone in the home has respiratory issues, extra ventilation and limited exposure during cleaning are essential. Avoid standing close to the dishwasher while vinegar is in use.
Good ventilation reduces the risk of inhaling vapors and contributes to a safer cleaning environment.
How Often to Clean Your Dishwasher

Dishwashers should be cleaned regularly to maintain optimal performance. Most experts recommend cleaning once a month as a general rule.
If the dishwasher is used daily or handles heavily soiled dishes, cleaning every two to three weeks may be necessary. Residue from food particles, grease, and soap scum can build up faster in these cases.
Conversely, if it is used infrequently, cleaning every six weeks to two months might be sufficient. This helps prevent mold, odors, and mineral buildup.
Signs it needs cleaning sooner:
- Foul or musty smells
- Dishes not coming out fully clean
- Visible residue inside the machine
Creating a cleaning schedule based on usage and water quality will extend the dishwasher’s life. Hard water areas may require more frequent vinegar and baking soda cleaning to reduce mineral deposits.
Alternative Natural Cleaning Methods

Lemon juice is a popular natural cleaner. Its acidic properties help break down grease and remove odors inside the dishwasher. Simply place a cup of lemon juice on the top rack and run a hot cycle.
White distilled vinegar can be used alone as well. Pour one cup into a dishwasher-safe bowl on the top rack and run a hot water cycle to help dissolve grime and eliminate bad smells.
Salt is effective at softening water and preventing mineral build-up. Adding a cup of coarse salt to the bottom of the dishwasher before running a cleaning cycle can improve results.
Essential oils like tea tree or eucalyptus provide antimicrobial benefits and a fresh scent. Adding a few drops to the vinegar or baking soda can increase cleaning power naturally.
Here is a comparison of the methods:
| Method | Use | Benefits |
