Introduction
Learning how to clean a washing machine is essential when you notice musty smells or residue inside the drum. Even though washers clean clothes, detergent buildup, lint, body oils, and trapped moisture can slowly collect in hidden areas. As a result, that buildup reduces cleaning performance and creates conditions where odor and mold develop over time.
Based on manufacturer maintenance guidance and appliance care best practices, routine washer cleaning should be part of regular home upkeep. Removing residue and excess moisture restores cleaning performance and helps prevent odor from returning—so both the machine and your laundry stay fresher longer.
Quick Answer: How Do You Clean a Washing Machine?
Run an empty hot cycle using a washer cleaner tablet (recommended for routine maintenance) or white vinegar for occasional descaling. Then wipe the rubber seal, clean the detergent drawer, and clear the drain filter. Finally, dry the machine completely to prevent trapped moisture and odor from returning.
Why Washing Machines Get Dirty
Even though washers clean clothes, residues remain inside the machine.
Common buildup sources include:
- Detergent and fabric softener residue
- Lint and dirt particles
- Body oils and sweat
- Moisture trapped after washing
In high-efficiency washers, low-water cycles increase the risk of residue accumulation if detergent is overdosed or rinse cycles are insufficient.
Signs Your Washer Needs Cleaning
You may need to clean your washer if you notice:
- Musty smell inside drum
- Black spots on rubber seal
- Clothes smell after washing
- Slow draining water
- Sticky detergent drawer
If your clothes smell even after washing, see our guide on when washer buildup transfers odor back into clothes to identify whether the issue is washer buildup or fabric-related.
What You Need Before You Start
- White vinegar or bleach
- Microfiber cloth or sponge
- Old toothbrush
- Hot water
How to Clean a Washing Machine Step by Step
Phase 1: Run a Drum Cleaning Cycle
Set the washer to the hottest, longest empty cycle (or Tub Clean/Self Clean if available).
Use a washer cleaner tablet for routine cleaning or white vinegar occasionally for light mineral buildup.
Phase 2: Clean High-Risk Components
After the cycle finishes, clean the following areas:
- Rubber door seal (front-load)
- Detergent drawer and internal channels
- Drain filter (if accessible)
Phase 3: Dry-Out Protocol
Wipe moisture from the drum and seal.
Leave the washer door and detergent drawer open for airflow.
This prevents mold and odor from returning.
How to Clean a Front-Load Washing Machine
Front-load washers require extra attention because moisture collects around the door seal.
Focus on:
- Wiping and drying the rubber seal weekly
- Cleaning the detergent drawer monthly
- Checking the drain filter every 1–3 months
- Running a monthly Tub Clean cycle
For odor-specific troubleshooting, see our full front-load washer odor guide.
How to Clean a Top-Load Washing Machine
Top-load washers retain less moisture but can collect detergent residue.
Focus on:
- Running a hot drum cleaning cycle every 2–3 months
- Cleaning detergent buildup from the rim and lid
- Inspecting filters if your model includes one
Clean the Rubber Door Seal
- Pull seal back gently.
- Wipe inside using vinegar or mild bleach solution.
- Scrub mold spots.
- Dry completely.

Clean the Detergent Drawer
- Begin by removing the drawer.
- Rinse it under hot water.
- Next, scrub the corners and channels.
- Finally, dry it completely before reinstalling.
Clean the Drain Filter
- Locate filter using manual.
- Place towel below.
- Remove debris.
- Rinse and reinstall.
Dirty filters cause odor and drainage issues.
Clean Drain Hose and Drain Pipe
If you notice slow drainage or odor near the outlet pipe, inspect the drain hose for buildup. Detailed hose maintenance steps are covered in our dedicated drain-hose maintenance steps (for odor + backups).
Washing Machine Still Smells After Cleaning?
Possible causes:
- Dirty drain filter
- Blocked hose
- Excess detergent residue
- Sewer drain odor
- Incomplete drying after washes
Run another hot cycle and recheck hidden areas.
Can You Use Vinegar to Clean a Washing Machine?
Yes, white vinegar can help dissolve light mineral deposits and mild odor buildup when used occasionally. However, for regular monthly maintenance, washer cleaner tablets are generally safer and more consistent.
Avoid frequent vinegar use on rubber components, and never mix vinegar with bleach.
How Often Should You Clean a Washing Machine?
- Monthly for regular use
- Every two weeks for heavy laundry
- Immediately if odor appears
Does This Work for All Washing Machine Brands?
Yes, including Samsung, LG, Whirlpool, GE, and Haier.
If your washer has a Self-Clean or Tub Clean cycle, use it monthly with cleaner tablets.
Follow manufacturer instructions when available.
How to Prevent Washing Machine Smells
- Leave the washer door open after use
- Remove clothes promptly
- Use the correct detergent amount
- Avoid excess fabric softener
- Run a monthly cleaning cycle
Simple habits prevent long-term buildup.
Expert Note
High-efficiency washers use lower water volumes, which increases the risk of detergent residue and biofilm formation when detergent is overdosed or rinse cycles are insufficient.
Key Takeaways
- Odors come from residue and moisture buildup.
- Front-load washers need seal cleaning.
- Vinegar helps but should not be overused.
- Filters and drawers often hide odor sources.
- Monthly cleaning prevents mold growth.
Cleaning Methods Compared
| Method | Best For | Safe for Front-Load | Frequency | Important Notes |
|---|---|---|---|---|
| Vinegar | Light odor & minerals | Limited use | Every 2–3 months | Never mix with bleach |
| Bleach | Mold & bacteria | Yes | Every 3–6 months | Ventilate room |
| Cleaner Tablets | Maintenance cleaning | Yes | Monthly | Safest routine option |
| Baking Soda | Mild deodorizing | Yes | Occasionally | Use only with water |
Consistent washing machine cleaning works best when each component is maintained on a schedule.
Cleaning Frequency by Washer Part
| Washer Part | Frequency | Reason |
|---|---|---|
| Drum | Monthly | Prevent buildup |
| Door Seal | Weekly wipe | Stop mold growth |
| Drawer | Monthly | Prevent residue |
| Filter | Every 1–3 months | Improve drainage |
| Drain Hose | Every 6–12 months | Avoid blockage |
Front-Load vs Top-Load Cleaning Needs
| Feature | Front-Load Washer | Top-Load Washer |
|---|---|---|
| Common issue | Seal mold | Detergent buildup |
| Seal cleaning needed | Yes | No |
| Filter cleaning | Often | Model dependent |
| Cleaning frequency | Monthly | Every 2–3 months |
| Main odor cause | Moisture | Soap residue |
Conclusion
Knowing how to clean a washing machine prevents odor, detergent residue buildup, and long-term performance issues. Most washer problems are caused by moisture retention and overdosed detergent rather than mechanical failure. Cleaning the drum, seal, drawer, and filter on a consistent schedule keeps both your machine and laundry fresh while extending appliance lifespan.

FAQs
Clean your washing machine at least once a month if you use it regularly, more often if you wash heavily soiled clothes or notice odors.
Persistent odors often come from hidden buildup in the drain filter, hoses, or gasket, so clean these parts and run an extra hot rinse.
The best deep clean is running a hot empty cycle with a commercial washer cleaner tablet or white vinegar, followed by scrubbing seals and dispensers.
Although baking soda and vinegar can help deodorize a machine, they neutralize each other when mixed, so add them separately during different parts of the cleaning process.
