A washing machine that smells like mildew is a common problem that many homeowners encounter. This unpleasant odor can transfer to your freshly cleaned clothes and become a persistent issue if not addressed promptly. In this guide, we will explore the causes of this problem and provide step-by-step solutions to eliminate the mildew smell from your top loading washing machine.
Causes of Mildew Smell:
- Residue Buildup:
- Over time, detergent, fabric softener, and dirt can accumulate in various parts of the washing machine, providing a breeding ground for mildew and bacteria.
- Low-Temperature Washes:
- Washing clothes at low temperatures can fail to kill the bacteria and mold present in the machine, leading to a lingering mildew smell.
- Moisture Retention:
- The design of some top loading machines can trap moisture in the drum or seals, allowing mold and mildew to thrive in these damp conditions.
- Improper Maintenance:
- Neglecting regular cleaning and maintenance of the washing machine can exacerbate mildew issues.
Steps to Eliminate Mildew Smell:
- Clean the Drum:
- Empty the machine and run a hot water cycle with no clothes. Add two cups of white vinegar to the detergent dispenser. Vinegar is an effective natural cleaner that helps eliminate mildew and bacteria.
- Clean the Seals and Gaskets:
- Use a solution of equal parts water and vinegar to wipe down the rubber seals and gaskets around the door. Pay extra attention to any visible mold or mildew.
- Clean the Detergent Dispenser and Filter:
- Remove and clean the detergent dispenser and any filters or lint traps your machine may have. Ensure there’s no residue or debris left behind.
- Run a Hot Water Cycle with Baking Soda:
- After the vinegar cycle, run another hot water cycle, this time adding half a cup of baking soda to the drum. Baking soda helps neutralize odors.
- Regularly Use Hot Water and High Spin Speeds:
- Whenever possible, wash your clothes in hot water, and use the highest spin speed. This helps to remove more bacteria and moisture from the machine.
- Leave the Door Open:
- After each use, leave the washing machine door open to allow air to circulate and prevent moisture buildup.
- Use the Right Detergent:
- Choose a high-efficiency (HE) detergent, as it is designed to work effectively in low water volumes and can help reduce residue buildup.
- Inspect and Clean Drain Pump:
- Occasionally, check the drain pump for debris, which can contribute to odors. Refer to your machine’s manual for instructions on how to access and clean it.
- Consider a Washing Machine Cleaner:
- Periodically, use a commercial washing machine cleaner according to the manufacturer’s instructions to remove stubborn mildew and bacteria.
Preventive Measures:
- Regular Maintenance:
- Develop a routine for cleaning your washing machine to prevent future mildew issues.
- Use Hot Water Washes:
- Whenever possible, opt for hot water washes to help kill bacteria and mold.
- Dry the Drum:
- After each use, wipe down the drum and seals with a clean, dry cloth to remove excess moisture.
- Proper Ventilation:
- Ensure your laundry room has good ventilation to reduce humidity and moisture buildup.
Additional Tips and Considerations:
- Check for Hidden Pockets:
- Before loading clothes into the machine, always check pockets for items like tissues, paper, or other debris that can contribute to residue buildup.
- Use Natural Odor Absorbers:
- To keep the washing machine smelling fresh between washes, place a small bowl of baking soda or activated charcoal inside the drum. These natural odor absorbers can help eliminate any lingering odors.
- Inspect and Clean the Water Inlet:
- Over time, minerals and debris can accumulate in the water inlet filters and hoses, affecting water quality. Regularly inspect and clean these components to ensure clean water enters the machine.
- Consider a Dehumidifier:
- If your laundry room is particularly humid, using a dehumidifier can help reduce moisture levels, preventing mold and mildew growth.
- Use Bleach Sparingly:
- While bleach can effectively kill mold and mildew, it should be used sparingly, as excessive use can damage your machine’s components and clothing. Consult your machine’s manual for specific recommendations regarding bleach usage.
- Inspect the Drainage System:
- Ensure that your washing machine is draining properly. If water accumulates in the drum or around the machine, it can contribute to mold growth. Check the drainage hose for any obstructions and ensure it’s properly installed.
- Regularly Replace Rubber Seals:
- Rubber seals and gaskets can degrade over time. If you notice persistent mildew in these areas, consider replacing them to ensure a tight seal.
- Professional Service:
- If the mildew smell persists despite your efforts, consider contacting a professional appliance repair technician. There could be underlying issues with your washing machine that require expert attention.
- Read the User Manual:
- Always refer to your washing machine’s user manual for specific cleaning and maintenance instructions provided by the manufacturer.
- Adjust Your Laundry Routine:
- If the mildew smell is a recurring issue, consider adjusting your laundry routine. Use shorter cycles when appropriate and try to minimize the time clothes spend in the damp drum after washing.
- Inspect the Water Softener:
- If your home has hard water, it can leave mineral deposits in your washing machine, contributing to odors. Check and maintain your water softener if necessary.
- Use Vinegar Rinse:
- Periodically, add a cup of white vinegar to the final rinse cycle. This can help remove detergent residues and leave your clothes and washing machine smelling fresher.
