3 Ways to Remove Mildew Smell from Towels

A clean towel should smell like… nothing. Not “wet dog.” Not “forgotten gym bag.” Not “mysterious basement breeze.”
If your towels come out of the wash with a mildew smell, you don’t need new towelsyou need a better plan.
The good news: mildew odor is usually fixable because it’s often a mix of (1) trapped body oils + detergent residue and
(2) bacteria/mildew that had way too much time to throw a party while the towel stayed damp.

Below are three reliable, repeatable ways to remove mildew smell from towels (without perfume-bombing them into submission),
plus prevention tips so you don’t have to keep running “Operation: Not Musty” every weekend.

Why Towels Get That Mildew Smell (Even After Washing)

1) Damp time is stink time

Towels are thick, absorbent, and excellent at holding onto moistureaka the exact conditions mildew and odor-causing bacteria love.
If a towel sits wet on the floor, in a hamper, or in a washing machine after the cycle ends, it can develop that sour,
swampy smell fast.

2) Detergent and softener buildup traps odors

Too much detergent, frequent fabric softener, and dryer sheets can leave a coating on towel fibers. That coating can trap oils and grime,
reduce absorbency, and make it harder for water to rinse everything away. The towel looks clean. It smells… suspicious.

3) Your washer might be “seasoning” the load

If your washing machine has residue, mildew, or a funky door gasket (front loaders, we’re looking at you),
it can transfer odors right back onto freshly washed towels. Cleaning the towels without cleaning the washer is like
showering and then putting on yesterday’s sweaty hoodie.

Before You Start: Quick Checklist (So the Fix Actually Works)

• Check the care label for maximum water temperature and bleach warnings.
• Don’t overload the washertowels need room to tumble so water can flush out residue.
• Skip fabric softener while deodorizing (and honestly, consider skipping it long-term for towels).
• Use an extra rinse if your washer has that option.
• Never mix chlorine bleach with vinegar (dangerous fumes). Keep those two in separate universes.

Way 1: The Vinegar Rinse Reset (Great for Buildup + Everyday Musty Smell)

Think of this as hitting the “unclog the fibers” button. White distilled vinegar is widely used to help cut through residue
and deodorize towelsespecially when the issue is trapped detergent/softener plus lingering funk.

Best for

• Towels that smell sour or musty right out of the dryer
• Towels that feel stiff/waxy (a clue there’s buildup)
• Households that accidentally “measure” detergent with vibes instead of the cap

Step-by-step

1. Put towels in the washer (no clothes, no fabric softener, no dryer sheets later).
2. Wash on the warmest/hottest water safe for the towel fabric.
3. Add your normal detergent amount (go light, not heroic).
4. Add 1/2 to 1 cup white distilled vinegar to the fabric softener dispenser or during the rinse cycle.
5. Select extra rinse if available.
6. Dry towels completely right away (more on drying strategy below).

Why it works (the short science-y version)

Vinegar’s mild acidity can help dissolve mineral deposits and loosen residue that holds onto odors. Once that coating is reduced,
detergent and water can do their job better, and smells have fewer places to hide.

Pro tips (so you don’t create a new problem)

• Don’t use vinegar every single wash forever. Some experts caution frequent vinegar use may wear rubber parts over time in certain machines. Use it as a reset, then switch to prevention habits.
• Don’t pour vinegar in with detergent in the main wash if your machine manual discourages itadding it to the rinse cycle is the common, gentler approach.
• Still smelly? Move on to Way 2 or Way 3 for a deeper deodorize.

Way 2: The Two-Cycle Baking Soda “Odor Neutralizer” (Simple, Effective, Very Pantry-Friendly)

Baking soda is a classic odor neutralizer. The most reliable approach for towels is a two-cycle method:
one cycle to loosen/strip residue (often vinegar), then a second cycle with baking soda to neutralize and finish the job.
Also: mixing baking soda and vinegar in the same moment is basically a middle-school volcanofun, fizzy, and not the best use of either ingredient.

Best for

• Towels with “I washed these twice and they’re still weird” energy
• Families with heavy towel use (kids, sports, beach, you know the vibe)
• Towels that smell okay wet but turn funky when warm (dryer heat can “wake up” trapped odors)

Step-by-step (two-cycle method)

1. Cycle 1 (strip): Run a hot/warm wash with towels + a small amount of detergent. If you suspect buildup, add vinegar in the rinse (Way 1).
2. Cycle 2 (neutralize): Run a second hot/warm wash with 1/2 cup baking soda and no fabric softener. You can skip detergent in this second cycle if the towels aren’t visibly dirtythis cycle is about odor neutralizing and rinsing out leftovers.
3. Finish with an extra rinse if you can.
4. Dry towels fully right away.

Why it works

Baking soda helps neutralize acidic odors and can boost rinsing by reducing some of the “cling” of residue in fibers.
When towels have a layered mix of body oils + leftover detergent + damp funk, this method often knocks the smell down fast.

Common mistakes to avoid

• Don’t overload the washer. Baking soda can’t outwork poor water circulation.
• Don’t “double detergent” in Cycle 2. More soap can mean more residue, which is the opposite of what we want.
• Don’t store towels even slightly damp. That’s how the stink gets its comeback tour.

Way 3: Oxygen Bleach (or Sanitizing Additive) Deep Clean (Heavy-Duty for Stubborn Mildew Smell)

If your towels have a true mildew smell that laughs at vinegar and baking soda, bring in the pros: oxygen bleach
(sometimes called “color-safe bleach”) or a laundry sanitizer used according to label instructions.
Oxygen bleach is popular because it works via oxygenation and is generally safer for colors than chlorine bleach.

Best for

• Deep, stubborn mildew odor
• Towels left damp in a pile for too long (we’ve all had a laundry-chair situation)
• Older towels that still have life left, but currently smell like they were raised by frogs

Option A: Oxygen bleach soak + wash (classic “rescue” method)

1. Fill a tub or bucket with the warmest water safe for the towels.
2. Add oxygen bleach per product directions (many recommend a measured scoop per gallon).
3. Soak towels for at least 1 hour; for tough odor, soak longer (some products suggest several hours).
4. Wash towels normally with detergent on warm/hot (no fabric softener).
5. Rinse well, then dry completely.

Option B: Laundry sanitizer in the rinse cycle

Sanitizing additives are designed to be added at the right stage (often the rinse). If you use one, follow the label timing carefully
so it’s actually doing the job and not being washed away too early.

What about chlorine bleach?

Chlorine bleach can disinfect and remove heavy mildew, but it’s not for every towel (especially colored towels) and must be used carefully.
If you use it, follow product directions precisely, use proper dilution, and never combine it with vinegar.

Drying strategy (the underrated hero)

• Dry immediately after washingdon’t let towels sit damp in the washer.
• If line drying is possible, sunlight can help (UV plus fresh air). For maximum softness, you can finish with a short tumble in the dryer.
• In the dryer, avoid over-drying, but make sure towels are fully dry before folding.

How to Keep Towels Fresh (So You Don’t Have to Keep Fixing This)

1) Hang towels like you mean it

After use, spread towels out so they dry fastno bunching on a hook like a damp burrito. Fast drying = less mildew growth.

2) Use less detergent than you think

Modern detergents are concentrated. Too much can cling to thick fabrics like towels, trapping oils and odors. If your towels feel coated,
cut the detergent down and use an extra rinse.

3) Skip fabric softener (towels don’t need it)

Fabric softener can reduce towel absorbency by coating fibers. If you want softness, try dryer balls and good rinsing instead.

4) Wash towels separately (usually)

Towels are heavier, lintier, and often need warmer water. Mixing them with clothes can lead to lint transfer and uneven cleaning/drying.
Separate loads keep everything cleaner and happier.

5) Clean the washer so it stops re-stinking your laundry

• Run a washer-clean cycle (or hot empty cycle) with a washer cleaner as directed.
• If you have a front loader, wipe the door gasket regularly and leave the door cracked open after use so the interior can dry.
• Remove loads promptly when the cycle ends.

When to Replace Towels Instead of Rescuing Them

If you’ve tried a deep clean (Way 3), your washer is clean, and the towels still smell musty as soon as they get warm or damp,
the odor may be embedded beyond what a normal home wash can fix. Also replace towels that have visible mold that won’t lift,
or towels that have lost absorbency and feel permanently coated.

Extra: of Real-World Experiences (So You Feel Less Alone)

Let’s talk about the part nobody brags about: the moment you realize your “fresh” towel is not fresh. It’s a universal experience,
like stepping on a LEGOexcept this time your nose is the one in pain.

Experience #1: The “I Forgot the Laundry Overnight” Surprise

A super common scenario: you run a load of towels, life happens, and the washer becomes a temporary towel hotel… for about 12 hours.
When you finally remember, the towels smell like a damp cave. The first instinct is to rewash with extra detergent.
Unfortunately, that often makes things worse because you’re layering new soap on top of the residue already clinging to the fibers.
The fix that tends to work is the reset approach: a hot wash with vinegar in the rinse, followed by a second cycle with baking soda.
The “two-step” feels annoyingly logical, but it’s the difference between masking and actually removing the gunk that feeds the odor.

Experience #2: The “Softener Made My Towels Weird” Era

Plenty of households go through a fabric-softener phase because soft towels sound like a good idea (and the bottle smells like a tropical vacation).
Then one day you notice the towels don’t absorb water welland they develop a faint, persistent funk that shows up the second they get damp.
That’s often the coating problem: softener and residue make towels less breathable and less rinseable.
People usually get their towels back by stopping softener, using less detergent, and doing one deep clean with vinegar and baking soda
(separate cycles). It’s also when dryer balls suddenly become the unsung heroes of laundry day.

Experience #3: The “Gym Towel in the Trunk” Plot Twist

A towel that lived in a gym bag or car trunk for a few days is basically a science experiment with feelings.
These are the cases where oxygen bleach shines. A soak (not just a wash) gives the cleaner time to work through thick fibers.
After soaking, washing hot (if the label allows) and drying completely usually removes the “I have seen things” smell.
Bonus lesson: if you must store an emergency towel in a car, store it bone-dry in a breathable bag,
and swap it out periodically like you’re rotating pantry stock.

Experience #4: The “My Washer Is the Problem, Isn’t It?” Revelation

Sometimes every load smells off, not just towels. That’s when people discover the washer gasket has been quietly collecting lint,
residue, and moisture like it’s building a tiny, gross terrarium. Once the gasket is wiped down, the detergent drawer is rinsed,
and a washer-clean cycle is run, towels suddenly stop coming out “pre-mildewed.”
It’s not glamorous maintenance, but it’s wildly satisfyinglike fixing a squeaky door and feeling like a home improvement wizard.

If you recognize yourself in any of these stories, congrats: you are a normal human with laundry responsibilities.
The solution isn’t perfectionit’s a solid reset method plus a few habits that keep towels dry, rinseable, and actually clean.

Wrap-Up

To remove mildew smell from towels, you don’t need stronger perfumeyou need to remove the residue and stop the damp-time cycle.
Start with a vinegar rinse reset, follow with a baking soda neutralizing wash when needed, and bring in oxygen bleach or a sanitizer
for stubborn, deep-set odor. Then lock in the win by drying towels fast, using less detergent, skipping softener, and keeping your washer clean.
Your towels will go back to smelling like nothingwhich, for towels, is the highest compliment.
