1. What Causes Mildew and Musty Smell in Beach Towels?

First, it helps to understand why your beach towel smells in the first place. Once you know the cause, the solution becomes much easier to remember.

The Science Behind the Smell

Mildew is a type of mold. It grows on damp surfaces. When a towel stays wet for too long, tiny bacteria and mold spores start to grow inside the fibers. They form a layer called a biofilm. That biofilm is what causes the musty smell you notice.

A 6-month study of 26 households found something eye-opening. Towels developed noticeable odour after just 2 months of regular use. The biofilm kept building up over the full 6 months. The main bacteria found were from groups called Gammaproteobacteria, Alphaproteobacteria, and Actinobacteria. Interestingly, these are environmental bacteria โ€” not just the normal bacteria from your skin.

“Regular detergent alone cannot always break down biofilm. Over time, odour builds up even in towels that are washed regularly.”

Why Beach Towels Are Worse Than Regular Towels

Beach towels face extra challenges compared to regular bath towels. Here is why they smell faster:

  • ๐Ÿ–๏ธ Salt water soaks deep into the fibers and encourages bacterial growth
  • ๐Ÿงด Sunscreen and body oils coat the fibers, giving bacteria extra food to eat
  • ๐ŸŒŠ Sand particles get trapped in the loops, holding moisture longer
  • ๐Ÿคธ Sweat adds more organic material for bacteria to feed on
  • ๐ŸŽ’ Being stuffed in a wet bag after use speeds up mildew growth dramatically

Furthermore, fabric softeners make things worse. They leave a waxy coating on the fibers. That coating traps bacteria and reduces how well the towel absorbs water. As a result, the musty smell comes back faster after each wash.

โš ๏ธ Key Fact: Mildew can start growing on a damp towel in as little as 24โ€“48 hours. Therefore, how you handle your towel after the beach matters just as much as how you wash it.

2. Is a Musty Beach Towel Dangerous for Your Skin?

This is a great question โ€” and one many people don’t think to ask. A smelly towel is not just unpleasant. It can also be a real hygiene concern.

According to one commonly cited lab test, 9 out of 10 towels tested contained bacteria. Even more alarming, some tested positive for E. coli. That is a bacteria most people associate with food poisoning.

However, does that mean a smelly towel will make you sick? Here is a helpful breakdown:

Who Is at Risk?Level of ConcernRecommended Action
Healthy adultsLow โ€” unlikely to get sick from a mildly musty towelDeep clean the towel as soon as possible
People with acne or eczemaMedium โ€” bacteria can worsen skin flare-upsReplace heavily mildewed towels; wash after each use
Children and babiesMedium-High โ€” more sensitive skin and immune systemsAlways use freshly washed, fully dry towels
People with weak immunityHigh โ€” greater risk of skin infectionsDiscard badly mildewed towels immediately
๐Ÿšจ Important: If your towel has visible black, green, or yellow mildew spots, stop using it on your skin right away. Deep clean it first, or replace it. Using a mouldy towel can spread bacteria to your face and body.

In summary, a slightly musty towel probably won’t send you to the doctor. But it is still worth fixing. Additionally, for families with children or anyone with sensitive skin, keeping beach towels clean is especially important.

3. Step-by-Step: How to Remove Mildew Smell from Beach Towels

Now for the main event. Here are the three best methods to get rid of mildew smell from beach towels. Start with Method 1. If the smell is still there, move to Method 2 or 3.

โœ… Method 1 โ€” Vinegar & Baking Soda Soak (Best for Most Cases)

This is the most popular and most effective natural method. It works for most smelly beach towels. Furthermore, it uses items you already have at home.

1
Fill a tub or large bucket with hot water. Make the water as hot as the towel’s care label allows.
2
Add 1 cup of white vinegar and ยฝ cup of baking soda. Stir until the baking soda dissolves.
3
Submerge the smelly beach towels. Let them soak for 1โ€“2 hours. Longer is better for strong odors.
4
Transfer the towels to your washing machine. Wash on the hottest setting with your regular detergent. Do NOT add fabric softener.
5
Dry completely right away. Use a dryer on high heat, or hang in direct sunlight. Do not let them sit damp in the machine.
๐Ÿ’ก Pro Tip: Never mix vinegar and baking soda in the washing machine at the same time. They cancel each other out. Instead, use the soak method above where they work together in large amounts of hot water.

โœ… Method 2 โ€” Hot Wash with Oxygen Bleach (Color-Safe Option)

This method is great for colorful beach towels that you cannot bleach. Oxygen bleach is gentler than regular bleach. However, it is still very powerful against mildew and bacteria.

1
Check your towel’s care label for the maximum safe water temperature.
2
Add oxygen bleach powder (such as OxiClean) to your washing machine along with your usual detergent.
3
Run the hottest wash cycle your towel can handle. Skip the fabric softener โ€” it will undo the cleaning.
4
Dry immediately on high heat or in the sun. Check that every part of the towel is fully dry before folding.

โœ… Method 3 โ€” Bleach Soak for Heavy Mildew (White Towels Only)

This method is for the worst cases โ€” towels with heavy mildew, visible staining, or a smell that just won’t go away. Use this only on white or bleach-safe towels.

1
Mix ยผ cup of disinfecting bleach per gallon of cool water in a bucket. Never use hot water with bleach.
2
Soak the towels for 5 minutes only. Do not soak longer โ€” this can weaken the fabric fibers.
3
Wash in hot water with your regular detergent plus โ…“ cup of bleach added to the bleach dispenser.
4
Rinse thoroughly and dry completely right away.
๐Ÿšจ WARNING: Never mix bleach with vinegar, baking soda, or ammonia. This creates toxic fumes. Always use bleach alone with detergent only.

4. Natural Methods: Vinegar, Baking Soda and Sunlight

Many people prefer to remove musty smell from beach towels without harsh chemicals. Thankfully, there are several powerful natural options. Let’s look at each one in more detail.

๐Ÿถ White Vinegar โ€” The Odour Neutralizer

White vinegar is mildly acidic. That acid helps break down mineral deposits and detergent buildup. It also changes the pH of the fabric, making it harder for bacteria to survive. Therefore, it is one of the best natural tools against mildew smell.

  • Use distilled white vinegar only (not apple cider vinegar)
  • Add to the fabric softener compartment for a rinse-cycle boost
  • Or use in the pre-soak method above for stronger results
  • Do not use if your washing machine has a warning against vinegar (some front-loaders do)

๐Ÿฅ„ Baking Soda โ€” The Odour Absorber

Baking soda is alkaline. It works in the opposite way to vinegar. Together, they tackle the odour from both sides. Baking soda also helps soften the water, which makes your detergent work better.

  • Add ยฝ cup directly to the drum with your towels
  • Works well as a pre-soak ingredient
  • Also great sprinkled on towels before a quick machine wash

โ˜€๏ธ Sunlight โ€” Nature’s Free Disinfectant

Sunlight is one of the most underused tools in laundry care. The UV rays in sunlight help kill bacteria and mould spores naturally. In addition, sunlight leaves towels smelling fresh without any chemicals at all.

“Hang your beach towels in direct sunlight after washing. The UV light acts as a natural disinfectant. It also helps get rid of any lingering musty odour.”
  • Hang towels fully spread out, not folded over a rail
  • Both sides of the towel should get direct sun
  • Bring them in as soon as they are fully dry to avoid stiffness
  • Even on a cloudy day, outdoor drying is better than indoor drying

5. Deep Cleaning: When to Use Bleach or Oxygen Bleach

Sometimes natural methods are not enough. If your beach towel has heavy mildew or visible staining, you may need a deeper approach. Here is how to decide which type of bleach to use.

Regular Bleach vs. Oxygen Bleach โ€” What Is the Difference?

๐Ÿงด Regular Chlorine Bleach

  • Very strong disinfectant
  • Best for white towels only
  • Can damage fibers if overused
  • Use cool water (never hot)
  • Maximum soak: 5 minutes
  • Recipe: ยผ cup per gallon of water

๐ŸŒฟ Oxygen Bleach (OxiClean etc.)

  • Gentler on fabric and color
  • Safe for colored towels
  • Works well with hot water
  • No toxic fumes
  • Use with regular detergent
  • Great for regular deep-cleaning

According to laundry experts at Good Housekeeping, oxygen bleach is generally the safer choice for most fabrics. However, for severe mildew on white cotton towels, chlorine bleach remains the most powerful option when used correctly.

โš ๏ธ Reminder: Always skip fabric softener after a bleach wash. Fabric softener can leave a coating that reduces the bleach’s effectiveness and traps more bacteria over time.

6. How to Get the “Wet Dog” Smell Out of Towels

That funky, sour smell that some people call a “wet dog” odour is actually very common in beach towels. It is different from a typical musty mildew smell. However, the fix is similar.

What Causes the “Wet Dog” Smell?

The “wet dog” smell usually comes from a combination of three things:

  1. Old detergent residue trapped deep inside the towel fibers
  2. Fabric softener buildup that coats the fibers and locks in odour
  3. Body oils and sunscreen that were never fully rinsed out

When the towel gets wet again, all of that trapped residue releases its smell at once. That is why your towel can smell fine when dry โ€” but awful when wet.

How to Fix the “Wet Dog” Smell in 3 Steps

1
First wash: strip the residue. Wash the towel on hot with no detergent and no fabric softener. This helps rinse out old soap buildup first.
2
Second wash: kill the bacteria. Follow up with either the vinegar/baking soda soak or a hot wash with oxygen bleach.
3
Dry on high heat or in sunlight until every part of the towel is fully dry. Then never use fabric softener again on beach towels.
๐Ÿ’ก Going forward: Replace liquid fabric softener with white vinegar in the rinse cycle. It naturally softens towels without the residue buildup that causes the “wet dog” smell.

7. How Often Should You Wash Beach Towels to Avoid Mildew?

One of the simplest ways to prevent a smelly beach towel is to wash it often enough. But how often is “often enough”?

The Simple Rule for Beach Towels

“Wash your beach towel after every full beach or pool day. Unlike bath towels, beach towels collect sand, salt, sunscreen, and sweat โ€” all of which speed up bacterial growth.”

Here is a quick comparison to help you remember:

Towel TypeRecommended Wash FrequencyWhy?
Beach TowelAfter every useSalt, sand, sunscreen, and sweat build up fast
Bath TowelEvery 3โ€“4 usesUsed on a clean body; dries faster indoors
Pool TowelAfter every useChlorine residue plus moisture traps bacteria
Gym TowelAfter every useHeavy sweat absorption; quick odour build-up

Furthermore, research supports this advice. The 6-month household study showed that towel odour and biofilm started developing after just 2 months with regular use. That means even “regularly washed” towels can build up bacteria if they are not dried properly between uses.

8. Best Way to Dry Beach Towels Indoors and Outdoors

Washing your towel correctly is only half the battle. How you dry it is just as important. In fact, improper drying is the number one reason mildew smell comes back after washing.

โ˜€๏ธ Drying Outdoors

  • Hang fully spread out on a clothesline or railing โ€” not folded over
  • Make sure both sides get direct sunlight and air flow
  • Bring in as soon as dry โ€” over-drying in heat can stiffen fibers
  • Even on a cloudy day, outdoor air circulation is helpful

๐Ÿ  Drying Indoors (Dryer or Air Dry)

  • Use the highest heat setting that is safe for your towel’s fabric
  • Do not overload the dryer โ€” towels need room to tumble and dry evenly
  • Remove towels immediately when done โ€” leaving them inside causes musty smells
  • If air-drying indoors, use a fan or open a window for airflow
  • Make sure the towel is 100% dry before folding or putting away
โš ๏ธ Never Do This: Do not leave a wet beach towel in a car trunk, gym bag, or beach bag for more than a couple of hours. That warm, humid environment is the perfect place for mould and bacteria to grow very quickly.

9. Storage Mistakes That Make Beach Towels Smell Musty

Even a perfectly clean beach towel can start to smell if you store it the wrong way. Therefore, proper storage is one of the most overlooked steps in towel care.

Common Storage Mistakes (And How to Fix Them)

  • โŒ Folding a slightly damp towel โ†’ Always make sure towels are 100% dry first
  • โŒ Storing in a plastic bag or airtight container โ†’ Use breathable cotton bags or open shelves instead
  • โŒ Piling towels on top of each other tightly โ†’ Stack loosely or hang them to allow air flow
  • โŒ Keeping towels in a damp bathroom cabinet โ†’ Store in a dry, well-ventilated area only
  • โŒ Leaving a towel on a hook for weeks between uses โ†’ Wash and fully dry before storing away seasonally
  • โŒ Storing near wet swimwear or equipment โ†’ Keep towels in a separate, dry area
๐Ÿ’ก Best Practice: For long-term storage (like off-season), wash your beach towels first. Then fold them loosely. Finally, place them in a breathable cotton storage bag. This prevents dust buildup and keeps mildew away.

10. Fabric Matters: Do Certain Beach Towels Smell Less? (Cotton vs Microfiber)

Yes โ€” the fabric of your beach towel makes a big difference in how quickly it develops odour. As a beach towel manufacturer with 15 years of experience, Favor Houseware can explain exactly why.

Cotton Terry โ€” Classic but Slower to Dry

Traditional terry cotton towels are thick, soft, and absorbent. However, they hold onto moisture longer. That extra drying time gives bacteria more time to grow. As a result, heavy cotton terry towels are more prone to mildew if not dried thoroughly.

  • โœ… Soft and very absorbent
  • โœ… Great for sensitive skin
  • โŒ Slower to dry โ€” higher mildew risk
  • โŒ Heavier to carry to the beach

Turkish Cotton โ€” The Best of Both Worlds

Our Turkish hammam towels use a flat-weave construction. This makes them much lighter and faster to dry than traditional terry. Furthermore, they get softer with every wash. Because they dry faster, they resist mildew buildup better in real-world use.

  • โœ… Dries 2โ€“3x faster than terry
  • โœ… Gets softer over time
  • โœ… Lighter and more packable
  • โœ… Lower mildew risk due to faster drying

Microfiber โ€” Fastest Drying Option

Our microfiber beach towels are made from ultra-fine synthetic fibers. They dry extremely fast โ€” often within 1โ€“2 hours of use. Therefore, they are the best choice for people who tend to forget to hang their towel right away.

  • โœ… Fastest drying time of all towel types
  • โœ… Compact and lightweight for travel
  • โœ… Lowest mildew risk when cared for properly
  • โš ๏ธ Less soft than cotton โ€” personal preference varies
  • โš ๏ธ Must still be washed regularly to remove sunscreen and salt residue

What to Look for When Buying (Manufacturer’s Advice)

When choosing a new beach towel, here are the key factors that affect mildew resistance:

FeatureWhat to Look ForWhy It Matters
GSM (weight)300โ€“400 GSM for beach towelsLighter weight = faster drying = less mildew
Weave typeFlat weave or waffle weaveMore air flow, faster drying than thick terry
Yarn qualityLong-staple cotton or premium microfiberStronger fibers stay cleaner longer
Finishing treatmentNo harsh chemical coatingsClean finishes absorb better and resist residue buildup
CertificationsOEKO-TEX 100, BSCI, SGSEnsures safe, tested materials with no harmful substances

11. Quick Fixes at the Beach: What to Do With a Wet Towel in the Car

We have all been there. The beach day is over, the towel is still soaking wet, and you have a long drive home. So what is the best way to handle a wet beach towel on the go?

In the Car

  • ๐Ÿš— Lay the towel flat over the back seat or trunk edge โ€” not scrunched up
  • ๐ŸŒฌ๏ธ Open a window slightly to let air flow through the car
  • โ„๏ธ If you have A/C, run it to reduce humidity inside the car
  • โฑ๏ธ Aim to take the towel out of the car within 2โ€“3 hours max
  • ๐Ÿงด Carry a small microfiber towel as a backup โ€” they dry much faster in transit

In Your Beach Bag

  • Never stuff a wet towel in a sealed plastic bag unless it is less than 2 hours to home
  • Use a mesh bag or open tote to carry wet towels โ€” airflow reduces mildew growth
  • Separate the wet towel from your dry clothes and belongings
  • Shake out sand before folding to reduce trapped moisture in the fibers
๐Ÿ’ก Smart Swap: Consider bringing a microfiber beach towel to the beach instead. They dry so quickly that by the time you reach your car, the towel may already be mostly dry. That means zero mildew risk on the drive home.

13. When to Replace a Smelly Beach Towel

Sometimes, even your best efforts are not enough. A towel that has been neglected for a long time may be beyond saving. Here is how to know when it is time to let go and get a new one.

Replace Your Beach Towel Ifโ€ฆ

  • You have tried 3 or more deep-clean cycles and the smell is still there
  • There are visible black, green, or yellow stains that won’t wash out
  • The towel feels rough or stiff even after washing (fiber damage from mould)
  • The towel is less absorbent than it used to be
  • There are thin or worn patches where the fabric is breaking down
  • The towel smells fine when dry but smells awful as soon as it gets wet (deep biofilm)
“Over time, biofilm and mildew can penetrate deep into the towel fibers. Even if you reduce the smell, the towel may stay discoloured, less absorbent, and less hygienic than a new one.”

When it is time for a fresh start, consider upgrading to a higher-quality towel. A well-made beach towel โ€” with good yarn, the right weave, and proper finishing โ€” will resist mildew much longer than a cheap alternative. Check out our wholesale beach towels starting from just 100 pieces.

FAQ: People Also Ask About Smelly Beach Towels

Here are the most common questions people search for about removing mildew from beach towels โ€” answered clearly and simply.

Q1: What causes mildew and musty smell in beach towels?
Beach towels smell musty when they stay damp and warm. That creates a perfect place for bacteria and mould to grow. Sand, sweat, body oils, and sunscreen give those microorganisms extra food. Over time, they form a layer called biofilm inside the fibers. This causes both dullness and a stronger odour after a few months of use โ€” especially if towels are not fully dried between uses.
Q2: Are smelly or moldy towels bad for your skin?
Smelly towels usually mean bacterial contamination. One report found that 9 out of 10 towels tested had bacteria, and some even had E. coli. Most healthy adults won’t get sick from a mildly musty towel. However, it can irritate sensitive skin and worsen acne or eczema. For children or anyone with a weaker immune system, it is always safer to deep-clean or replace badly mildewed towels.
Q3: How do you get mildew smell out of beach towels?
Step-by-step to remove mildew smell from beach towels:
1. Wash once on hot with regular detergent to remove surface dirt.
2. For stubborn mildew, pre-soak in 1 cup white vinegar + ยฝ cup baking soda in hot water for 1โ€“2 hours, then wash again.
3. For white towels with heavy mildew, soak in ยผ cup bleach per gallon of cool water for 5 minutes, then hot-wash with detergent and โ…“ cup bleach.
4. Dry completely in a hot dryer or direct sunlight. Any remaining moisture will bring the smell back.
Q4: What is the best natural way to remove musty smell from towels?
The most popular natural method combines white vinegar and baking soda. Soak towels in hot water with 1 cup of vinegar and ยฝ cup of baking soda for 1โ€“2 hours. Then rinse and wash as usual. Vinegar dissolves mineral and detergent buildup. Baking soda neutralizes odours. Together they lift the musty smell naturally. Afterwards, sun-drying adds a mild antibacterial effect thanks to UV light.
Q5: How do you get the “wet dog” smell out of towels?
That “wet dog” odour is usually caused by old detergent residue, fabric softener buildup, and trapped body oils. First, wash towels once on hot with NO detergent or fabric softener to strip the residue. Next, follow up with a vinegar-baking soda soak or an oxygen bleach wash. Finally, dry on high heat or in the sun. Stop using liquid fabric softener โ€” it makes the problem worse.
Q6: How often should you wash beach towels?
Wash beach towels after every single use at the beach or pool. Unlike bath towels (which you can use 3โ€“4 times), beach towels pick up sand, salt, sunscreen, and sweat. Research shows towel odour and biofilm start building after just 2 months of regular use. Therefore, frequent washing plus thorough drying is essential to avoid musty smells.
Q7: How should you dry beach towels to prevent mildew?
The key is speed and full dryness. Hang towels fully spread out โ€” never folded โ€” in a well-ventilated area or direct sunlight right after use. A hot dryer cycle or direct sunlight both kill mildew effectively. Never leave wet beach towels in a car trunk or gym bag for more than 2โ€“3 hours. That warm, humid environment is ideal for mould and bacteria growth.
Q8: Why do my towels still smell after washing?
If your towel still smells after washing, the usual causes are: too much detergent, fabric softener buildup, low-temperature washes, or incomplete drying. That residue gives bacteria more places to cling and feed. So even a “clean” towel can smell musty when it gets wet again. A deep-clean cycle with hot water and vinegar or oxygen bleach โ€” plus no fabric softener โ€” usually resets the towel completely.
Q9: Do some fabrics resist mildew and odor better?
Yes. Faster-drying fabrics resist mildew better because they spend less time damp. Microfiber and lightweight Turkish flat-weave cotton towels dry 2โ€“3x faster than heavy terry. That shorter drying window limits bacterial growth. When buying, look for lower GSM (300โ€“400g), flat-weave construction, and quality yarn โ€” these all contribute to a towel that stays fresher longer in real-world use.
Q10: When should you throw away a smelly beach towel?
Replace your beach towel if: the smell remains after 3+ deep-clean cycles, there are visible black or yellow mildew stains that won’t wash out, the towel feels stiff or rough, or it has become noticeably less absorbent. Deep biofilm can penetrate the fibers permanently. At that point, replacing the towel is safer and more hygienic than continuing to use it.

Conclusion: Fresh Beach Towels Start with Good Habits

A smelly beach towel is fixable. And with the right routine, it is also very easy to prevent. Here is a quick summary of everything you have learned:

  • Mildew smell is caused by bacteria and biofilm โ€” not just dirty towels
  • The best natural fix is a vinegar + baking soda soak followed by a hot wash
  • For stubborn cases, use oxygen bleach (colors) or chlorine bleach (white only)
  • Always dry completely โ€” in the sun or on high dryer heat
  • Never use fabric softener on beach towels
  • Wash after every single beach or pool day
  • Store in a dry, breathable, ventilated space
  • If smell won’t go after 3 deep cleans โ€” it is time for a new towel

At Favor Houseware, we believe a great beach towel should stay fresh, soft, and absorbent for years. That is why we build every towel with premium materials, expert construction, and strict quality control.
