How to Get Rid of That Musty Smell in Your Washing Machine

A musty smell coming from your washing machine is not only unpleasant but also a sign that bacteria, mold, or mildew may be growing inside. This common issue can leave your clothes smelling less than fresh, even after a wash. Fortunately, getting rid of that musty odor is simpler than you might think. With just a few easy steps, you can restore your washing machine to its fresh and clean state.

In this article, we’ll walk you through six effective methods to get rid of the musty smell in your washing machine. By following these tips, you can ensure that your laundry comes out smelling fresh every time, without any unpleasant odors.

1. Clean the Rubber Gasket

The rubber gasket around the door of your washing machine is a common culprit for musty smells. It’s prone to trapping moisture, soap scum, and grime, which can lead to the growth of mold and mildew. To clean it, simply wipe the gasket down with a damp cloth and a small amount of detergent. For stubborn mold, you can use a mixture of water and vinegar or a mild bleach solution. Make sure to dry the gasket thoroughly after cleaning to prevent moisture buildup.

To keep the gasket clean in the future, leave the door slightly ajar between washes to allow air to circulate and prevent the growth of mold.

2. Run a Hot Water Cycle with Vinegar

Running a hot water cycle with vinegar is one of the most effective ways to eliminate musty odors. Vinegar is a natural deodorizer and disinfectant, which helps break down mold, mildew, and soap residue inside the machine. Simply pour two cups of white vinegar into the drum and run the machine on the hottest setting without any clothes inside. This will help disinfect the interior and neutralize the odors.

For extra freshness, you can follow up with a second hot water cycle, this time adding half a cup of baking soda directly into the drum. The combination of vinegar and baking soda can help leave your washing machine smelling fresh and clean.

3. Leave the Door Open After Use

One of the easiest ways to prevent musty odors from building up in your washing machine is to leave the door open after each use. This allows the interior to air dry properly, preventing moisture from getting trapped in the drum or gasket. If you close the door immediately after washing, the humid environment becomes a breeding ground for mold and mildew.

By simply leaving the door ajar for a few hours after each load, you’ll reduce the likelihood of that musty smell returning and keep your machine smelling fresh.

4. Clean the Detergent Drawer

The detergent drawer in your washing machine can easily accumulate soap scum, fabric softener residue, and water. This buildup can contribute to musty smells over time. To clean the drawer, remove it from the machine (if possible) and soak it in warm, soapy water. Use an old toothbrush to scrub away any residue, paying special attention to corners and hard-to-reach spots.

Once cleaned, dry the drawer thoroughly before reinserting it into the machine. Regularly cleaning this part of your washing machine can help prevent the accumulation of residues that contribute to odors.

5. Use a Washing Machine Cleaner

There are many washing machine cleaning products available that are designed specifically to eliminate musty smells and clean the interior of the machine. These cleaners are formulated to dissolve soap scum, mold, and mineral deposits that can cause odors. Simply follow the instructions on the product label, usually adding the cleaner to the drum or detergent drawer and running a hot water cycle.

While not necessary for every wash, using a washing machine cleaner once a month can help keep your machine smelling fresh and functioning efficiently.

6. Check the Drain Pump Filter

Sometimes, the musty smell can be traced to a clogged drain pump filter. This filter collects debris and lint from your laundry, and if it becomes clogged, it can cause water to stagnate, leading to unpleasant odors. Consult your washing machine’s manual to locate the drain pump filter, then remove any lint, debris, or buildup. Clean the filter regularly to ensure proper drainage and reduce the chance of odors.

Additionally, checking the filter can help your machine run more efficiently, as a clogged filter can also impact performance.
