How to Remove Washing Machine Odor Safely

Washing machine odor: identify the problem first

A washing machine odor is usually a musty, sour, or stale smell that returns after a load. Common contributors include detergent or fabric-softener residue, body oils and soil left behind by laundry, standing water, and damp areas that do not dry between cycles. Front-loaders are especially likely to retain moisture in the door gasket and dispenser area, but top-loaders can also develop residue and odor around the tub, lid, dispenser, or drain system.

This routine covers normal cleaning of accessible washer surfaces: the drum, door gasket, dispenser, lid, and other areas identified in the owner’s manual. It does not cover a sewer-gas smell, a burning or electrical odor, a persistent leak, a blocked internal drain, contaminated floodwater, or mold growth behind panels. It also does not replace the washer manufacturer’s instructions. If the odor smells like gas, burning insulation, or overheated plastic, stop using the machine and contact a qualified professional or the manufacturer.

Prepare for washing machine odor removal

Read the owner’s manual before starting. Confirm whether the washer has a dedicated Clean Washer, Tub Clean, or Drum Clean cycle, whether it has a removable drain filter, and which washer-cleaning products are approved. Some manufacturers specify a commercial washer cleaner; others provide instructions for diluted liquid chlorine bleach. Do not combine methods in the same cleaning session unless the manufacturer explicitly directs you to do so.

Gather clean microfiber cloths, a soft toothbrush or soft nylon brush, a small basin, and the approved washer-cleaning product. Use gloves if your skin is sensitive to detergents or cleaners. Open a window or run the room’s exhaust fan when the product label calls for ventilation. Remove all clothing from the washer before cleaning.

Step-by-step routine

1. Inspect the source of the odor.

   Smell the gasket, dispenser, drum, and floor area around the washer separately. Look for pooled water, lint, gray or black residue, detergent buildup, and signs of a drain problem. Do not scrape aggressively or use a metal tool on the gasket or coated surfaces. If you see extensive growth in an inaccessible area, stop and arrange service rather than forcing the seal apart.

2. Clean the dispenser and its housing.

   Remove the detergent, bleach, or softener drawer if the manual permits removal. Rinse it with warm water and brush away softened residue. For stubborn buildup, allow the removable drawer to soak in warm water, then rinse thoroughly. Wipe the cavity and the dispenser housing with a damp cloth or soft brush. Do not pour concentrated cleaner into small openings unless the manual specifically says to do so, because residue can be pushed farther into the machine.

3. Wipe the door gasket or lid area.

   On a front-load washer, gently pull back each fold of the rubber gasket and remove lint, hair, coins, and visible residue. Wipe with a cloth dampened with plain water or a manufacturer-approved cleaner, then wipe again with clean water. Dry the folds carefully. Do not use abrasive powders, sharp tools, or undiluted bleach on the gasket unless the manufacturer expressly permits it; harsh or incompatible chemicals can damage elastomeric parts.

   On a top-load washer, wipe the underside of the lid, the rim around the tub, and the area around the dispenser. Keep liquid away from the control panel and electrical openings.

4. Clean the drum using the approved cycle.

   Run the washer’s Clean Washer, Tub Clean, or equivalent cycle with the approved washer cleaner and the amount stated on its label. If the machine has no cleaning cycle, follow the manufacturer’s manual for the hottest suitable empty cycle and cleaning product. Never add clothing, detergent, or fabric softener during this maintenance cycle.

   Do not combine a washer cleaner with vinegar, citric acid, ammonia, or chlorine bleach. Acidic cleaners and bleach can react and release hazardous gas. If the manufacturer’s instructions call for bleach, use only the specified bleach type and amount, keep the room ventilated, and run the complete rinse or cleaning cycle required by the manual.

5. Check the accessible drain filter or pump filter.

   Only clean this part if your model has a user-accessible filter and the manual provides instructions. Turn off the washer as directed, protect the floor with towels or a shallow container, and expect residual water. Remove lint and small objects, rinse the filter if the manual allows it, and reinstall it securely. Never remove a panel to reach an internal filter or pump unless you are qualified to do so.

6. Rinse and dry the accessible surfaces.

   After the cleaning cycle, inspect the drum and gasket. If the manual calls for an additional rinse, run it. Wipe away remaining moisture from the gasket, door, lid, drum rim, and dispenser. Leave the dispenser drawer partially open and the washer door or lid open when safe to do so. Keep the opening blocked from children and pets, and follow the manufacturer’s guidance if the washer is in a location where an open door creates a hazard.

7. Change the habits that allow odor to return.

   Remove finished laundry promptly. Use only the detergent amount and type recommended for the washer and load; excess detergent can leave residue. Avoid routinely adding fabric softener beyond the label amount. After wet loads, leave the gasket and surrounding surfaces able to dry, and periodically repeat the manufacturer’s washer-cleaning cycle according to its care instructions.

When to stop and call for service

Stop cleaning and contact the manufacturer or a qualified appliance technician if the odor remains after a complete manufacturer-approved cleaning cycle and a second inspection. Service is also appropriate for repeated standing water, slow draining, a damaged or loose gasket, water beneath the appliance, an odor from the wall outlet or cord, unusual heat, smoke, or a burning smell.

Do not use stronger chemicals to chase a persistent odor. A recurring smell can indicate a drain, venting, pump, seal, or installation problem that surface cleaning will not correct. If sewage odor is coming from the standpipe or drain rather than the washer, a plumbing professional may be needed.

FAQ

Can I pour vinegar into a smelly washing machine?

Vinegar is an acid and should not be mixed with chlorine bleach or ammonia. More importantly, the washer manufacturer may not approve it for routine care, and repeated exposure to acidic products may be unsuitable for some seals or finishes. Use the cleaning product and method specified in the owner’s manual instead.

Should I use bleach for washing machine odor?

Only when the manufacturer and bleach label allow it. Use the stated amount, provide ventilation, and never combine bleach with vinegar, citric acid, ammonia, or another cleaner. A washer-cleaning product may be the manufacturer’s preferred option.

Why does the odor return after cleaning?

The source may be trapped moisture, excess detergent, an unclean dispenser, residual water in a filter, or a drainage problem. Dry accessible surfaces after use and check the manual for filter and maintenance instructions. Persistent odor after those steps needs diagnosis rather than stronger chemicals.

Source note

This routine follows CDC guidance to clean surfaces before disinfecting when disinfection is needed and to use products according to their labels. Washer-specific steps should be checked against the current owner’s manual because cycle names, filter access, seal materials, and approved cleaners vary by model. The Whirlpool and American Cleaning Institute references provide manufacturer and industry guidance for washer maintenance; they do not replace instructions for your specific appliance.
