A washing machine is supposed to clean your clothes, but sometimes it starts to smell worse than the laundry itself. If you’ve noticed a musty or sour odor coming from your washer, you’re not alone. This is a common problem caused by detergent buildup, trapped moisture, and bacteria growing inside the machine.
The good news is that you can remove the bad smell from your washing machine using simple cleaning methods and ingredients you probably already have at home.
Why Washing Machines Start to Smell
Washing machines are constantly exposed to moisture, soap, and dirt from clothing. Over time, these elements can build up inside the drum, rubber seals, and detergent compartments.
Common causes of washing machine odor include:
- Detergent and fabric softener residue
- Mold and mildew growth
- Trapped water inside the drum or gasket
- Washing at low temperatures frequently
- Leaving wet clothes inside the machine too long
Once these odors develop, they can transfer to your clothes, making laundry smell unpleasant.
What You’ll Need
Before starting the cleaning process, gather the following supplies:
- White vinegar
- Baking soda
- Microfiber cloth or sponge
- Old toothbrush or small cleaning brush
- Warm water
- Dish soap (optional)
These ingredients help break down residue, kill odor-causing bacteria, and refresh the machine.
Step-by-Step: How to Remove Bad Smell from Washing Machine
Follow these steps to deep-clean your washing machine and eliminate odors.
- Empty the washing machine
Make sure the drum is completely empty before cleaning. - Add vinegar to the drum
Pour two cups of white vinegar directly into the drum. Vinegar helps dissolve detergent buildup and kill odor-causing bacteria. - Run a hot wash cycle
Set the machine to the hottest and longest cycle available. This helps flush out residue and sanitize the interior. - Add baking soda
After the vinegar cycle finishes, sprinkle half a cup of baking soda into the drum and run another hot cycle. Baking soda neutralizes odors. - Clean the rubber seal and door
Use a cloth or toothbrush with warm soapy water to clean the rubber gasket around the door, where mold and mildew often grow. - Clean the detergent drawer
Remove the detergent drawer and wash it with warm water and dish soap. Scrub away any buildup. - Wipe the interior
After the cycle finishes, wipe the inside of the drum and door with a clean cloth. - Leave the door open
Allow the washer to air dry completely to prevent moisture buildup.
How to Remove Mold Smell from Washing Machine
If the odor is caused by mold or mildew, you may need to give extra attention to hidden areas.
Focus on:
- The rubber door gasket
- The detergent dispenser
- The drain filter
- The inside edges of the drum
A vinegar and water solution works well to remove mold buildup in these areas.

Once your washing machine is clean, these habits will help keep it smelling fresh.
- Leave the door open after every wash cycle.
- Wipe the rubber seal regularly.
- Use the correct amount of detergent.
- Run a hot cleaning cycle once a month.
- Remove clothes promptly after washing.
These simple steps prevent moisture and detergent buildup from causing odors.
