How to Eliminate Musty Smell in Your Washing Machine: Practical Tips & Preventative Measures

Understanding the Musty Smell Issue

When your washer machine starts emitting that unpleasant, musty odor, it can be quite bothersome. Identifying the root cause of this problem is the first step towards banishing the smell for good.

Excess moisture in your washer is often the main culprit behind that musty smell. The warm and damp environment inside the machine becomes an ideal breeding ground for mold and mildew.

Leaving the door closed between washes can worsen the issue as it traps moisture inside, exacerbating the growth of odor-causing agents. Lingering soap residue can also contribute to the formation of that unwanted smell.

Regularly cleaning your washer and adopting some simple habits can significantly reduce the musty odor. Stay tuned for actionable tips on how to get your washer smelling fresh again.

Common Causes of Musty Smell in Washer Machine

If your washing machine has a musty smell, excess moisture in the washer could be the culprit. This creates the perfect environment for mold and mildew to thrive, leading to that unpleasant odor. Another common cause is lingering soap residue, which can contribute to the musty smell. Leaving the washer door closed between uses can also worsen the problem by trapping moisture inside.

Cleaning the Washer Machine Drum

To tackle the musty smell in your washing machine, Cleaning the Washer Machine Drum is essential. Here’s how you can do it effectively:

  • Run a Hot Water Cycle: Start by running a hot water cycle without any laundry or detergent. The heat helps loosen any residue in the drum.
  • Add White Vinegar: Pour two cups of white vinegar into the detergent dispenser or directly into the drum. The acidity of vinegar helps break down mold and mildew.
  • Use Baking Soda: Sprinkle one cup of baking soda into the drum. Baking soda acts as a natural deodorizer, eliminating any lingering odors.
  • Scrub the Drum: Grab a clean cloth or sponge and scrub the inside of the drum to dislodge any grime or residue.
  • Wipe Down Seals and Gaskets: Don’t forget to clean the seals and gaskets around the door. These areas can harbor mold and contribute to the musty smell.

  • Use Vinegar Solution: Create a mixture of equal parts white vinegar and water. Pour this solution into the detergent dispenser and run a hot water cycle.
  • Scrub the Drum: After the cycle, dip a clean cloth in the vinegar solution and scrub the inside of the drum to dislodge any remaining residue.
  • Clean Seals and Gaskets: Wipe down the door seals and gaskets with the vinegar solution to ensure thorough cleaning.
