Ever opened your washing machine and noticed a musty smell coming from inside?
It is a common laundry-room problem, especially in busy homes where the washer runs often and the door closes right after each cycle. Even though the machine is designed to clean clothes, moisture, detergent residue, lint, and everyday laundry buildup can collect in small areas over time.
The good news: a smelly washing machine does not always mean something is wrong with the appliance. In many cases, a few simple cleaning habits can help the washer feel fresher and easier to keep up with.
This guide explains what causes washing machine odors, how to clean the key areas, and how to build a simple routine that fits into everyday home care.
Quick Answer: How Do You Remove Bad Smells From a Washing Machine?
To remove bad smells from a washing machine, start by cleaning the areas where moisture and residue often sit: the rubber gasket, detergent drawer, drum, and filter if your model has one. Then run an empty hot water or clean-washer cycle with a washing machine cleaner tablet. After the cycle, wipe the inside of the washer and leave the door and detergent drawer open to dry.
For many households, a monthly washer care routine can help reduce the chance of musty smells returning.
Why Does a Washing Machine Smell Bad?
A washing machine can smell bad when moisture and residue sit inside the appliance after each cycle. The odor may come from one area or a combination of several small buildup points.
Common causes include:
-
Moisture trapped in the rubber door gasket
-
Detergent or fabric softener residue
-
Laundry left inside too long
-
Too much detergent
-
Low-temperature wash cycles used often
-
Lint, hair, or debris in small creases
-
A dirty detergent drawer
-
A clogged or neglected pump filter on some front-load models
-
Keeping the washer door closed between cycles
When these areas stay damp, the washer may start to smell musty or stale, even if the drum looks clean at first glance.
Common Places Where Washer Odor Hides
Before trying to freshen the whole machine, it helps to know where the smell may be coming from.
Rubber door gasket
Front-load washers often have a rubber gasket around the door. This seal helps prevent leaks, but the folds can hold moisture, lint, hair, and detergent residue.
Detergent drawer
The detergent drawer can collect leftover detergent, softener, and water. If it stays damp, it may start to smell stale.
Washer drum
The drum may hold residue from detergent, fabric softener, dirt, and laundry soils. An empty cleaning cycle can help refresh this area.
Pump filter
Some front-load washers have a pump filter near the lower front of the machine. If your model has one, it may collect lint, small debris, and water.
Closed door after washing
Closing the washer door immediately after a cycle can trap moisture inside. That damp air can make the washer smell less fresh between laundry days.
How To Remove Bad Smells From a Washing Machine
Here is a simple step-by-step routine you can use at home. Always check your washer’s care instructions first, especially before cleaning the filter or using any cleaner.
Step 1: Empty the Washer
Start with an empty washer. Remove all laundry from the drum, including small items like socks or washcloths that may be stuck near the back.
Do a quick check for:
-
Loose lint
-
Hair
-
Coins
-
Small fabric pieces
-
Pet hair
-
Tissue pieces
-
Items trapped in the gasket
A cleaning cycle should be run with no clothes inside.
Step 2: Clean the Rubber Gasket
Open the washer door and gently pull back the rubber gasket. Use a soft cloth to wipe inside the folds.
Focus on areas where you see:
-
Water sitting in the seal
-
Gray residue
-
Lint or hair
-
Detergent buildup
-
Small trapped items
For tighter spots, use a small soft brush. Avoid sharp tools that could damage the rubber.
This step is especially helpful for front-load washers, where the gasket is one of the most common odor-holding areas.
Step 3: Clean the Detergent Drawer
Pull out the detergent drawer according to your washer’s instructions. If the drawer has removable inserts, take them out and rinse them with warm water.
Use a small soft brush to clean:
-
Detergent compartments
-
Softener compartment
-
Drawer corners
-
The drawer opening inside the washer
Dry the drawer parts before putting them back. If your washer has an auto-dispenser, check your manual before removing or rinsing any parts.
A simple between-wash habit: leave the drawer slightly open after laundry so it can air dry.
Step 4: Add a Washing Machine Cleaner Tablet
Once the visible areas are wiped, use a washing machine cleaner tablet to help refresh the drum and support routine maintenance.
Place one tablet directly into the empty washer drum. Do not put it in the detergent drawer unless the product label specifically says to do so.
A pre-measured tablet helps keep the process simple: no measuring, no pouring, and no bulky bottle sitting in the laundry room.
Step 5: Run a Hot Water or Clean-Washer Cycle
Choose your washer’s clean-washer cycle, tub clean cycle, or a hot water cycle based on your machine’s instructions.
General steps:
-
Make sure the washer is empty.
-
Place the tablet in the drum.
-
Select a clean-washer, tub clean, or hot water cycle.
-
Run the full cycle.
-
Let the cycle finish before opening the door.
Cycle options can vary by washer model, so follow your machine’s care guide when choosing the setting.
Step 6: Wipe and Air Dry
When the cycle is complete, open the door and wipe the inside of the washer with a clean cloth.
Focus on:
-
Door glass
-
Rubber gasket
-
Drum opening
-
Any loosened residue
-
Areas where water is still sitting
Then leave the washer door open for a while so the inside can dry. If possible, leave the detergent drawer slightly open too.
Air drying is a small habit, but it can make a big difference in helping the washer feel fresher between cleaning cycles.
What About Baking Soda or Vinegar?
Some people use household options like baking soda or vinegar to freshen a washer. These methods may be helpful for light odor, but they are not always the easiest or most consistent routine for every home.
If you use household cleaning methods, keep these points in mind:
-
Always check your washer manual first.
-
Do not mix vinegar, bleach, tablets, or other cleaning products.
-
Use one cleaning method at a time.
-
Avoid using anything that your washer manufacturer does not recommend.
-
Rinse and wipe the washer afterward.
For a simpler routine, a washing machine cleaner tablet is often easier to remember and easier to use consistently.
How To Prevent Bad Smells From Coming Back
Removing washer odor is helpful, but preventing it from returning is even better. These small habits can make daily laundry feel easier.
Leave the door open after washing
After you remove laundry, leave the door open so moisture can escape.
Let the detergent drawer dry
Pull the drawer open slightly between loads. This gives trapped moisture a chance to evaporate.
Use the right amount of detergent
Too much detergent can leave residue behind. Follow detergent instructions and use the correct amount for your load size and washer type.
Remove laundry promptly
Wet laundry left in the drum can create a stale smell. Move clothes to the dryer or drying rack as soon as you can.
Wipe the gasket regularly
A quick wipe after laundry can help reduce moisture in the folds of the rubber seal.
Run a monthly washer care cycle
A monthly routine is easier to remember than waiting until the washer smells again.
How Often Should You Clean a Smelly Washing Machine?
For many households, cleaning the washer once a month is a simple starting point.
You may want to clean it more often if:
-
You do laundry almost every day
-
You wash towels frequently
-
You wash pet bedding
-
You wash sportswear or gym clothes often
-
You use fabric softener regularly
-
You mostly wash with cold water
-
Your laundry room is humid
-
You notice odor coming back quickly
For a lighter-use household, you may be able to clean less often. The best routine is one you can remember and repeat.

Common Mistakes To Avoid
Mistake 1: Only cleaning the drum
The drum matters, but odor often hides in the gasket, drawer, and filter area too.
Mistake 2: Using more detergent to cover the smell
More detergent can create more residue. Use the right amount instead.
Mistake 3: Closing the washer right after a cycle
A closed door traps moisture. Leave the door open when possible.
Mistake 4: Forgetting the detergent drawer
The drawer can hold water and residue even when the drum looks clean.
Mistake 5: Mixing cleaning products
Do not mix vinegar, bleach, tablets, or other cleaning products. Use one method at a time.
Mistake 6: Waiting until the smell gets strong
A simple monthly routine is easier than dealing with a stronger musty odor later.
Key Takeaways
A smelly washing machine is usually caused by moisture, detergent residue, lint, or buildup sitting in hidden areas of the washer.
To remove bad smells, clean the gasket, detergent drawer, drum, and filter if your model has one. Then run an empty hot water or clean-washer cycle with a washing machine cleaner tablet. After the cycle, wipe the washer and leave the door open to dry.
The easiest way to keep up with washer care is to turn it into a simple routine. One tablet, one empty cycle, and a few small drying habits can help make washer care feel easier to keep up with.
