There’s nothing worse than stepping out of a refreshing shower and wrapping yourself in a towel that smells musty or damp. This unpleasant odor not only ruins the clean feeling but can also signal bacteria or mildew buildup in the fabric. The good news? You can banish that musty smell once and for all with one simple household ingredient and a few easy washing habits.

Why Towels Smell Musty

Towels are made to absorb moisture, but that same quality makes them prone to retaining dampness—especially in poorly ventilated bathrooms. When towels don’t dry completely between uses, they become the perfect breeding ground for mold and bacteria. The result is that distinct musty or “wet dog” smell that clings to the fabric even after washing.

Other common causes include:

• Leaving towels in the washer for too long after the cycle finishes.
• Folding and storing towels while still slightly damp.
• Using too much detergent or fabric softener, which leaves behind residues that trap odors.
• Low washing temperatures, which may fail to kill odor-causing bacteria.

The key to keeping your towels fresh is to make sure they dry completely and are washed in a way that deep-cleans the fibers rather than coating them.

How to Prevent Musty Towels

Prevention is always better than cure. To keep your towels fresh and soft, follow these simple habits:

1. Air them out after each use. Hang towels on a bar (not a hook) so they can spread out and dry fully.
2. Ensure proper ventilation. Keep your bathroom well-ventilated, or place towels near a window or fan to speed drying.
3. Never store damp towels. Make sure towels are completely dry before folding or putting them away.
4. Wash similar colors together. This preserves the vibrancy of your towels and prevents color transfer.
5. Choose the right wash cycle. A gentle cycle at 40°C (104°F) works well for most towels, with a spin speed around 800 rpm. Some cotton towels can tolerate 60°C (140°F)—always check the care label first.

Avoid overloading your washing machine, as towels need room to move around for an effective wash.

The One Ingredient That Eliminates Musty Odors

If your towels already smell bad, don’t rush to throw them out—there’s an easy fix. The secret is white vinegar (or apple cider vinegar), a natural deodorizer and fabric softener that neutralizes odors without harsh chemicals.

Vinegar works because it:

• Breaks down detergent and fabric softener residue trapped in towel fibers.

• Neutralizes bacteria and mold that cause foul smells.
• Softens the fabric naturally, keeping towels fluffy and absorbent.
• Prevents limescale buildup in your washing machine.

Here’s how to use it effectively.

Method 1: Vinegar Wash Cycle

1. Place your musty towels in the washing machine.
2. Select a pre-wash cycle or start your normal cycle.
3. As soon as the washer begins filling with water, pour one cup of white vinegar directly into the drum (not the detergent dispenser).
4. Let the cycle complete without adding detergent.
5. Once done, wash the towels again with your usual detergent to remove any remaining odor.

You’ll notice an immediate improvement—the towels come out clean, fresh, and soft.

Method 2: Vinegar Soak

If you prefer not to pour vinegar directly into your washing machine, you can soak the towels first:

1. Fill a large basin or tub with hot water.
2. Add one cup of white vinegar.
3. Submerge the musty towels completely and let them soak for at least an hour.
4. Wring them out gently, then wash as usual in the washing machine with a mild detergent.

This method gives the vinegar more time to break down bacteria and residue trapped deep in the fibers.

Why You Should Skip Fabric Softener

Many people use commercial fabric softeners to make towels smell nice and feel soft, but these products can actually make the problem worse over time. Softener leaves behind a waxy coating that traps detergent and moisture inside the fibers, reducing absorbency and creating the perfect conditions for odor buildup. Vinegar, by contrast, acts as a natural softener that leaves no residue and even helps descale your washing machine.

Drying Towels Properly

Even after washing, how you dry your towels matters. If freshly washed towels sit too long in the drum, the damp environment quickly reintroduces that musty smell.

Here’s the right way to dry them:

• Remove towels immediately after the wash cycle ends.
• Dry outdoors if possible, preferably on a breezy, sunny day.
• If drying indoors, use a well-ventilated space or a tumble dryer on a moderate setting.
• Make sure they are completely dry before folding—even a hint of moisture can restart the odor cycle.

The Long-Term Benefits of Vinegar

Using vinegar regularly in your laundry routine doesn’t just refresh towels—it also helps your washing machine stay in top shape. Its natural descaling action removes limescale and soap scum, improving the machine’s efficiency and longevity.

In short, vinegar is an affordable, eco-friendly, and powerful solution for tackling musty towels and maintaining freshness. By combining this simple ingredient with proper washing and drying habits, you can say goodbye to that unpleasant damp smell for good and enjoy towels that smell clean and feel luxuriously soft every time you use them.
