How to Get Odor Out of Towels: Easy DIY Methods That Work

You wash your towels regularly, yet they still come out smelling musty the moment they get damp, that sour, mildewy odor that no amount of fabric softener seems to fix. Knowing how to get odor out of towels starts with understanding why they smell in the first place: trapped detergent residue, fabric softener buildup, and lingering moisture create a breeding ground for the bacteria and mildew that cause the stink. The fix is not more product, it is the right products, the right water temperature, and making sure the towels actually dry all the way.

Why Towels Get Smelly

Towels are thick and absorbent, which is exactly the problem. Over time they accumulate residue from too much detergent and fabric softener, that buildup coats the fibers, traps moisture and bacteria, and makes towels both less absorbent and more prone to odor. Add a damp towel left in a heap or a wet load forgotten in the washer, and mildew takes hold fast. The smell you notice when a towel gets wet is bacteria reactivating. Beating it means stripping the buildup and denying mildew the moisture it needs.

The Vinegar and Hot Water Wash

The single most effective fix is a hot wash with white vinegar, no detergent. Vinegar’s acidity cuts through residue and kills odor-causing bacteria:

1. Load the smelly towels into the washer with nothing else
2. Add one cup of plain white vinegar to the load (in the drum or the dispenser)
3. Run the hottest water cycle the towels can safely handle
4. Do not add detergent or fabric softener, this is a stripping wash

Hot water helps kill bacteria and dissolve buildup, while the vinegar deodorizes. Check your towel care label, but most cotton towels tolerate hot water well.

Follow With a Baking Soda Wash

For deeply set-in odors, follow the vinegar wash with a second cycle using baking soda. Run the towels again on hot with about a half cup to a cup of baking soda and, again, no detergent. Baking soda neutralizes odors and further lifts residue. The one-two punch, vinegar first, baking soda second, is a classic, chemical-free reset that revives towels most people would have thrown out. Do not combine vinegar and baking soda in the same load, they neutralize each other; run them as separate cycles.

Use Less Detergent, Not More

It feels backward, but overdosing detergent is a leading cause of smelly towels. Excess suds do not fully rinse out, leaving residue that traps odor and bacteria. Going forward:

• Use less detergent than you think, often half the recommended amount is plenty
• Skip the fabric softener, it coats fibers, reduces absorbency, and contributes to buildup
• Try wool dryer balls instead of softener for fluffiness without the residue
• Run an extra rinse if your machine offers it, to flush out leftover soap

Less product, fully rinsed, keeps towels fresh far longer than piling on more.

Dry Towels Completely and Promptly

Drying is where most odor problems are won or lost. Mildew needs moisture, so the goal is to get towels bone-dry, fast. Move towels from the washer to the dryer right away, do not let a damp load sit. Dry them on a setting hot enough to fully dry the fabric without scorching it, and make sure they come out completely dry, not slightly damp at the folds. If you line-dry, choose a sunny, breezy spot; sunlight has a natural deodorizing and sanitizing effect. A towel that never fully dries between uses is a towel that will always smell.

Daily Habits That Keep Odor Away

Once your towels are fresh again, a few simple habits prevent the smell from returning. Hang towels spread out to dry after each use rather than wadding them on a hook or the floor, spread fabric dries; bunched fabric stays damp. Don’t reuse a towel too many times before washing, and wash bath towels regularly. Never leave a wet load sitting in the washer, run it again if you forget. Keep the bathroom ventilated so towels can dry between uses.

Maintain Your Washing Machine, Too

Sometimes the towels are not the only culprit, the washer itself can harbor mildew and pass the smell to your laundry. Front-loaders especially trap moisture in the door gasket. Run a monthly cleaning cycle with hot water and vinegar (or a washer cleaner), wipe the gasket and detergent drawer, and leave the door ajar between loads so the drum dries out. A clean machine is essential to clean-smelling towels.

Stripping Towels for a Deep Reset

For towels that have years of buildup and smell musty no matter what you do, a laundry strip soak gives the deepest reset. Fill a tub or large basin with hot water and soak the towels for several hours, stirring occasionally; the hot water draws out residue you cannot see, and the water often turns surprisingly gray. Some people add a stripping mix to the soak, but plain hot water alone, followed by a normal wash with little or no detergent, removes a remarkable amount of trapped grime. Do this once or twice a year on towels that have gone stiff and smelly, and they will come back noticeably softer and fresher.

Choosing and Caring for New Towels

If towels are beyond saving, the right habits from day one keep replacements fresh longer. Wash brand-new towels before first use, often with a cup of vinegar, to remove the manufacturing finish that can repel water and trap odor. Avoid fabric softener on towels entirely from the start, since the coating that causes problems builds from the very first wash. Choose a sensible wash frequency, do not let towels go too long between washes, and always get them fully dry. Treating new towels well prevents the buildup cycle before it can begin.

The Bottom Line

The reliable answer to how to get odor out of towels is a hot vinegar wash followed by a baking soda wash to strip buildup and kill mildew, then a permanent switch to less detergent, no fabric softener, and complete, prompt drying. Add good hanging and washing habits and keep your machine clean, and your towels will stay fresh and absorbent instead of turning musty the moment they get wet.
