Musty Smell After Laundry? How to Deep Clean Your Washing Machine in 30 Minutes

If your clothes come out of the washer smelling worse than before, you’re not alone. That unpleasant musty odor isn’t caused by your laundry detergent—it’s a sign your washing machine needs a serious clean. Even though your washer handles soapy water daily, over time detergent residue, lint, and moisture build up in hidden areas, creating the perfect home for mold and bacteria. The good news? You can deep clean your washing machine in just 30 minutes and bring back that fresh-laundry scent you love.

Step 1: Wipe the Drum and Gasket

Start by removing any clothes or items inside the washer. Mix equal parts water and white vinegar in a spray bottle, and generously spray the inside of the drum. Pay special attention to the rubber gasket around the door—it often traps lint, hair, and moisture that cause that musty smell. Wipe thoroughly with a microfiber cloth or sponge. If you spot mold or black residue, use a small brush or an old toothbrush to scrub the area gently.

Step 2: Run a Hot Cycle with Vinegar

Next, pour two cups of white vinegar directly into the drum. Run the washer on the hottest, longest setting. Vinegar naturally breaks down soap scum and kills odor-causing bacteria. You don’t need to add detergent—just vinegar. This step alone removes most of the buildup and neutralizes any lingering smells.

Step 3: Add Baking Soda for Extra Freshness

Once the first cycle finishes, sprinkle half a cup of baking soda into the drum and run another short hot cycle. Baking soda is a gentle cleaner that helps eliminate any remaining grime and deodorizes your machine. When it’s done, open the washer door and let it air dry for at least an hour to prevent new odors from forming.

Step 4: Clean the Detergent Drawer and Filter

Pull out the detergent dispenser and rinse it under warm water. If you see mold or residue, soak it in a mix of vinegar and water for 10–15 minutes. Wipe the inside of the slot before putting it back. Don’t forget about the filter—usually located at the bottom front of the machine. Remove it carefully (place a towel underneath) and clean out lint, coins, or debris. A clogged filter can also cause unpleasant smells.

Step 5: Keep It Clean Long-Term

To keep your washing machine smelling fresh, leave the door slightly open after every load to let it dry. Once a month, repeat this deep clean. If you live in a humid area, consider wiping the gasket after each use. These simple habits prevent mold growth and extend your washer’s lifespan.
