Before You Start

Safety comes first: unplug electrical connections if you’re inspecting internal parts, and avoid splashing water around electrical outlets. Run the washer on the hottest setting available to maximize mold-killing steam. Schedule maintenance when you have 60–90 minutes free. Cautions: do not mix cleaners with bleach and ventilate the area to reduce fumes. If your washer is very moldy or shows persistent odor after maintenance, a professional service may be needed.

Step-By-Step: How To Remove Mold In Washer

Open the washer door and inspect the rubber door seal for visible mold or mildew. Wipe the seal with a damp cloth, paying attention to folds and creases.
Remove and clean the detergent drawer. Soak it in warm, soapy water, then scrub away residue that feeds mold growth.
Run a cleaning cycle using Affresh washer cleaner tablets. Place one tablet in the drum and run a hot cycle according to package directions.
If you prefer, run a second cycle with OxiClean washing machine cleaner tablets for a boost, following the same hot-cycle method.
After the cycles complete, wipe the drum interior with a microfiber cloth and inspect the gasket again for any remaining mold. Use the mold and mildew remover spray to target spots that resist cleaning.
Fill the drum with hot water and add a cup of white vinegar. Run a full hot wash to neutralize any lingering odor and kill bacteria.
Dry the interior and door seal thoroughly with a clean towel. Leave the door ajar after each load to promote air flow and prevent future moisture buildup.
Repeat monthly or after heavy use to maintain a mold-free washer. If you notice recurring odor, consider a more frequent cleaning schedule or a professional diagnosis for hidden mold.

Troubleshooting

Symptom	Likely Cause	Fix	Prevention
Musty odor persists after cleaning	Hidden mold in gasket or hoses	Thoroughly spray and wipe seals; run additional cleaning cycles	Keep door open between washes; use monthly cleaning cycles
Visible mold on gasket	Moist environment and debris buildup	Clean with mold-removal spray, dry completely	Regularly inspect and wipe seals
Water not draining properly	Blocked filter or hose kinks	Check drain pump filter and hoses	Clear clogs during routine maintenance
Detergent residue after wash	Overuse of detergent or clogged dispenser	Clean dispenser; use recommended amounts	Switch to high-efficiency detergent if applicable

Common Mistakes

Using bleach leftover from household cleaning can damage gaskets; avoid mixing with ammonia-based products.
Skipping the drying step after cleaning leaves moisture for mold to return.
Ignoring odors between loads; consistent maintenance reduces buildup.

Tip: Keep the washer door slightly ajar after each use to improve air circulation and speed up drying.

Tips For Best Results

Use the correct cleaners: Affresh tablets or OxiClean tablets are formulated to break down residue that fuels mold growth.
Choose hot water cycles where possible to maximize mold-killing efficacy.
Target seals and drawers with a dedicated mold-removal spray for stubborn spots.
Schedule routine cleanings every 1–3 months based on usage, climate, and visible moisture.
Keep the surrounding laundry area well-ventilated to reduce humidity.

Call A Professional

Call a pro if you notice persistent mold growth despite cleaning, recurring odors after multiple treatments, or if there are signs of leaks, unusual noises during cycles, or electrical concerns around the unit. Do not attempt invasive disassembly if unfamiliar with appliance repairs. A licensed technician can assess hidden mold behind panels and ensure safe operation.

FAQ

How often should I clean my washer to prevent mold?

Most homes benefit from a cleaning cycle every 1–3 months, depending on usage and climate.

Can I use bleach to remove mold in my washer?

Bleach can help, but avoid mixing with ammonia or other cleaners. Use dedicated washer cleaners as directed.

Is front-loading or top-loading more prone to mold?

Front-loading washers are more prone due to door seals and moisture retention; regular cleaning and drying help mitigate this.

What’s the best way to dry the interior after cleaning?

Leave the door ajar and run a short hot cycle with the drum empty to dry residual moisture.

Are Affresh and OxiClean safe for all washers?

Yes, when used as directed, these products are designed for most household washers. Always check the user manual for model-specific guidance.

Can I remove mold without moving the washer?

Yes, most cleaning steps can be performed with the unit in place, but ensure good ventilation and access to all areas including the gasket and detergent drawer.

What if mold reappears after cleaning?

Reassess moisture levels in the laundry area, re-check seals for damage, and consider a humid environment control plan in addition to a stricter cleaning schedule.

Buying Guide

When choosing products and planning maintenance to prevent washer mold, consider size, noise level, energy efficiency, controls, and placement. For many homes, front-loading washers are popular for space efficiency but require meticulous seal cleaning; top-loaders may be easier to access for maintenance. Look for high-efficiency (HE) models and energy-star-rated units to balance running costs with cleaning performance. For cleaners, choose trusted brands like Affresh or OxiClean designed for washing machines, and keep a dedicated mold-removal spray on hand for quick spot treatments. Store supplies in a cool, ventilated area near the laundry space to encourage regular use. Consistency matters more than intensity; a simple monthly routine tends to prevent mold buildup effectively.
