How to Get Rid of Odors in Washing Machines
Learn proven methods to remove musty smells from washing machines, including drum cleaning, gasket deodorizing, and ongoing maintenance for lasting freshness.
To get rid of odors in a washing machine, follow a simple three-step routine: wipe the drum and gasket to remove grime, run a hot empty cycle with a safe deodorizer, and finish with a rinse and air-dry routine. Regular maintenance and using the right detergents helps prevent worst smells.
Why Odors Form in Washers
Odors originate from moisture, detergent residue, and biofilms that accumulate in damp corners of the drum, door seal, and dispenser. According to Best Washing Machine, these factors are common culprits in home laundry smells. Understanding how odors form helps you target the right areas without over-cleaning. In the quest to learn how to get rid of odors in washing machine, you’ll identify the key sources and start a practical routine that restores freshness and prevents future buildup.
Common Odor Culprits in a Washer
Mildew and mold thrive in moist nooks around the door seal, especially in front-load machines where water can pool in the gasket. Detergent and fabric softener residues cling to the dispenser and drum, feeding biofilm that releases sour or musty smells. Bacteria in hoses and filters, plus towels left inside between cycles, can also contribute. Regular checks help you catch problems early and reduce the time needed to fix odors.
Deep Clean the Drum and Gasket
Start with a thorough wipe of the drum interior using a damp microfiber cloth, paying attention to the corners and the door gasket. Gently lift the rubber seal to inspect for mold and wipe away any grime. Clean the detergent dispenser drawer and its wells, removing soap buildup. This is the foundation of eliminating odors at the source before you run cleaning cycles.
Deodorizing Agents: What Works and What to Avoid
Safe deodorizing options include hot cycles with white distilled vinegar or baking soda. Vinegar helps dissolve mineral deposits and biofilm, while baking soda acts as a mild abrasive and deodorizer. Do not mix vinegar with bleach, as this can release harmful gases; also avoid harsh chemical cleaners that could damage gaskets. For HE washers, check the manual about approved cleaning agents before applying them.
Maintenance Routine to Prevent Odors
Adopt a simple routine that keeps your washer smelling fresh. After each use, wipe the drum and door seal dry and leave the door or lid slightly ajar to promote air flow. Run a monthly hot-water cleaning cycle with vinegar or a baking-soda-based solution, and periodically check and clean the dispenser, filter, and hoses. A tidy laundry space and proper loading practices reduce moisture buildup.
Troubleshooting Persistent Odors
If smells persist after cleaning, inspect for hidden mold in the gasket, drain hose, or behind the dispenser. Check for standing water in the drain and ensure the filter is clean. Run a maintenance cycle again and consider using an enzyme-based cleaner designed for laundry machines. If odors persist after these steps, it’s time to contact a technician.
When to Call a Pro
Severe or recurring odors could indicate a plumbing issue, damaged seals, or mold growth beyond the washer’s accessible parts. A professional can inspect the drain, hoses, and cabinet for leaks or hidden mold and recommend replacement parts if needed. Regular service helps maintain performance and keeps odors from returning.

Steps
Estimated time: about one hour
- 1
Power down and prep
Unplug the washer and remove any loose items from the drum. Gather your cleaning supplies and clear a workspace so you can move safely.
Tip: If you have water connections, consider shutting off the water supply first to avoid leaks. - 2
Wipe the drum and gasket
Moisten a microfiber cloth and wipe the drum interior, paying special attention to the rubber door gasket and folds where moisture hides. Lift the gasket away from the drum to inspect for mold and wipe away any visible buildup.
Tip: Use a second cloth dampened with a mild cleaning solution to rinse residue from hard-to-reach folds. - 3
Clean the detergent dispenser
Remove the dispenser tray if possible and rinse it under warm running water. Scrub soap buildup from wells with a soft brush, and dry before reassembling.
Tip: For stubborn residue, soak the drawer in warm water for a few minutes before scrubbing. - 4
Run a hot cleaning cycle with vinegar
Run the machine on the hottest available cycle with white vinegar to dissolve mineral deposits and biofilm. Do not add laundry, and let the machine complete the full cycle.
Tip: Place a towel around the machine to catch splashes and ensure good ventilation. - 5
Run a second cycle with baking soda
After the vinegar cycle completes, run another hot cycle with baking soda to neutralize odors and remove lingering grime.
Tip: Do not mix baking soda with bleach; run separate cycles if you plan to disinfect afterward. - 6
Finish with air-dry and maintenance
Wipe the drum again, leave the door ajar to air-dry, and check the gasket for moisture. Schedule a monthly maintenance cycle and keep up with routine cleaning.
Tip: Keep the laundry room dry and ensure the washer is not overloaded to prevent odor buildup.
