It happens far too often: you finish a wash cycle, open the washing machine door, and are met with an unpleasant, musty smell. It may seem paradoxical, given that most of us use fragrant detergents and softeners. You expect your clothes to come out smelling fresh and clean, but sometimes the exact opposite happens. The culprit isn’t your laundry—it’s the washing machine itself.

A closed drum with limited airflow can easily become a breeding ground for damp, stale odors. Over time, this smell transfers to the clothes, leaving them with that unmistakable “laundry funk” despite regular washing. Fortunately, this is far from an unsolvable problem. With a simple and highly effective trick, you can restore freshness to your laundry and ensure your clothes smell delightfully clean after every wash.

Essential Precautions Before Using Odor-Fighting Products

Before reaching for any product to eliminate odors, it’s important to address the root cause. Regular maintenance and deep cleaning of your washing machine are crucial for proper functioning and odor prevention. Even if the machine appears clean on the surface, hidden areas like the detergent drawer, drum seals, and small crevices often accumulate residue that eventually produces foul odors.

Experts recommend cleaning these components at least once a month. This includes:

  • Detergent Drawer: Remove and wash thoroughly to eliminate soap buildup.

  • Drum: Clean the drum and the rubber seal to remove mold, soap scum, and trapped dirt.

  • Hidden Areas: Check hoses, filters, and other small areas where residue may collect.

By maintaining these key parts of your machine, you’ll prevent musty smells from returning and enhance the efficiency of every wash.

The Simple Trick: Citric Acid

One of the most effective methods to eliminate persistent odors is using citric acid. Unlike many chemical cleaners, citric acid is natural, eco-friendly, and highly effective. Here’s how to use it:

  1. Prepare the Solution: Dissolve 150 grams of citric acid in one liter of water.

  2. Add to the Drum: Pour the solution directly into the washing machine drum, not the detergent drawer.

  3. Run a Hot Cycle: Start a full wash cycle on the hottest setting without any clothes inside.

The citric acid works wonders by breaking down residue, neutralizing odors, and restoring your washing machine to a fresh state. This method ensures that every future load of laundry comes out smelling clean and fresh.

Alternative: White Vinegar

If citric acid is unavailable, white wine vinegar can also be used as an effective odor remover. Vinegar is a natural deodorizer and disinfectant. To use:

  1. Pour two cups of white vinegar directly into the washing machine drum.

  2. Run a hot wash cycle without clothes.

White vinegar will neutralize musty smells and help remove mineral deposits and residue in the drum. However, it’s worth noting that vinegar has a slightly higher environmental impact compared to citric acid. For the most eco-friendly option, citric acid is preferable.

Why This Method Works

Both citric acid and vinegar target the underlying causes of odors. They break down accumulated residues, kill bacteria and mold, and neutralize unpleasant smells. Unlike synthetic chemical cleaners, these natural ingredients are safe for your washing machine and for the environment.

In addition, performing an empty wash cycle with these products enhances their effectiveness. It ensures that the cleaning solution reaches all corners of the drum, including hidden seals and pipes, leaving the machine thoroughly sanitized.

Regular Maintenance for Fresh Laundry

Even with citric acid or vinegar, preventive maintenance is essential to avoid future musty odors. Here are some tips for keeping your washing machine and clothes smelling fresh:

  • Leave the Door Open: After every wash, leave the door slightly ajar to allow air circulation and prevent dampness from lingering in the drum.

  • Clean Filters and Seals Monthly: Regularly remove and clean these areas to prevent mold and residue buildup.

  • Avoid Overusing Detergent: Excess detergent can leave residues that trap odors. Use the recommended amount for your laundry load.

  • Perform Monthly Maintenance Washes: Run an empty hot cycle with citric acid or vinegar monthly to keep the drum clean and odor-free.

By combining these simple habits with periodic deep cleaning, you can significantly reduce the risk of unpleasant smells in your laundry.

Additional Tips for Extra Freshness

  • Dry Laundry Immediately: Avoid leaving wet clothes in the drum for extended periods. This can encourage bacterial growth and lead to musty smells.

  • Use Soft, Natural Cleaning Products: Citric acid and vinegar are ideal because they are gentle on both clothes and the machine while being environmentally responsible.

  • Wipe the Drum: Occasionally, wipe down the inside of the drum and door seal with a damp cloth to remove residual moisture.

Conclusion

Musty laundry odors are a common annoyance, but they are easily preventable and solvable with the right approach. Using citric acid or white vinegar in a maintenance wash is a simple, eco-friendly method to neutralize smells and keep your washing machine in top condition.

Regular maintenance, combined with occasional deep cleaning using natural ingredients, ensures that your clothes come out smelling fresh every time. Not only will this improve the quality of your laundry, but it will also extend the life of your washing machine and protect the environment from harsh chemicals.

With this simple hack, musty laundry is a thing of the past. By incorporating citric acid or vinegar into your cleaning routine, you’ll enjoy fresh, clean-smelling clothes without extra expense or effort.
