Why Your Towels Still Smell After Washing

Whether your towels smell musty, sour, or just aren't as fresh as they should be, you're not alone. Even freshly washed towels can develop lingering odors. The good news is that the towel usually isn't the problem. More often, odors are caused by detergent residue, trapped moisture, hard water minerals, or washing habits that prevent towels from getting truly clean.

Here are five common reasons your towels may still smell after washing and simple ways to help keep them smelling fresh.

1. Using Too Much Detergent

More detergent doesn't always mean cleaner laundry. Excess detergent can leave behind residue that traps bacteria and odors in the fabric.

Tip: Measure your detergent carefully and avoid overfilling the dispenser. Using the right amount of a quality detergent is often more effective than using too much. Our Plant-Based Liquid Laundry Detergent cleans effectively using just 1 tablespoon per load, while our Mineral-Based Powder Laundry Detergent uses only 1–2 teaspoons per load. Explore both to see which works best for your laundry routine.

2. Towels Stay Damp Too Long

Leaving wet towels in the washer or piled on the floor creates the perfect environment for odor-causing bacteria.

Tip: Move towels to the dryer promptly and hang them so they can dry completely between uses.

3. Hard Water Minerals

Minerals in hard water can build up in towel fibers, making them feel stiff and preventing detergent from cleaning effectively.

Tip: If you have hard water, consider using a laundry booster to help reduce mineral buildup and improve cleaning performance. Our unscented Oxygen Power Booster helps support a deeper clean, while our scented Laundry Booster provides the same mineral-based cleaning support with the added benefit of long-lasting fragrance. Both pair well with either of our laundry detergents.

4. Your Washing Machine Needs Cleaning

Even the best detergent can't fully clean towels if your washing machine has built-up residue, detergent film, or mildew. Over time, that buildup can transfer unwanted odors back into your laundry.

Tip: Clean your washing machine regularly according to the manufacturer's instructions and leave the door or lid open after each load so the inside can dry completely.

5. Overloading the Washer

Packing too many towels into one load prevents water and detergent from circulating properly. When towels can't move freely, they may not rinse clean, leaving behind residue and odors.

Tip: Wash towels in loads that allow plenty of room for water and detergent to circulate so every towel gets thoroughly cleaned and rinsed.
