Musty odors in a washing machine are a common hassle for many American households. Poor drainage, lingering detergent residue, and damp interiors can create a sour scent that transfers to clothes. This guide provides practical, step-by-step methods to freshen both front-load and top-load washers, using common tools and proven cleaners.
Quick Answer
Quick method: run a hot water cycle with a trusted washer cleaner, scrub the tub and seals, and leave the door or lid ajar to air dry. For stubborn smells, repeat with a second cycle using baking soda or vinegar followed by a dedicated cleaning tablet.
What You’ll Need
- Washing machine tub cleaning brush set
- Front-load washer gasket scraper silicone
- Washing machine cleaning kit with tub cleaner tablets
- Odor removing washer cleaner spray professional grade
- Drum cleaning brush for washer 360-degree
Before You Start
Prepare a clear work area around the washer. Unplug the machine before disassembly or vigorous scrubbing. If your unit is in a damp basement, consider increasing airflow with a fan during cleaning. Time estimates vary: plan 60–90 minutes for a thorough reset, and up to 3 cycles for stubborn odors. Always follow manufacturer guidelines for your specific model to avoid voiding warranties.
Step-By-Step: How To Eliminate Musty Smell In Washer
- Remove laundry and run a quick empty cycle to warm the interior. Use the hottest setting your machine allows to help loosen buildup.
- Apply a tub cleaner tablet or a dedicated washer cleaner spray along the tub edges. Let it sit for the time recommended by the product before starting the cycle.
- Scrub the drum interior with the drum cleaning brush for washer 360-degree to remove soap scum and mineral deposits. Pay attention to corners and crevices where mold can form.
- Inspect the front-load washer gasket. Use the gasket scraper silicone to remove hair, grime, and residue pooled in folds. Wipe dry with a microfiber cloth.
- Run another hot water cycle with just water or with a small amount of baking soda to neutralize lingering odors. This helps remove any cleaner residue from the drum and seals.
- Ventilate the door or lid to promote drying. After the cycle, leave the door slightly ajar and wipe the door seal dry to prevent moisture buildup.
- If odors persist, use the odor removing washer cleaner spray professional grade around the tub edge and gasket. Allow contact time, then run a fresh rinse cycle.
- Recheck the drum and gasket for any remaining residue. Repeat steps as needed for stubborn smells, ensuring the machine dries thoroughly after each cycle.
- Regular maintenance: adopt a monthly routine with a cleaning kit and a quick hot wash to prevent odor recurrence.
- Store cleaning tools in a dry location and avoid leaving damp cloths or towels inside the machine after use.
Troubleshooting
| Symptom | Likely Cause | Fix | Prevention |
|---|---|---|---|
| Musty smell persists after cleaning | Hidden mold in folds of gasket | Re-scrub with gasket scraper and repeat a hot wash with cleaner | Keep door slightly open between uses |
| Soap scum buildup on drum | Overuse of detergent or mineral-rich water | Switch to appropriate detergent amount and run chlorine-free cycles | Use a maintenance cycle monthly |
| Damp towels or clothes smell after washing | Inadequate drying | Air out the drum after cycles; dry gasket | Leave door ajar for a few hours after washing |
| Bad odor returns quickly | Moist environment inside machine | Increase air circulation and run periodic cleaning | Regularly clean seals and drain pump area |
Common Mistakes
- Using too much detergent can leave residue that fosters odor.
- Skipping the gasket area cleaning, where mold often hides.
- Relying on a single cleaning cycle for a strong musty smell.
These missteps can reduce cleaning effectiveness and extend odor problems. A systematic approach yields better, longer-lasting freshness.
Tips For Best Results
- Pair tub cleaners with a steam-assisted option if your washer supports it for deeper cleaning.
- Schedule monthly maintenance to prevent odor buildup rather than reacting to a strong smell.
- Store cleaning brushes and sprays in a dry, ventilated area to maintain their effectiveness.
- Consider using a filter or lint trap cleaner if your model has one, to keep drainage clear.
Call A Professional
Consider contacting a technician if you notice persistent mold growth, persistent leaks, or unusual noises after thorough cleaning. Stop signs include ongoing water leakage, damaged door seals, or electrical concerns. A professional can assess seals, drainage lines, and the drum drive for issues beyond routine maintenance.

Effective odor control relies on selecting the right tools and cleaners for your machine. Consider the following factors to ensure you pick the best options for a lasting refresh.
- Size and compatibility: Ensure the tub cleaning brush set and gasket scraper are appropriate for your washer’s drum diameter and gasket design (front-load vs. top-load).
