Ultimate Guide: How to Clean a Smelly Washer

If your washing machine smells more like mildew than clean laundry, you’re not imagining that stagnant water smell. Washers can get funky fast, especially if they aren’t cleaned regularly. But don’t stress—there are simple ways to eliminate the smell and keep it from coming back. Let's walk through everything you need to know to get your washer back to smelling fresh.

Why Does My Washer Smell?

Even the best washers need TLC. Here’s why your machine might stink:

• Detergent Overload: Too much detergent? It leaves behind a residue that traps moisture—hello, bacteria.

• Fabric Softener Build-Up: Softener smells good in theory, but it creates a waxy coating that invites mold.

• Moisture Traps: Front-load washers are famous for holding onto water in door seals and gaskets.

• Skipped Cleanings: Grease builds up quickly if you don’t clean the drum, gasket, and detergent drawer.

Let’s fix it!

How to Clean a Washing Machine

Step 1: Clean the Drum

1. Remove everything from the drum. No laundry should be left inside.

2. Pour two cups of white vinegar straight into the drum.

3. Run a hot cycle to flush out bacteria and break down odors.

4. Wipe the inside of the drum with a microfiber cloth to catch any lingering grime.

Step 2: Clean the Agitator (If Applicable)

1. If your washing machine has a detachable agitator, carefully remove it.

2. Soak the agitator in warm, soapy water to loosen dirt and detergent build-up.

3. Use an old toothbrush to scrub away any residue stuck in small crevices.

4. Rinse and dry the agitator before placing it back in the machine.

Step 3: Tackle the Gasket and Door

1. Inspect the gasket (the rubber seal around the door) for trapped lint, mildew, or grime.

2. Mix equal parts vinegar and water in a spray bottle.

3. Spray the gasket and scrub gently with a sponge or soft brush to loosen any build-up.

4. Wipe the gasket and door dry with a clean towel to prevent moisture from sitting there.

Step 4: Deep Clean the Detergent Drawer

1. If your washer allows, remove the detergent drawer.

2. Soak the drawer in warm, soapy water to soften any residue.

3. Use an old toothbrush to scrub out all the little corners and crevices.

4. Wipe the inside of the compartment where the drawer slides in to remove any hidden grime.

Why Is It Important to Regularly Clean Your Washer?

Regular washer maintenance is essential for performance, hygiene, and longevity. Here’s why it matters:

• Prevents Odors and Mold: Cleaning your washer helps eliminate the build-up of mold, mildew, and bacteria that cause unpleasant smells.

• Improves Wash Quality: A clean washer ensures your clothes come out fresher by preventing detergent and dirt build-up from redepositing on fabrics.

• Extends Washer Lifespan: Routine care protects your washer’s components, reducing wear and tear and saving you money on repairs or early replacements.

• Prevents Allergens: Leftover detergent and mold can trigger allergies. Regular cleaning keeps your laundry environment allergen-free.

• Reduces Maintenance Costs: A well-maintained washer runs more efficiently, meaning fewer breakdowns and better energy usage.

Easy Tips to Keep Your Washer Smelling Great

A little maintenance goes a long way to keep your washer odor-free. Whether you’re dealing with a high-efficiency front-load washer or a traditional top-load washer, following these quick tips can help prevent buildup and mildew from sneaking up on you. Here are some simple, practical steps to keep odors away for good:

• Use the right amount of detergent. Too much soap might seem helpful, but it leaves behind a residue that traps moisture and bacteria. Stick to the recommended dose to prevent buildup.

• Leave the washer door open after every load. This gives the drum a chance to dry out and prevents moisture from sitting inside, which is the perfect breeding ground for mold.

• Wipe the gasket and drum dry once you’re finished. It only takes a few seconds and helps stop mildew from forming in hard-to-reach areas.

• Run a cleaning cycle every month with hot water and vinegar or a store-bought washer cleaner. This routine flushes out detergent residue and grime before it can become a problem.

• Skip fabric softener. It leaves behind a sticky film that encourages mold growth. Instead, try vinegar as a natural alternative to keep clothes soft and your washer free from buildup.

FAQ: What to do About a Smelly Washer

1. Why is my washing coming out smelly?
Smelly laundry is usually caused by detergent buildup, trapped moisture, or mold in your washer. Using too much detergent, skipping routine cleanings, or leaving the washer door closed after a cycle can create the perfect environment for bacteria and odors.

2. Should you put vinegar in the washing machine?
Yes! Adding a cup of vinegar during a hot wash cycle can help break down buildup, soften fabrics, and eliminate odors. It’s also a natural alternative to fabric softener, keeping your machine clean and your clothes smelling fresh.

3. How to sanitize a washing machine?
To sanitize your washer, run a hot cycle with either bleach or vinegar. Add bleach to the detergent dispenser (about 1/2 cup) or pour vinegar directly into the drum. For extra cleaning power, wipe down the gasket and dispenser drawer after the cycle finishes.

4. How do I make my washing smell better?
Use the right amount of detergent (too much can cause odors), keep the door open between loads to prevent moisture build-up, and run a monthly cleaning cycle with vinegar or a washer cleaner. For an added boost, toss in scented dryer sheets or laundry boosters during the drying process.

5. Can you put bleach in a washing machine?
Yes, bleach can be used in your washer to sanitize and remove stains. Use about 1/2 cup in the detergent dispenser and run an empty, hot cycle. Be careful not to overuse bleach, as frequent use may damage rubber seals over time.
