How to Get Mildew Out of a Washing Machine: A Complete Guide
Mildew in your washing machine can turn fresh laundry into a musty-smelling disappointment. Not only does mildew leave an unpleasant odor, but it can also cause stains and reduce the efficiency of your washer. Luckily, removing mildew is straightforward—and with a little care, you can keep your machine fresh and clean all year round.
Understanding Why Mildew Grows in Washers
Washing machines, especially high-efficiency and front-loading models, create a warm and damp environment—the perfect breeding ground for mildew and mold. Detergent and fabric softener residue, dampness from leftover water, and trapped lint often make matters worse.
Without regular cleaning, you’ll notice:
– Musty odors in your laundry
– Black or gray stains on the rubber door seal (gasket)
– Residue in detergent dispensers and inside the drum
Knowing why mildew occurs is the first step to stopping it.
Step-by-Step: Removing Mildew From Your Washing Machine
Follow these simple steps to freshen up your washer and say goodbye to mildew for good.
1. Gather Your Supplies
Start by collecting everything you’ll need:
– White vinegar or bleach
– Baking soda
– Clean microfiber cloths or sponges
– Old toothbrush
– Spray bottle
– Rubber gloves (optional but recommended)
– Small bowl
Vinegar and baking soda are great all-natural cleaners. For persistent mold, bleach may be necessary, but always use it with care and never mix it with vinegar.
2. Clean the Washer Door and Rubber Seal
The rubber seal (gasket) around the door is a hotspot for mildew, especially in front-loading machines.
How to Tackle Mold on the Gasket:
- Mix equal parts white vinegar and water in a spray bottle.
- Spray liberally around and inside the folds of the gasket.
- Let the solution sit for several minutes to break down residue.
- Use a toothbrush to scrub away any mold, debris, or build-up.
- Wipe clean with a damp microfiber cloth.
- For stubborn stains, repeat with a bit of baking soda paste (mix baking soda and water).
Be sure to pull back the seal and check between folds for hidden grime.
3. Clean the Dispensers
Detergent and fabric softener dispensers can harbor mildew and residue.
Steps:
1. Remove the dispensers from the machine (most models allow you to slide them out).
2. Soak in hot, soapy water.
3. Scrub with a toothbrush, paying attention to corners and crevices.
4. Rinse and dry thoroughly before returning them to the washer.
4. Run a Cleaning Cycle
Now that the visible areas are addressed, it’s time to deep-clean the drum and internal parts.
Using Vinegar and Baking Soda:
- Pour two cups of white vinegar directly into the drum.
- Add half a cup of baking soda.
- Run the washer on the hottest, longest cycle with no clothes inside.
Using Bleach for Tough Jobs:
- Pour one cup of bleach into the detergent dispenser (never mix bleach with vinegar!).
- Run the hottest, longest cycle.
- When finished, run a second empty cycle with just water to rinse away any leftover bleach.
5. Wipe Down and Leave to Dry
After the cleaning cycle:
– Open the door and let the interior air dry completely.
– Wipe down the inside of the drum, door, and any remaining damp areas with a dry cloth.
Letting the machine air out helps prevent mildew from coming back.
6. Clean the Machine’s Filter (If Applicable)
Some washers have a drain filter that can trap dirt, lint, and even socks! Mildew can thrive here too.
Easy steps:
1. Locate the filter (usually at the bottom front).
2. Place a towel and shallow pan underneath in case of water leaks.
3. Unscrew or slide out the filter.
4. Clean out any debris and rinse under hot water.
5. Replace the filter securely.
Preventing Mildew in the Future
A little maintenance goes a long way! Here’s how to keep your washer mildew-free:
- Leave the washer door and detergent drawer open after each load to promote air flow.
- Use the right amount of detergent—excess can lead to residue and mildew formation.
- Remove wet laundry promptly after the cycle ends to stop moisture from lingering.
- Wipe the rubber seal, gasket, and inside of the door weekly.
- Run a monthly cleaning cycle with vinegar or a commercial washing machine cleaner.
- Check and clean the filter every couple of months if your machine has one.
Building these habits will keep your laundry smelling fresh and your machine running smoothly.
Troubleshooting: Common Challenges
Sometimes mildew problems are stubborn. Here are some challenges you might face, and how to resolve them:
Stubborn Black Mold on the Seal
If regular vinegar cleaning doesn’t remove black stains, apply a paste of baking soda and water directly onto the stains. Let it sit for 30 minutes, then scrub away with a brush. For severe cases, use a diluted bleach solution (one part bleach to ten parts water) but protect your skin and ventilate the area.
Persistent Odor
If musty smells linger even after cleaning, try repeating the cleaning cycle or using a washing machine cleaning tablet. Check for clogs in the filter or drain hose.
Recurring Mildew Buildup
Frequent mildew means moisture is lingering too long. Make sure you’re airing the machine out after every cycle and using the right detergent for your washer type.
Sensitive Allergies
Mildew spores can irritate allergies. Wear gloves and a mask while cleaning, and dry the area thoroughly afterward.
Practical Tips for Best Results
- If you have a front-loader, always wipe the door gasket after use.
- Clean the detergent drawer monthly to prevent build-up.
- If you notice suds remaining after a cycle, you might be using too much detergent or one not formulated for your washer.
- For extra freshness, add a few drops of essential oil to the vinegar cleaner.
- Keep a cleaning reminder calendar—monthly cleans help avoid big problems.
The Benefits of a Clean Washer
Taking the time to clean your washing machine offers real rewards:
- Laundry smells fresher, with no lingering musty odor.
- Clothes are cleaner, since residue isn’t being redeposited.
- Less likelihood of buildup that could lead to mechanical issues.
- Reduced spread of allergens in your home.
- The machine lasts longer and runs more efficiently.
A little elbow grease goes a long way in keeping your washer, your clothes, and your home at their best.
Frequently Asked Questions (FAQs)
How often should I clean my washing machine to prevent mildew?
You should aim to clean your washing machine at least once a month. However, if you notice a musty odor or visible mildew before then, clean it right away.
Is it safe to use bleach or vinegar to clean my washing machine?
Yes, both bleach and white vinegar are safe and effective for cleaning your washer. However, never use them together or simultaneously, as combining them can create harmful fumes.
Can mildew in the washing machine make my clothes smell bad?
Absolutely. Mildew growth inside your machine often causes laundry to come out with a moldy or musty odor. Regular cleaning will prevent this problem.
Does mildew form more in front-loading or top-loading washers?
Front-loading machines are more prone to mildew, especially around the rubber door seal, because they tend to trap more moisture. Top-loaders still need regular cleaning but usually have fewer issues.
What should I do if the mildew keeps coming back quickly?
Make sure you’re leaving the washer door open between uses, using the correct amount of detergent, and routinely wiping down the gasket and drum. If your area is very humid, consider running a fan or dehumidifier near the laundry area.
By following these steps and tips, you’ll keep mildew at bay—ensuring your washing machine smells as fresh as your clean clothes. Regular care not only saves you trouble but also helps extend the lifespan of your machine.
