How to Clean a Washing Machine: Why It Smells and How to Keep It Fresh

Quick Answer: To clean a washing machine, run an empty hot cycle with a washer cleaner or the amount of bleach your manual recommends, then scrub the door gasket, detergent drawer and drain filter. Repeat about once a month. Leaving the door open after each load and using less detergent stops most odors from returning.

Your laundry comes out of the washer and somehow smells worse than when it went in. Towels have a sour, musty note, and when you open the machine you catch a whiff of something damp. It feels backwards, but it is one of the most common household complaints. A washing machine cleans your clothes, yet almost nobody cleans the washing machine.

The good news is that most washer odors come from a few predictable causes, and fixing them takes less than an hour. This guide covers why washers smell, how to clean front load and top load machines step by step, and the habits that keep the smell from coming back.

Why Does My Washing Machine Smell?

Short answer: Most washer odors come from a damp film of detergent residue, fabric softener, lint and body soil that builds up inside the machine. Bacteria and mold feed on that film in the dark, moist interior, producing a musty or sour smell that transfers to your laundry.

Here are the usual culprits:

  • Too much detergent. Extra soap does not rinse away fully and leaves a sticky residue.
  • Fabric softener buildup. Liquid softener coats the dispenser, drum and hoses over time.
  • A closed door between loads. Trapped moisture never dries out.
  • Wet clothes left sitting. A load left in the drum for hours can sour quickly, especially in summer.
  • Cold water only washing. Cold cycles save energy but do less to dissolve greasy residue, so occasional hot cycles help.
  • A clogged drain pump filter. Front loaders collect lint, coins and debris in a filter that many owners never open.
  • Damp, humid air. In coastal cities like Norfolk, laundry rooms dry slowly, which gives odors a head start.

Do Front Load or Top Load Washers Smell More?

Short answer: Front load washers are more likely to develop odors because their airtight door seal traps moisture, and the rubber gasket folds hold water, lint and residue. Top load washers smell less often but still build up residue under the agitator, around the rim and in dispensers.

FeatureFront Load WasherTop Load Washer
Odor riskHigherModerate
Main problem areaRubber door gasketUnder the rim and agitator
Drain filter accessUsually a small door at the front bottomOften not user accessible
Water useLower, so residue rinses away lessHigher in traditional models
Best drying habitLeave the door and drawer openLeave the lid open

Neither type is “dirty” by design. Both simply need regular maintenance, just in slightly different places.

What You Need to Clean a Washing Machine

You likely have most of these at home already:

  • Washing machine cleaner tablets or powder, or regular household bleach
  • Microfiber cloths
  • An old toothbrush or small scrub brush
  • A shallow tray or baking dish and a towel (for the drain filter)
  • Rubber gloves
  • Mild dish soap and warm water

Safety note: Never mix bleach with vinegar, ammonia or other cleaners. Combining them can release toxic gases. If you use both on different days, run a rinse cycle in between.

How to Clean a Front Load Washing Machine Step by Step

1. Wipe and Inspect the Door Gasket

Pull back the rubber seal around the door opening. You will often find lint, hair, socks, coins and dark spots. Wipe out debris, then scrub the folds with a cloth dipped in warm, soapy water or a diluted bleach solution. Dry the gasket thoroughly when finished.

2. Remove and Wash the Detergent Drawer

Most drawers release with a small tab. Soak it in warm, soapy water, scrub the corners with a toothbrush, and clean the cavity where the drawer slides in. This spot often hides the slimiest buildup.

3. Clean the Drain Pump Filter

Check your manual first. The filter usually sits behind a small panel at the bottom front of the machine. Place a towel and a shallow tray underneath because water will drain out. Unscrew the filter slowly, remove lint and debris, rinse it, and twist it back in firmly.

4. Run an Empty Hot Cleaning Cycle

Use the “Tub Clean,” “Clean Washer” or hottest setting. Add a washer cleaner tablet to the drum or the amount of bleach your manufacturer recommends to the bleach dispenser. Many brands, including LG, Samsung and Whirlpool, suggest running a tub cleaning cycle about once a month.

5. Wipe Down and Air Dry

After the cycle ends, wipe the drum, door glass and gasket with a dry cloth, then leave the door and drawer open for several hours.

How to Clean a Top Load Washing Machine Step by Step

1. Clean the Rim, Lid and Dispensers

Wipe under the lid and around the top rim of the tub where scum collects. Remove and soak removable fabric softener or bleach dispensers.

2. Scrub Around the Agitator

If your machine has an agitator, clean around its base with a brush. Some agitators have a removable cap or top section where residue hides.

3. Run a Hot Cleaning Cycle

Select the clean washer setting or the hottest, largest load. Add a washer cleaner or bleach as your manual directs. On older top loaders, some people pause the cycle once the tub fills to let the solution soak for about an hour before finishing.

4. Leave the Lid Open

Let the tub air dry completely before your next load.

Is Vinegar or Baking Soda Good for Cleaning a Washer?

Short answer: Vinegar and baking soda can help freshen a washer and loosen mild mineral buildup, but they are not strong disinfectants. Some appliance manufacturers advise against regular vinegar use because repeated exposure may wear rubber seals and hoses. Check your manual before using either.

Here is a practical way to think about your options:

MethodBest ForLimitations
Commercial washer cleanerMonthly maintenance, odor and residueOngoing cost
Bleach cycleDisinfecting and heavy musty odorsCannot be mixed with other cleaners; not for every finish
White vinegarMild odors and mineral depositsMay affect rubber parts with frequent use
Baking sodaLight deodorizingLittle cleaning power on heavy buildup

In our experience, the method matters less than the habits. A washer cleaned monthly and left open to dry rarely develops a serious smell, no matter which cleaner you use.

How Often Should You Clean a Washing Machine?

Short answer: Run a full cleaning cycle about once a month, wipe the door gasket weekly, and clean the drain filter every few months. Large households, pet owners and anyone who washes mostly in cold water may need to clean more often.

TaskHow Often
Leave door or lid open to dryAfter every load
Wipe door gasket (front load)Weekly
Clean detergent drawerEvery 2 to 4 weeks
Run tub clean cycleMonthly
Clean drain pump filterEvery 3 months, or sooner if draining slows
Check hoses for cracks or bulgesEvery 6 to 12 months

Habits That Keep Your Washer From Smelling Again

Cleaning removes the smell. These habits keep it from coming back.

  1. Use the right detergent. If you have a high efficiency (HE) washer, use HE detergent only.
  2. Measure, do not guess. Most loads need far less detergent than the cap line suggests. Too many suds leave residue behind.
  3. Cut back on liquid fabric softener. Try wool dryer balls or use softener only occasionally.
  4. Move laundry out promptly. Transfer wet clothes to the dryer within an hour or so when possible.
  5. Leave the door and drawer open. This is the single most effective odor prevention habit.
  6. Wipe the gasket after heavy loads. Towels and bedding leave the most lint behind.
  7. Run a warm or hot cycle now and then. Occasional warmer washes help dissolve greasy buildup.
  8. Keep the laundry area ventilated. In humid Hampton Roads summers, a small fan or dehumidifier near the washer helps everything dry faster.

Common Mistakes to Avoid

  • Mixing cleaners. Bleach plus vinegar or ammonia is dangerous. Use one at a time.
  • Ignoring the drain filter. A clogged filter can cause standing water, odors and slow draining.
  • Using regular detergent in an HE washer. It creates excess suds that do not rinse properly.
  • Covering the smell with fragrance. Scent boosters mask odors without removing their source.
  • Overloading the drum. Packed loads do not rinse well and leave more residue behind.
  • Closing the door right after a cycle. Moisture trapped inside is exactly what odor causing bacteria need.

When Should You Call a Professional?

Most washer odors respond to cleaning and better habits. Contact a qualified appliance technician if you notice:

  • Standing water after every cycle, even with a clean filter
  • A burning or electrical smell
  • Leaks under or behind the machine
  • A sewage smell that may point to a drain or plumbing issue
  • Odors that return within days despite monthly cleaning

These signs can indicate a drainage, hose or pump problem that cleaning alone will not solve.

Key Takeaways

  • Washer odors usually come from detergent and softener residue that bacteria and mold feed on.
  • Front load washers smell more often because the door gasket traps moisture.
  • Clean the gasket weekly, run a hot tub cleaning cycle monthly, and clear the drain filter every few months.
  • Leaving the door and detergent drawer open after each load is the simplest way to prevent odors.
  • Use HE detergent in HE machines and measure carefully, since too much soap causes buildup.
  • Never mix bleach with vinegar or ammonia.
  • Humid coastal climates like Norfolk’s make drying habits even more important.

Frequently Asked Questions

Why do my towels smell bad after washing?

Towels often smell sour when detergent residue builds up in the washer or in the fibers, or when wet towels sit too long before drying. Clean the machine, use less detergent, skip fabric softener on towels, and dry them promptly. An occasional hot wash also helps remove trapped body oils.

Can I use bleach to clean my washing machine?

Yes, most manufacturers allow bleach in an empty hot cleaning cycle. Add it to the bleach dispenser using the amount your manual recommends. Never combine bleach with vinegar, ammonia or other cleaners, and run an extra rinse cycle afterward if you will be washing dark or delicate clothing next.

How do I get rid of mold on my washer door seal?

Pull back the rubber gasket and remove any lint or debris. Scrub the folds with a toothbrush and a diluted bleach solution or washer cleaner, then rinse and dry completely. Some deep staining may remain even after the mold is cleaned. If the seal is cracked or heavily stained, replacing it may be best.

Should I leave my washing machine door open?

Yes. Leaving the door or lid open after each load lets the drum, gasket and dispenser dry, which prevents musty odors and mold growth. If you have small children or pets, open the door only partway or close the laundry room door to keep everyone safe.

How often should I clean my washing machine filter?

Clean the drain pump filter about every three months in most homes. Check it sooner if the washer drains slowly, leaves clothes soaking wet or shows an error code. Homes with pets, kids or lots of towels may need to clean it monthly because lint and hair collect faster.

Does using cold water cause washing machine odors?

Cold water does not create odors directly, but washing exclusively in cold water allows greasy detergent and softener residue to build up more easily. Keep using cold water for most loads if you prefer, but run a monthly hot cleaning cycle and an occasional warm wash to dissolve that buildup.

Is it safe to clean a washing machine with vinegar?

Vinegar can freshen a washer and loosen light mineral deposits, but it is a weak disinfectant. Some manufacturers advise against frequent vinegar use because it may wear rubber seals and hoses over time. Check your owner’s manual first, and never mix vinegar with bleach in the same cycle.

Why does my washing machine smell like rotten eggs?

A rotten egg or sewage smell often points to bacteria in the drain hose, a clogged drain filter or a plumbing issue such as a dry trap or blocked vent. Clean the filter and run a hot cleaning cycle first. If the smell continues, have a plumber or appliance technician inspect the drain.

Conclusion

A smelly washing machine is rarely a sign that something is broken. In most cases it simply needs the same attention the rest of your home gets: a monthly hot cleaning cycle, a quick wipe of the gasket and drawer, a clean drain filter, and the habit of leaving the door open. Those small steps keep your laundry fresh and help your machine last longer, which matters even more in humid coastal homes across Norfolk and Hampton Roads.
