Smelly Towels and Skin Health: How Often to Wash Towels and Get Rid of Musty Odors
There is something especially unpleasant about stepping out of a refreshing summer shower and reaching for a towel that smells damp, sour, or musty.
That odor isn't always just a laundry problem.
A towel repeatedly exposed to moisture, dead skin cells, body oils, sweat, and bathroom humidity can create an environment where microorganisms survive and multiply more easily.
That doesn't mean every slightly used towel will make you sick. But poor towel hygiene may become more important if you have eczema, acne-prone skin, cuts, fungal infections, a weakened skin barrier, or a household member who is sick.
Wash bath towels regularly, let them dry completely between uses, avoid sharing towels when someone has a contagious skin condition or infection, and don't keep using a towel that smells musty even after laundering.
Why Do Towels Start Smelling?
Towels are designed to absorb water—which is exactly what makes them useful.
Unfortunately, that absorbency also means they can stay damp for hours after a shower, especially in humid bathrooms or during hot summer weather.
Every time you dry your body, the towel may pick up:
- Moisture
- Dead skin cells
- Natural skin oils
- Sweat
- Microorganisms normally found on your skin
- Small amounts of bathroom debris
When a towel stays wet for a long time, bacteria, yeasts and molds have more favorable conditions to persist.
That familiar musty towel smell is therefore a good practical sign that it's time for the towel to be washed and fully dried.
Can Dirty Towels Actually Affect Your Skin?
For most healthy people, occasionally reusing a bath towel is unlikely to cause a serious skin problem.
But towels can act as a temporary reservoir for microorganisms and debris.
The risk becomes more important when:
- Your towel stays damp between uses
- You share towels with other people
- You have cuts, scrapes or open sores
- You have eczema or another damaged skin barrier
- You have athlete's foot, ringworm or another fungal infection
- Someone in your household has a contagious infection
- You leave sweaty gym towels in a closed bag for hours
Healthcare experts note that contaminated personal items, including towels, can play a role in spreading some bacterial, fungal and viral infections.
Can Dirty Towels Cause Acne?
This is one of the most common towel-related skin questions.
A dirty towel is not usually the primary cause of acne.
Acne is influenced by several factors, including clogged pores, oil production, inflammation, hormones and bacteria living in the follicles.
However, repeatedly rubbing your face with a dirty, oily or heavily fragranced towel may irritate sensitive skin or transfer additional residue onto your face.
If you are acne-prone, using a clean face towel and gently patting rather than aggressively rubbing your skin is a sensible habit.
Can Towels Spread Staph or MRSA?
Under the right circumstances, yes.
Staph bacteria can spread through direct skin contact as well as contaminated personal items.
That is why health authorities commonly advise people not to share towels, razors, clothing or similar personal items when dealing with certain skin infections.
People with cuts, draining wounds, abscesses or known MRSA infections should be especially careful about towel sharing and laundry hygiene.
How Often Should You Wash Bath Towels?
There is no universal number of uses that works for every person and every home.
A practical recommendation from Cleveland Clinic dermatology guidance is to wash or replace your bath towel at least once a week.
You may need to wash it more often if:
- Your bathroom is humid
- The towel doesn't fully dry between showers
- You shower more than once a day
- You sweat heavily
- You have a skin infection
- You have eczema, sores or broken skin
- You are currently sick
In very humid conditions, washing bath towels two or three times per week may be more appropriate.
How Often Should You Wash Hand Towels?
Hand towels often get used far more frequently than bath towels.
They may also stay damp because several household members use them throughout the day.
As a general rule, changing hand towels at least weekly is reasonable, but busy household towels may need to be changed more frequently.
If someone in the home is sick, more frequent washing is a smart precaution.
Washcloths Need More Frequent Cleaning
Washcloths are different because they directly scrub the skin and can collect makeup, oils, dead skin and product residue.
Cleveland Clinic recommends replacing or washing washcloths at least a couple of times per week.
For facial cleansing, many people with sensitive or acne-prone skin may prefer using a fresh washcloth more frequently.
Gym Towels Should Be Washed Even More Often
Gym towels face a different environment entirely.
They absorb sweat, touch exercise equipment and often get tossed into a warm, closed gym bag.
That combination of heat and moisture makes prompt washing especially important.
Don't leave a damp workout towel balled up in your gym bag until the next day. Take it out as soon as possible, wash it, or spread it out so it can dry.
The Biggest Mistake: Leaving Towels Damp
You don't necessarily need a freshly washed towel after every single shower.
What matters tremendously is what happens between uses.
If you leave your towel crumpled:
- On the bathroom floor
- In a laundry pile
- Inside a gym bag
- On the edge of the bathtub
- Hanging in a tight bundle
it may remain damp much longer.
Instead, spread it out on a towel bar or drying rack where air can circulate around as much of the fabric as possible.
Why Summer Makes Smelly Towels Worse
Hot weather isn't necessarily the problem by itself.
The bigger issue is humidity.
When indoor air already contains a lot of moisture, water evaporates from towels more slowly.
That means your towel can stay damp much longer after a shower.
Summer towel odor is therefore especially common in:
- Poorly ventilated bathrooms
- Homes without air conditioning
- Coastal climates
- Basement bathrooms
- Small bathrooms without exhaust fans
Opening the bathroom door after a shower, running the exhaust fan and spreading towels out can make a noticeable difference.
How to Wash Towels Properly
You don't need an elaborate sanitizing routine for normal household towels.
The CDC's basic household laundry guidance is surprisingly simple:
- Use laundry detergent
- Follow the towel manufacturer's care instructions
- Use an appropriate water temperature
- Dry the items completely
For most households, proper washing and complete drying are more important than trying to disinfect every towel after every use.
Do Towels Need to Be Washed Separately?
Not necessarily.
A common online claim says towels must always be separated from underwear, clothing or other laundry because of bacteria transfer.
That isn't a universal public-health requirement.
The CDC states that it is generally safe to wash dirty laundry from a sick person together with other people's laundry when normal laundering procedures are followed.
You may still choose to separate towels for practical reasons, such as:
- Preventing lint from sticking to clothing
- Using a different wash temperature
- Preventing heavy towels from damaging delicate fabrics
- Optimizing drying time
But routine separation isn't required simply because towels contain bacteria.
Should You Use Hot Water?
Check the towel's care label first.
The CDC recommends using the warmest appropriate water setting for washable items when enhanced hygiene is needed.
For everyday household laundry, modern detergent plus an appropriate wash cycle and thorough drying can be effective.
The hottest possible cycle is not always necessary—and excessive heat can shorten the lifespan of certain fabrics.
Is Fabric Softener Bad for Towels?
Using too much fabric softener may leave residue on towel fibers.
Over time, that coating can interfere with the towel's ability to absorb water efficiently.
Heavy buildup from softeners, scent boosters and excess detergent may also contribute to towels feeling waxy or developing persistent odors.
If your towels aren't absorbing as well as they used to, reducing fabric softener may help.
Can Vinegar Remove Musty Towel Smell?
White vinegar is often recommended online as a household deodorizer.
But don't assume that adding vinegar to every laundry cycle is necessary or appropriate for every washing machine.
Some appliance manufacturers discourage repeated use of acidic products because they may affect rubber components over time.
Before using vinegar, check your washing machine manual and your towel's care label.
For persistent odor, the first things to address are usually:
- Using the correct amount of detergent
- Not overloading the washer
- Drying towels completely
- Cleaning the washing machine if needed
- Not leaving wet towels sitting for hours
What About Bleach?
For towels that can safely tolerate it, bleach may be useful in certain circumstances.
This is particularly relevant when someone has an infectious illness or when laundry requires additional sanitizing.
However, always check:
- The towel care label
- The bleach product instructions
- Your washing machine instructions
Never mix bleach with vinegar, ammonia or other household cleaning chemicals.
Why Do My Towels Still Smell After Washing?
If freshly washed towels still smell sour or musty, several things may be happening.
| Possible Cause | What to Try |
|---|---|
| Too much detergent | Use the manufacturer-recommended amount. |
| Washer overloaded | Give towels enough space to rinse thoroughly. |
| Towels stored damp | Dry completely before folding or storing. |
| Dirty washing machine | Run the manufacturer's recommended cleaning cycle. |
| Fabric softener buildup | Reduce or temporarily skip softener. |
| Old towel with persistent odor | Consider replacing it if laundering no longer removes the smell. |
Should You Share Bath Towels?
In many healthy households, occasional towel sharing between partners may not automatically cause a problem.
But there are situations where sharing should be avoided.
Don't share towels if someone has:
- Ringworm
- Athlete's foot
- Warts
- A draining skin infection
- MRSA
- Open wounds
- A contagious illness
Children should generally have their own towels as well, particularly because cuts, scrapes and inconsistent hand hygiene are common.
Face Towels Deserve Extra Attention
Your facial skin may be more sensitive than the skin on your arms or legs.
A towel that contains makeup residue, hair products, oils or fragrance may trigger irritation in some people.
For healthier facial skin:
- Use a clean towel
- Avoid sharing it
- Pat your face instead of rubbing vigorously
- Use fragrance-free laundry products if your skin is sensitive
- Make sure the towel dries fully between uses
Are Cotton Towels Better for Sensitive Skin?
Soft cotton towels are often comfortable for sensitive skin because they can be gentle and absorbent.
But the most important factor is not the fiber alone.
A clean, soft towel used gently is usually preferable to a rough towel that aggressively scrapes your skin.
If you have eczema or easily irritated skin, patting instead of vigorous rubbing can reduce mechanical irritation.
When Should You Replace a Towel?
There is no medical rule saying bath towels must be replaced every six months or once a year.
Replacement depends more on condition than calendar age.
Consider replacing a towel when:
- It has a persistent musty smell after proper washing
- It has become extremely rough
- It no longer absorbs water well
- The fibers are heavily worn or damaged
- Visible mildew staining doesn't come out
A well-maintained quality towel may last much longer than an arbitrary one-year replacement schedule.
Simple Summer Towel Routine

If It Smells
Don't keep using it. Wash it and dry it completely.
At Least Weekly
Rotate in a clean bath towel, and wash more frequently if your environment is humid.
After the Gym
Remove damp towels from your bag as soon as possible.
If Someone Is Sick
Increase laundry hygiene and avoid sharing personal towels.
Frequently Asked Questions
How often should I wash my bath towel?
A practical general rule is at least once a week. Wash it more often if it doesn't dry completely, your home is humid, you're sick or you have damaged skin.
Is it bad to use a towel that smells musty?
A persistent musty smell is a sign that the towel needs washing and thorough drying. If the odor remains after proper laundering, consider replacing the towel.
Can dirty towels cause fungal infections?
Contaminated towels can potentially help spread certain fungal infections, especially when towels are shared or remain damp. People with athlete's foot, ringworm or similar infections should use their own towels.
Can dirty towels cause acne?
Dirty towels are not considered a primary cause of acne, but oils, residue, friction and contaminated fabric can potentially irritate acne-prone or sensitive skin.
Should I wash towels after every use?
Most healthy adults don't need to wash a bath towel after every shower if it is allowed to dry completely between uses. Gym towels, washcloths and towels used during illness often need more frequent washing.
Should towels be washed separately from clothes?
Not for hygiene reasons in most households. Washing towels separately can still be useful for fabric care, lint control and choosing the best cycle.
Why do my towels smell even after washing?
Common causes include detergent buildup, fabric softener residue, an overloaded washer, incomplete drying, a dirty washing machine or storing towels while they are still damp.
The Bottom Line
A smelly towel isn't automatically a health emergency, but it's also not something you should ignore.
Towels naturally collect moisture, oils, dead skin and microorganisms. The longer they remain damp, the more favorable the environment becomes for microbial survival.
The good news is that keeping towels fresh doesn't require obsessive cleaning.
Focus on a few simple habits:
- Wash bath towels regularly
- Wash them more frequently in humid conditions
- Dry towels completely between uses
- Don't leave wet towels in piles or bags
- Avoid sharing towels during infections
- Use detergent according to directions
- Limit unnecessary product buildup
- Replace towels that remain musty after proper cleaning
During summer, the single biggest upgrade may simply be helping your towels dry faster between showers.
Fresh towels feel better, smell better and help keep your everyday skin-care routine cleaner and more comfortable.
