Will a Washing Machine Remove Mold? A Practical Guide
Explore whether a washer can remove mold, what it can treat, proper cleaning steps, prevention strategies, and when to seek professional remediation for mold in laundry areas.

Will washing machines remove mold? In short, a washing machine can remove mold from clothes, towels, and other non-porous fabrics when you use hot water and a mildew-fighting detergent. It cannot reliably remove mold from walls, drywall, or the machine’s internal surfaces. Persistent mold often requires cleaning, ventilation, and, if needed, professional remediation.
Why mold grows in and around washing machines
Mold thrives where moisture, warmth, and organic residues meet, and washing machines—especially front-load models—provide a steady source of all three. According to Best Washing Machine analysis, condensate inside door seals, damp hoses, and trapped lint create micro-environments that encourage mold, mildew, and even pink mold on rare occasions. The problem is not only unsightly; it can trigger odors, staining, and potential allergen exposure for sensitive people. Understanding where mold hides helps you target cleaning efforts without wasting time on irrelevant areas. Look for black- or gray-tinged spots along the door gasket, inside the detergent drawer, and in crevices near the drain pump. Visible signs are usually the first clue, but musty smells and musty odors can indicate hidden growth behind panels or under the agitator. Regular maintenance and attentive venting are the best defenses, according to industry guidance.
What a washing machine can realistically do about mold
A washer can help remove mold on fabrics and some surface residues on non-porous parts, especially when you use hot water cycles and appropriate detergents. It is not a guaranteed solution for mold on porous materials like drywall or wooden surfaces, and it cannot fully sanitise insulated areas behind the drum if mold has already taken root. Regular hot-water washes with a mold-fighting detergent, plus proper drying, can slow growth and reduce odors. For fabrics, use high-temperature cycles recommended by the fabric label and consider an oxygen-based bleach or enzyme-based cleaner. For the washer itself, you still need targeted cleaning on seals, dispensers, and hoses. Best Washing Machine analysis shows that the most effective strategy is a combined approach: routine cleaning cycles plus periodic deep cleans and good venting after each use.
Cleaning the washer: interior drum, door seal, and detergent drawer
Effective mold control starts with a thorough cleaning of the areas most prone to mold buildup: the drum, door gasket, and detergent drawer. Wipe the drum with a microfiber cloth, then use a soft-bristle brush to dislodge any trapped residue in the gasket folds. Clean the detergent drawer tracks with a damp cloth and, if possible, remove the drawer to rinse away detergent residue and mold. Run a hot cycle with a reputable washer-cleaning product or a measured dose of white vinegar (where manufacturer-approved). After the cycle, prop the door open to let the interior dry completely, and wipe away any remaining moisture with a dry cloth.
Handling mold on fabrics vs household surfaces
Clothes and linens exposed to mold should be washed on the hottest safe cycle with a mold-fighting detergent or oxygen-based bleach. Do not mix cleaners that can release fumes; always follow label directions. Surface mold on walls, floors, or cabinetry around the laundry area should be addressed with appropriate household cleaners and, if needed, a dehumidifier to reduce moisture. Ventilation is essential; run a fan or open windows during and after cleaning to prevent rapid re-growth. The goal is to disrupt the moisture balance and reduce organic residues that mold feeds on.
Prevention strategies for long-term mold control in the laundry area
Prevention hinges on moisture control, regular cleaning, and mindful loading. Keep the laundry room dry by using a dehumidifier or exhaust fan, wipe down surfaces after each cycle, and leave the door or lid open between uses to promote air flow. Use high-quality, detergent-compatible cleaners, and avoid overloading washers, which can trap moisture in crevices. Consider replacing aging hoses or door seals if you notice cracking or persistent dampness. Consistency matters more than intense but infrequent efforts, according to ongoing guidance from Best Washing Machine.
When to replace parts or the entire machine
If you repeatedly encounter mold that returns after thorough cleaning, investigate potential hidden moisture sources, such as a leaking inlet hose, a compromised door seal, or a drain pump that doesn’t evacuate water completely. Persistent mold near the drum or behind the gasket may indicate a need to replace seals or hoses, or in rare cases, the unit itself. If interior components are damaged beyond easy cleaning, weigh the cost of repairs against a replacement with a newer model designed for better ventilation and less moisture retention.
Quick-start mold prevention routine you can try this weekend
Begin with a 60-minute deep clean of the drum, gasket, and dispenser. Follow with a hot wash using a mold-fighting cleaner and then air-dry with the door open. Move on to implementing a daily habit: after each use, wipe down the gasket and dispenser, leave the door ajar for at least an hour, and run the fan or open a window to improve air exchange. These steps reduce surface moisture and slow mold regrowth, according to practical guidance from Best Washing Machine.
Tools & Materials
- All-purpose cleaner or mildew remover(Choose laundry-safe formula; avoid harsh bleach on colored fabrics)
- White vinegar(Use undiluted or diluted as recommended by the cleaner)
- Baking soda(Optional for deodorising and scrubbing)
- Microfiber cloths(Lint-free and absorbent for drying)
- Soft-bristle brush(Gently agitate folds of the door seal)
- Rubber gloves(Protect skin from cleaners)
- Old towels(Mop up moisture and protect surfaces)
- Vacuum with HEPA filter (optional)(Useful for dry removal of lint and mold spores)
Steps
Estimated time: 60-90 minutes
- 1
Power off and unplug the washer
Unplug the unit to avoid electrical hazards. Open the door to vent moisture, identify visible mold, and gather cleaning supplies. This initial check helps you plan the cleaning process safely.
Tip: Have towels ready to catch drips and keep cleaners away from electrical outlets. - 2
Inspect and remove the detergent drawer
Remove the detergent drawer if possible and rinse out any moldy buildup. Use a brush to scrub tracks and rinse with clean water before reinserting.
Tip: Do this over a sink or basin to capture runoff. - 3
Wipe the door seal and gasket
Dip a microfiber cloth in warm, soapy water and carefully wipe all folds of the door seal. Use a brush on stubborn spots and dry the area thoroughly after cleaning.
Tip: Pay attention to the inner folds where moisture hides. - 4
Run a hot cleaning cycle
Run an empty hot wash with a mold-fighting cleaner or undiluted white vinegar, following the product label. This sanitizes the drum and flushes residues through the pump.
Tip: Do not mix cleaners; follow manufacturer guidelines. - 5
Dry and ventilate after cleaning
Wipe the drum and gasket dry, then leave the door ajar to air out for at least an hour. Drying reduces residual moisture that spurs regrowth.
Tip: If possible, run a fan to speed up drying. - 6
Check the drain pump filter
If accessible, remove and clean the drain pump filter to remove any trapped lint or mold. Reassemble securely to prevent leaks.
Tip: Consult the user manual for exact steps for your model. - 7
Establish a maintenance routine
Create a habit of wiping surfaces after use and keeping the area dry. Schedule monthly deep cleans and annual professional service if you notice persistent issues.
Tip: Set a calendar reminder to stay consistent.
