How to Eliminate Dishwasher Odor: Fresh Scent Tips & Tricks
To eliminate dishwasher odor, clean the filter, run a hot wash with vinegar, and sprinkle baking soda on the bottom overnight before a final rinse cycle. Ensure regular cleaning of seals and remove leftover food promptly.
Identify and Remove the Source of the Odor

Inspect for Food Particles and Residue
One of the primary culprits behind a smelly dishwasher is leftover food particles. These tiny scraps can get trapped in various nooks and crannies within your dishwasher, leading to unpleasant odors.
To combat this, it is essential to inspect your dishwasher for leftover food after each cycle.
Pay special attention to the base of the machine, the corners, and around the door seals, where residue commonly accumulates. Removing these particles promptly ensures they do not decompose and start to smell.
Clean the Filter and Trap Regularly
The filter and trap in your dishwasher play a significant role in preventing food waste from re-entering the washing area.
Over time, these can become clogged, which not only reduces the efficiency of your dishwasher but also leads to odor build-up.
To prevent this, make cleaning your dishwasher’s filter and trap a regular part of your kitchen cleaning routine. Most filters can be easily removed and cleaned with warm, soapy water.
Check and Clean the Spray Arms
The spray arms are vital for distributing water evenly throughout the dishwasher during a cycle. However, they have small holes that can become clogged with food particles or mineral deposits from hard water.
Check these arms periodically to ensure they are clear and clean. A toothpick or small brush can be effective tools for dislodging any blockages.
Look for Mold or Mildew Growth
Damp environments are breeding grounds for mold and mildew. If you notice a musty smell coming from your dishwasher, inspect it for visible signs of mold or mildew, particularly around the rubber seals of the door.
These should be cleaned immediately to prevent the spread of spores and eliminate the source of the odor.
Ensure Proper Drainage
Standing water is another common cause of dishwasher odors. This can occur if the dishwasher is not draining properly, often due to a clog in the drain hose.
Ensuring that your dishwasher drains correctly after each cycle will help to prevent the growth of bacteria and the odors they produce.
Clean and Deodorize the Dishwasher

Natural Cleaning with Vinegar and Baking Soda
Vinegar and baking soda are two natural and effective cleaning agents that can help remove odors from your dishwasher.
To utilize their cleaning power, start by running an empty hot water cycle with a cup of white vinegar placed on the top rack.
After the cycle, sprinkle baking soda around the bottom of the dishwasher and leave it overnight. In the morning, run another cycle to rinse everything away.
This process will not only deodorize your dishwasher but also clean and freshen the interior.
Hot Water Cycle with Dishwasher Cleaner
For a thorough clean, you can also use a commercial dishwasher cleaner. These products are designed to break down residue that may lead to odors.
Follow the manufacturer’s instructions, typically involving running a hot water cycle with the cleaner inside. These cleaners are especially useful for reaching areas that are difficult to clean manually.
Odor Absorption Techniques
Activated charcoal and coffee grounds are natural odor absorbers that can help maintain a fresh-smelling dishwasher between deep cleans.
Place a bowl of activated charcoal or coffee grounds in the dishwasher when not in use to absorb residual odors. This is an easy and natural method to keep your dishwasher smelling fresh.
Use Bleach Cautiously for Mold
When dealing with mold, bleach can be a powerful ally. However, it should be used with caution, especially if your dishwasher has a stainless steel interior.
For dishwashers with plastic interiors, a bleach solution can be used to remove mold spots. Remember to ventilate the area well and run a thorough rinse cycle after cleaning with bleach to remove any residue.
Prevent Future Odors

Rinse Dishes Before Loading
Rinsing dishes before placing them in the dishwasher can significantly reduce the likelihood of food particles being left behind.
This simple step can go a long way in preventing the build-up of food residue that can lead to odors.
It’s not necessary to wash dishes completely, but a quick rinse to remove the bulk of the food will help keep your dishwasher clean and odor-free.
Air Out the Dishwasher After Cycles
Moisture can linger after a wash cycle, creating an environment for odors to develop. To combat this, leave your dishwasher door slightly open after each use.
This allows air to circulate and helps to dry out the interior, preventing the growth of bacteria and mold that can cause smells.
Utilize Rinse Aids for Better Drying
Rinse aids are not just for spotless glasses. They also help water to sheet off dishes and the interior of the dishwasher, which speeds up the drying process.
Faster drying means less time for mold and bacteria to grow. Adding a rinse aid to your dishwasher can be an effective way to reduce the chances of developing odors.
Regular Maintenance and Cleaning Routines
Establishing a regular maintenance and cleaning schedule for your dishwasher is crucial to prevent odors from taking hold.
This includes wiping down the seals, cleaning the filter and trap, and using a dishwasher cleaner or natural deodorizer like vinegar on a monthly basis.
By staying ahead of potential problems, you can keep your dishwasher smelling fresh all year round.
Adjust Dishwasher Settings
Finally, make sure you are using the correct settings on your dishwasher. Some dishwashers have specific settings for increased temperature or extra drying, which can help prevent the conditions that lead to odor development.
Consult your dishwasher’s manual to understand the best settings for optimal performance and drying.
Maintaining a fresh-smelling dishwasher is not just about cleanliness; it also enhances the performance of your appliance and extends its lifespan.
By following the steps outlined above, you can tackle dishwasher odors head-on and enjoy a cleaner, fresher kitchen environment.
