How to Clean a Smelly Washing Machine
A washing machine is supposed to leave your clothes fresh and clean, so a musty or unpleasant smell coming from the machine can be surprisingly frustrating. In many cases, however, a smelly washer simply needs a thorough cleaning.

Over time, detergent residues, fabric softener, dirt, limescale and moisture can collect in places that are easy to overlook. Modern washing machines also frequently run at lower temperatures, which can make regular maintenance particularly important.
Why Does My Washing Machine Smell?
A washing machine contains several areas where moisture and residues can remain after a cycle. If these areas stay damp, deposits can gradually build up and produce an unpleasant smell.
Common sources of washing machine odors include:
- The rubber door seal: Moisture, lint, hair and small amounts of detergent or dirt can collect in the folds of the seal.
- The detergent drawer: Detergent and fabric softener residues can build up inside the drawer and the compartments around it.
- The drum and interior: Dirt, detergent residues and limescale can accumulate inside the machine, including areas that are difficult to reach by hand.
- The drain filter: Depending on the model, lint, hair and small debris can collect in the filter.
- Residual moisture: Closing the door immediately after a wash can leave the inside of the machine damp for an extended period.
The important point is that the visible parts of the machine are not necessarily the only parts that need attention. A proper cleaning routine should address both the areas you can reach by hand and the interior of the appliance.
How to Clean a Smelly Washing Machine
Before cleaning, make sure the washing machine is empty. Always follow your appliance manufacturer’s instructions, especially before opening or cleaning the drain filter.
Step 1: Empty the Washing Machine
Remove all laundry from the drum. An empty machine allows a dedicated cleaning cycle to work throughout the appliance without laundry, regular detergent or fabric softener getting in the way.
Step 2: Clean the Rubber Door Seal
If you have a front-loading washing machine, inspect the rubber seal around the door. Gently pull back the folds and remove visible lint, hair or other debris.
Wipe the seal thoroughly with a suitable cleaning cloth and dry the area afterward. Pay particular attention to the lower part of the seal, where moisture and debris can remain after a wash.
If the seal is damaged or has persistent staining that does not improve with normal cleaning, the appliance may need professional attention or a replacement seal.
Step 3: Clean the Detergent Drawer
Remove the detergent drawer if your washing machine allows it. Rinse away detergent and fabric softener residues and clean the compartments thoroughly.
Do not forget the area inside the machine where the drawer sits. Residue can accumulate there even when the drawer itself looks clean.
Step 4: Check the Drain Filter
Many washing machines have a drain or lint filter that collects small objects and debris. Its location and cleaning procedure vary from one model to another, so check your owner’s manual before opening it.
If the filter is accessible, clean it according to the manufacturer’s instructions. Keep a towel or suitable container nearby because some water may escape when the filter is opened.
Step 5: Run a Washing Machine Cleaning Cycle
Once the accessible parts of the machine have been cleaned, a dedicated washing-machine cleaner can help remove deposits and residues from inside the appliance.
This is particularly useful when the machine has developed a persistent odor or has not been thoroughly cleaned for some time.
Dr. Beckmann Washing Machine Hygiene Cleaner
Dr. Beckmann Washing Machine Hygiene Cleaner is specifically designed to clean the inside of washing machines.
According to the manufacturer, dirt and detergent residues can accumulate inside a washing machine and contribute to unpleasant odors, particularly when the machine is frequently used at low temperatures. The cleaner is designed to dissolve deposits in areas that are difficult to reach, including parts around the drum, detergent drawer, heating element, pump and drain. The manufacturer states that the product eliminates 99.9% of bacteria and fungi during the cleaning cycle.
For the manufacturer’s recommended cleaning procedure, the machine should be empty and the complete 250 g (8.8 oz) package is placed directly into the drum. The recommended main wash temperature is at least 140 °F (60 °C). Always check the current product instructions and your washing machine manufacturer’s instructions before use.
Cleaning a Washing Machine Between Deep Cleanings
Your washing machine does not have to wait until it smells bad before it gets some attention. Simple maintenance between more thorough cleaning cycles can help keep moisture and residue under control.
After a wash, leave the door open when practical so the inside of the machine can dry. If your machine has a removable or pull-out detergent drawer, leaving it slightly open can also help the area dry.
Wipe away visible moisture around the door seal and clean the detergent drawer whenever you notice residue beginning to accumulate.
These small habits take very little time and can make a noticeable difference over the long term.
Dr. Beckmann Washing Machine Freshness Cleaner Caps
For routine cleaning between more thorough maintenance cycles, Dr. Beckmann Washing Machine Freshness Cleaner Caps offer a convenient option for keeping the washing machine fresh.
The caps are designed for a shorter cleaning cycle and can be used between more intensive cleaning treatments. According to the product instructions, they are used in an empty washing machine without laundry or regular detergent.
The manufacturer’s instructions specify use from 86 °F (30 °C). Always check the current package instructions for the correct cycle and temperature before use.
How to Prevent Bad Washing Machine Odors
Once you have cleaned a smelly washing machine, a few simple habits can help prevent the problem from returning.
Let the Machine Dry
When practical, do not close the washing machine door immediately after every cycle. Leaving it open allows residual moisture to evaporate and helps the interior dry.
Keep the Detergent Drawer Clean
Detergent and fabric softener residues can build up over time. A quick rinse and wipe of the drawer can prevent a small amount of residue from becoming a larger cleaning job.
Use the Correct Amount of Detergent
Using more detergent does not necessarily make laundry cleaner. Follow the dosing instructions on your detergent and take factors such as water hardness, load size and the level of soiling into account.
Excess detergent can leave additional residue behind, which is one more reason to avoid simply adding more product when a load is heavily soiled.
Do Not Leave Wet Laundry Sitting in the Machine
Remove finished laundry reasonably soon after the cycle ends. Wet clothes left in a closed washing machine for a long time can develop an unpleasant smell of their own and contribute to the impression that the machine itself is dirty.
Do Not Rely Exclusively on Low-Temperature Washing
Lower temperatures are appropriate for many everyday laundry loads and can help reduce energy use. However, regular machine maintenance remains important, particularly when a washing machine is used frequently at lower temperatures.
The goal is not to wash every load at a high temperature. Instead, use the temperature appropriate for the laundry and give the washing machine itself regular attention.
Should You Use Vinegar or Baking Soda to Clean a Washing Machine?
Vinegar and baking soda are frequently mentioned as homemade solutions for washing machine odors. They are not necessary for routine washing-machine maintenance, and they should not automatically be treated as substitutes for a cleaner specifically formulated for the appliance.
A dedicated washing-machine cleaner has the advantage of being developed for this particular cleaning task and comes with specific instructions for use. If you prefer a household cleaning method, follow the recommendations for your particular washing machine rather than experimenting with different cleaning substances.
Most importantly, never mix different cleaning products unless the manufacturer specifically says that they can be combined. Never mix acidic cleaners with chlorine-based products.
How Often Should You Clean a Washing Machine?
There is no single cleaning schedule that fits every household. A machine used frequently for heavily soiled laundry may need attention more often than one used for a smaller amount of lightly soiled laundry.
A practical approach is to inspect the door seal and detergent drawer regularly, clean accessible areas whenever residue becomes visible, and perform a thorough machine-cleaning cycle when odors or buildup begin to appear.
If your washing machine is used frequently at low temperatures, regular maintenance is especially worthwhile because residues can accumulate over time.
When a Washing Machine Smell Needs Professional Attention
Cleaning can solve many ordinary odor problems, but not every smell comes from detergent residue or normal buildup.
Consider consulting the appliance manufacturer, a qualified technician or a professional repair service if:
- the smell remains after a thorough cleaning,
- the machine repeatedly develops a strong odor shortly after cleaning,
- there is standing water that does not drain properly,
- the machine leaks,
- you notice unusual noises or error messages,
- the door seal is damaged, or
- you suspect a problem with the drain, pump or another internal component.
A persistent odor combined with a drainage or mechanical problem may indicate an issue that cleaning alone cannot fix.
Frequently Asked Questions
Why does my washing machine smell even though I clean it regularly?
Odors can come from areas that are easy to overlook, including the folds of the door seal, the detergent drawer, the drain filter and internal components. A thorough cleaning of the machine may be necessary rather than simply wiping the visible surfaces.
Can I clean my washing machine with vinegar?
Vinegar is often suggested as a household cleaning method, but it is not necessary for routine washing-machine maintenance. Follow your appliance manufacturer’s recommendations and never mix vinegar or other acidic cleaners with chlorine-based products.
Can baking soda remove washing-machine odors?
Baking soda is commonly promoted as a home remedy for odors, but a dedicated washing-machine cleaner is a more targeted option when the machine itself needs a thorough cleaning. Always follow your appliance manufacturer’s recommendations.
Should I leave my washing machine door open?
Yes, when practical. Leaving the door open after a wash allows residual moisture inside the machine to evaporate and helps the interior dry between loads.
How do I clean the rubber seal on a front-loading washing machine?
Pull back the folds of the seal and remove visible lint, hair and debris. Wipe the area thoroughly and dry it afterward. If the seal is damaged or heavily stained and the problem keeps returning, it may need professional inspection or replacement.
Why does my laundry smell bad after washing?
If freshly washed laundry smells unpleasant, the washing machine itself may have accumulated dirt, detergent residues or other deposits. Leaving wet laundry in the machine for too long can also contribute to bad odors.
Final Thoughts
A smelly washing machine usually needs attention in the places where moisture, dirt and detergent residues can accumulate. Cleaning the door seal, detergent drawer and filter, followed by an appropriate machine-cleaning cycle, provides a sensible starting point.
The most effective long-term approach is regular maintenance rather than waiting until the smell becomes noticeable. Let the machine dry between loads, use detergent according to the manufacturer’s recommendations and give the appliance a thorough cleaning when residue or odors begin to appear.
