Remove Mildew Smell from Towels with Vinegar
That musty, damp smell coming from your towels isn't just unpleasant—it's mildew. Mildew develops when bacteria and fungi grow on damp fabric that hasn't dried properly, and it can make even freshly washed towels smell stale. The good news is that you can eliminate mildew smell from towels using two simple household ingredients: vinegar and baking soda.
This guide will show you exactly how to remove mildew smell from towels, why this method works, and how to prevent that musty odor from returning.
Why Do Towels Smell Like Mildew?
Before learning how to fix the problem, it helps to understand what causes that mildew smell in the first place. Towels develop a musty odor when they remain damp for extended periods. This creates an ideal environment for mildew-causing bacteria and fungi to multiply within the fabric fibers.
Common causes of mildew smell in towels include:
Leaving wet towels bunched up after use
Storing towels in humid bathrooms without proper ventilation
Not drying towels completely before folding
Using too much detergent, which leaves residue that traps moisture
Overloading the washing machine so towels don't rinse properly
Standard laundry detergent often fails to eliminate mildew odor because it doesn't kill the bacteria embedded deep within the towel fibers. This is where vinegar and baking soda become essential.
How to Remove Mildew Smell from Towels with Vinegar and Baking Soda
This two-cycle washing method is the most effective way to strip mildew odor from towels completely. The key is using vinegar and baking soda in separate wash cycles—never together in the same load.
What You'll Need
White distilled vinegar (1-2 cups)
Baking soda (½ cup)
Hot water
Avoid using apple cider or other flavored vinegars, as white distilled vinegar works best and won't leave any residue or discoloration.
Step-by-Step Instructions
Cycle One: The Vinegar Wash
Place your mildew-smelling towels in the washing machine without overcrowding
Add one cup of white distilled vinegar directly to the drum (not the detergent dispenser)
Do not add any detergent or fabric softener during this cycle
Run a complete wash cycle using the hottest water setting your towels can handle
The vinegar's acidity breaks down the mildew-causing bacteria and dissolves the detergent buildup that traps odors in the fabric. Hot water helps the vinegar penetrate deep into the towel fibers where mildew colonies hide.
Cycle Two: The Baking Soda Wash
Without removing the towels, add half a cup of baking soda directly to the drum
Again, do not add detergent or fabric softener
Run another complete wash cycle on hot
Baking soda neutralizes any remaining odors and absorbs residual moisture that could encourage future mildew growth. Its mild abrasive properties also help scrub away any remaining bacteria from the fabric fibers.
Drying Your Towels
Immediately after the wash cycles complete, either tumble dry on high heat or hang towels outside in direct sunlight. Never leave wet towels sitting in the washer, as this is exactly how mildew develops in the first place. Sunlight provides natural antibacterial properties and helps eliminate any lingering musty smell.
Alternative Method: The Overnight Vinegar Soak
For towels with stubborn mildew odor that won't respond to the standard two-cycle method, try an extended vinegar soak.
Fill a bathtub or large bucket with hot water
Add two cups of white distilled vinegar
Submerge your towels completely
Let them soak for at least four hours, or overnight for severe cases
After soaking, wring out the towels and wash them normally with your regular detergent
Follow with the baking soda cycle described above
Dry immediately
The extended contact time allows the vinegar to fully penetrate the fabric and break down even deeply embedded mildew.
Why Vinegar and Baking Soda Work Better Than Detergent
Regular laundry detergent is designed to lift dirt and oils from fabric, but it doesn't effectively kill mildew-causing bacteria. In fact, using too much detergent can make the problem worse by leaving residue that traps moisture and creates an environment where bacteria thrive.
Vinegar's acetic acid has natural antimicrobial properties that kill bacteria, mold, and mildew on contact. It also dissolves mineral deposits from hard water and strips away built-up detergent residue.
Baking soda's alkaline nature neutralizes acidic odor compounds while its mild abrasiveness helps physically remove contaminants from fabric fibers.
Together, these two ingredients address both the cause (bacteria and mildew) and the symptom (the smell) without leaving behind any residue that could cause future problems.
How to Prevent Mildew Smell in Towels
Once you've eliminated the mildew smell, take these steps to prevent it from returning.
Dry Towels Properly After Each Use
Hang towels spread out on a towel bar rather than bunched on a hook. Ensure good air circulation in your bathroom by running the exhaust fan during and after showers. If your bathroom lacks ventilation, consider moving towels to a drier location between uses.
Wash Towels Regularly
Wash bath towels after three to four uses. Waiting longer allows bacteria and body oils to accumulate, creating conditions that promote mildew growth. Use hot water and avoid overloading the machine so towels can move freely and rinse thoroughly.
Use Less Detergent
More detergent doesn't mean cleaner towels. Excess detergent leaves residue that builds up over time, reducing absorbency and creating a breeding ground for bacteria. Use the amount recommended on the package, or slightly less for high-efficiency machines.
Skip the Fabric Softener
Fabric softener coats towel fibers with a waxy residue that reduces absorbency and traps moisture. If you want softer towels, add half a cup of white vinegar to the rinse cycle instead—it softens naturally without leaving residue.
Dry Completely Before Storing
Never fold and store towels that feel even slightly damp. Either extend the drying time or hang them to finish air drying before putting them away. Storing damp towels in a closed linen closet virtually guarantees mildew development.
When to Replace Your Towels
Sometimes mildew damage is too severe to reverse. Consider replacing your towels if:
If your towels are beyond saving, consider replacing them with wholesale bath towels — buying in bulk keeps per-unit costs low for homes and businesses alike.
The mildew smell persists after multiple treatments with vinegar and baking soda
You notice visible discoloration or dark spots that don't wash out
The towels feel stiff or have lost their absorbency
The fabric has become thin or started developing holes
With proper care, quality towels should last two to three years before needing replacement. Regular maintenance washes with vinegar every few weeks can significantly extend their lifespan.
Frequently Asked Questions
Can I use vinegar and baking soda on colored towels?
Yes, white distilled vinegar is safe for colored towels and won't cause fading. However, always use cold or warm water rather than hot for dark-colored towels to preserve the dye.
Why shouldn't I mix vinegar and baking soda together?
When vinegar (an acid) and baking soda (a base) combine, they neutralize each other in a fizzy reaction that produces water and carbon dioxide. This means neither ingredient retains its cleaning power. Using them in separate cycles allows each to work at full strength.
How often should I do a maintenance wash with vinegar?
For most households, running a vinegar-only wash cycle once every two to four weeks keeps towels fresh and prevents mildew buildup. If you live in a humid climate or your towels get heavy use, consider doing it more frequently.
Can I use apple cider vinegar instead of white vinegar?
White distilled vinegar is preferred because it's colorless and won't stain fabric. Apple cider vinegar can leave a slight tint on light-colored towels and may leave behind a faint smell.
Will my towels smell like vinegar after washing?
No. The vinegar smell dissipates completely during the rinse cycle and drying process. Your towels will smell fresh and clean with no vinegar odor.
Final Thoughts
Removing mildew smell from towels doesn't require expensive products or professional cleaning. With white vinegar, baking soda, and the two-cycle washing method outlined above, you can restore even the mustiest towels to fresh, clean condition.
For hospitality businesses that need to maintain fresh linens at scale, stocking up on hotel towels in bulk ensures you always have clean replacements on rotation.
The key to success is addressing both the bacteria causing the smell and the conditions that allowed mildew to develop. By following the prevention tips in this guide, you can keep your towels smelling fresh for years to come.

```How to Soak Towels in Vinegar Overnight for Deep Odor Removal
For towels with stubborn mildew smells or years of built-up detergent residue, a quick wash cycle may not be enough. An overnight vinegar soak gives the acetic acid in white vinegar the time it needs to fully penetrate fabric fibers, dissolve mineral deposits, break down soap buildup, and kill the bacteria responsible for that musty odor.
Step-by-Step Overnight Vinegar Soak
- Fill a basin or bathtub with hot water. Use the hottest water safe for your towel fabric—check the care label. Hot water helps activate the vinegar and loosen residue.
- Add 1 to 2 cups of distilled white vinegar. Stir to combine. For a single towel, 1 cup is sufficient; scale up for a full load.
- Submerge the towels fully. Press them down so every part of the fabric is saturated with the vinegar solution.
- Soak for 8 to 12 hours (overnight). Cover the basin loosely and let the vinegar work undisturbed. This extended contact time is what separates an overnight soak from a standard wash cycle.
- Wash as normal in the morning. Transfer towels directly to your washing machine and run a hot cycle with your regular detergent. No need to rinse the vinegar out first—it will wash away cleanly.
- Dry thoroughly. Tumble dry on medium-high heat or line dry in direct sunlight. Never fold or store towels while still damp.
For the worst cases of mildew odor, follow up the vinegar soak cycle with a second wash using half a cup of baking soda. The two treatments work on different levels—vinegar strips bacteria and mineral buildup while baking soda neutralizes any remaining odor molecules.
Frequently Asked Questions
Can I soak towels in vinegar overnight without damaging them?
Yes. Distilled white vinegar is safe for cotton, microfiber, and most common towel fabrics when diluted in water. Avoid soaking towels with delicate embroidery or dry-clean-only labels. An overnight soak in a diluted vinegar solution will not weaken fibers or fade colors.
How much vinegar do I need to soak towels overnight?
Use 1 cup of distilled white vinegar per gallon of water. For a full bathtub soak covering several towels, 2 cups is typically enough. Avoid using more than this—higher concentrations don't improve results and can leave a faint vinegar smell after drying.
Will my towels smell like vinegar after soaking?
No. The vinegar scent dissipates completely during the wash and dry cycle. If you can still detect a faint smell after drying, run the towels through one additional rinse cycle—they'll come out odor-free.

```Washing Towels with Vinegar and Baking Soda: The Complete Method
Washing towels with vinegar and baking soda is the most effective way to deep-clean towels, strip detergent buildup, and restore absorbency—all without harsh chemicals. Whether your towels smell musty or have gone stiff over time, this two-ingredient method resets them to like-new condition.
Why Wash Towels with Vinegar and Baking Soda?
Regular detergent alone can leave behind residue that builds up in towel fibers over dozens of washes. This residue traps moisture, reduces absorbency, and creates the conditions mildew needs to thrive. White vinegar cuts through that buildup with its natural acetic acid, while baking soda neutralizes odors and softens fabric at the fiber level. Together—used in separate cycles—they outperform any commercial fabric softener or odor eliminator.
Step-by-Step: How to Wash Towels with Vinegar and Baking Soda
- First cycle – Vinegar: Load your towels into the washing machine. Add 1–2 cups of white distilled vinegar directly to the drum or detergent compartment. Select the hottest water setting safe for your towels and run a full wash cycle. Do not add detergent.
- Second cycle – Baking soda: Without removing the towels, add ½ cup of baking soda to the drum. Run a second full hot wash cycle. This step lifts any remaining odor and softens the fibers loosened by the vinegar.
- Dry thoroughly: Transfer towels to the dryer immediately and dry on high heat until completely dry. Leaving damp towels sitting is the fastest way to reintroduce mildew odor.
How Often Should You Wash Towels This Way?
For everyday maintenance, washing towels with white vinegar once a month prevents buildup before it starts. If your towels are already stiff or smelly, run the full two-cycle treatment immediately, then move to a monthly vinegar-only maintenance wash. With consistent care, towels stay soft, absorbent, and odor-free for years longer than with detergent alone.
