How to Fix a Stinky Washing Machine: A Step-by-Step Guide
A smelly washing machine can turn laundry day into a dreaded chore. If you’ve ever noticed an unpleasant odor coming from your machine—even after running a cycle—you’re not alone. The good news? With a little know-how and some routine care, you can eliminate the stink and keep your washing machine smelling fresh.
Below, you’ll find everything you need to tackle washing machine odors, including causes, cleaning methods, practical tips, and easy maintenance ideas—broken down in simple steps for stress-free results.
Why Does My Washing Machine Smell?
Before diving into solutions, it helps to understand what’s causing the unpleasant scent:
- Soap Scum Buildup: Over time, leftover detergent and fabric softener residue can cling to the drum, hoses, and other components. This gunk traps dirt and fosters foul odors.
- Mold and Mildew Growth: Warm, damp environments are prime real estate for mold and mildew—especially on door seals and in detergent drawers.
- Trapped Debris: Forgotten socks, hair, pet fur, or lint can accumulate under the drum or in the filter, gradually producing a musty or sour odor.
- Clogged or Slow Drains: Drainage issues can cause dirty water to pool inside the machine, leading to an unpleasant sewage-like smell.
- Washing at Low Temperatures: Frequent cold cycles don’t kill bacteria or flush away buildup, allowing odors to multiply.
Step-by-Step: How to Eliminate Washing Machine Odors
Ready to banish the stink? Here’s how to thoroughly clean and freshen your washing machine.
1. Clean Out the Gasket and Door Seals
Front-loading washers, in particular, have rubber gaskets around the door that easily collect grime and trap moisture.
- Open the door wide.
- Wipe the gasket thoroughly with a damp cloth.
- Use an old toothbrush to gently scrub inside folds where mildew can hide.
- For stubborn mold or mildew, apply a mixture of water and a splash of bleach, vinegar, or a mild cleaning detergent. Wipe clean.
- Dry the area with a microfiber cloth.
2. Wash the Detergent and Fabric Softener Drawers
Soap drawers can easily become coated in sticky residue.
- Fully remove the drawer compartment if possible.
- Soak in warm, soapy water for 10-15 minutes.
- Scrub all compartments using a brush or sponge to remove buildup.
- Rinse well and let dry before reinserting.
3. Clean the Washing Machine Drum
Give the drum a deep clean to eliminate hidden bacteria:
- Check your machine’s manual for any specific cleaning instructions.
-
Run an empty hot water cycle, using:
-
2 cups of white vinegar (poured directly into the drum) for natural cleaning power and odor removal.
or
-
1/2 cup of bleach (added to the detergent compartment) for disinfecting persistent mold or mildew.
-
Once the cycle completes, run another rinse cycle with just hot water to flush out any remaining cleaner.
4. Scrub Around Dispensers and Filters
Don’t forget smaller parts:
- Use a toothbrush or sponge to clean around all dispensers and nooks.
- Locate your washer’s filter (often found near the machine’s base).
- Unscrew or pop open the filter and carefully remove and rinse it under running water.
- Remove any debris or lint and wipe the inside of the filter housing.
5. Freshen and Deodorize
To finish, you can add simple ingredients to combat lingering scents:
- Sprinkle 1/2 cup of baking soda inside the empty drum, then run a short, hot cycle.
- This not only deodorizes but also helps scrub away minor residue.
Ongoing Maintenance: Keep Your Washing Machine Smelling Fresh
A single deep clean is a great start, but regular care keeps odors from returning.
Best Practices for Preventing Future Odors
- Leave the Door Open: Allowing air to circulate helps the drum and gasket dry out, preventing mold.
- Remove Wet Laundry Promptly: Don’t let damp clothes sit after a cycle—they encourage mildew.
- Use Right Amount of Detergent: Too much soap creates excess suds that stick to surfaces and encourage gunk.
- Run Regular Hot Washes: Once every week or two, run a hot wash with no laundry to flush away grime.
- Wipe Down the Gasket and Drawers: After each use, quickly dry the gasket and leave dispensers open to air out.
Quick Monthly Cleaning Routine
- Wipe down gaskets, door, and dispensers.
- Check and rinse the drain filter.
- Run a maintenance wash (hot cycle with vinegar or baking soda).
Troubleshooting Persistent Odors
If smells linger after cleaning:
- Inspect for clogs or slow drainage—clean out hoses if necessary.
- Check for hidden mold in hard-to-reach spots or under the drum.
- If you detect a rotten egg or “sewage” smell, consult a plumber—there might be a plumbing issue rather than an appliance problem.
Practical Tips and Extra Advice
- Avoid Excess Fabric Softener: Fabric softeners easily leave residue that traps odors.
- Try Washing Machine Cleaning Tablets: These are designed to dissolve buildup and are safe for most front and top loaders.
- Clean Laundry Loads: Shake out debris before washing, and avoid overloading the machine.
- Use High-Quality Detergent made for washing machines, especially if you have a high-efficiency (HE) unit.
- Check User Manual: Some machines have special instructions or self-cleaning cycles—take advantage of these features.
Common Challenges (and Solutions)
- Can’t Remove Detergent Drawer? Try soaking it in place with a spray bottle of hot soapy water, then scrub gently.
- Bad Smell Persists After Cleaning? Double-check for trapped items in filter, hose, or under the gasket.
- Sensitive Materials: If using strong cleaners like bleach, ensure the room is well ventilated and follow dilution guidelines to protect rubber seals.
Conclusion
A fresh-smelling washing machine not only makes laundry day more pleasant but also keeps your appliance running better for longer. Odors may be stubborn, but regular cleaning and a few preventive steps make a big difference. Think of it like caring for a car—routine tune-ups lead to smooth, trouble-free operation.
If you follow these steps and build simple maintenance habits into your routine, you’ll say goodbye to stinky wash days for good!
Frequently Asked Questions (FAQs)
Why does my washing machine smell even though I use detergent?
Odors often result from residue left behind by excess detergent and fabric softener, especially if you use too much or wash mostly on cold settings. Bacteria and mold can thrive in this residue, causing bad smells.

A deep clean is recommended once a month or every 30 washes. Wiping down gaskets and leaving the door open after every use also helps prevent odors.
Is vinegar safe to use in my washing machine?
Yes, white vinegar is safe for most machines and is excellent for breaking down grime and neutralizing odors. However, always check your user manual for any manufacturer-specific warnings.
What if my washing machine smells like rotten eggs or sewage?
This may indicate a plumbing issue, often related to a clogged drain or vent. After cleaning the machine thoroughly, if the smell persists, it’s a good idea to contact a plumber.
Can I use store-bought washing machine cleaners instead of DIY solutions?
Absolutely! Washing machine cleaning tablets and commercial solutions are designed to break down buildup and are easy to use. Just follow the instructions on the package for best results.
Taking a bit of time for washing machine care will keep things fresh and functional, ensuring your clean laundry always smells just the way it should!
