TL;DR: It’s likely you’re washing your towels wrong. Wash towels every 3-4 uses (gym towels after every use). Use half the detergent you think you need. Skip the fabric softener – it coats fibers and kills absorbency. Wash on warm (occasionally hot), tumble dry on medium, and never leave wet towels bunched in the machine. White vinegar once a month strips buildup.
Here’s a question that starts more arguments than it should: how often do you wash your towels? If the answer is “when they start to smell,” you’re not alone — but you’re also creating a situation that would make a microbiologist wince.
The truth is, most of us have been washing towels wrong for years. Not catastrophically wrong, but wrong enough that our towels get stiff, lose their fluff, and develop that musty smell no amount of Febreze can actually fix. The good news? The fixes are simple, and they don’t require buying anything fancy.
Mistake #1: You’re Not Washing Towels Often Enough
According to cleaning experts at Good Housekeeping, bath towels should be washed every 3-4 uses. That’s roughly twice a week if you shower daily. Gym towels? After every single use … no exceptions. Hand towels in the bathroom should be swapped out at least once a week, and more often if you have kids or pets in the house.
The reason is straightforward: towels collect dead skin cells, body oils, and moisture every time you use them. In a warm, humid bathroom, those become a breeding ground for bacteria and mildew. By use number five, your “clean” towel is working against you.
Mistake #2: You’re Washing Your Towels Wrong Using Too Much Detergent
This one surprises people. More soap does not mean cleaner towels … it means towels coated in detergent residue that traps odors and makes fibers feel waxy. Consumer Reports recommends using about half the amount listed on your detergent bottle for a load of towels.
If your towels feel crunchy or don’t absorb water well after washing, excess detergent buildup is almost certainly the culprit. Run them through a cycle with just hot water and a cup of white vinegar to strip the residue, then go lighter on soap going forward.
Mistake #3: You’re Using Fabric Softener
Fabric softener makes everything feel silky, which sounds great … until you realize it does that by coating fibers with a thin layer of chemicals. On cotton towels, that coating reduces absorbency over time. Your towels feel soft coming out of the dryer but push water around instead of soaking it up.
The better alternative: wool dryer balls. They physically separate towel fibers during the drying cycle, which creates softness through fluffing rather than coating. You can find them at most grocery stores or order a set online for under $15.
Mistake #4: You’re Drying Towels on High Heat
Cranking the dryer to high seems logical: towels are thick, they take forever, you want them done. But high heat damages cotton fibers over time, making towels thin and scratchy after just a few months. Medium heat takes a little longer but keeps the fibers intact.
If you want that fresh-from-the-store fluffiness, try the tennis ball trick: toss two clean tennis balls in the dryer with your towels. They bounce around and keep the towels from clumping, which helps them dry evenly and come out softer.
Mistake #5: You’re Leaving Wet Towels Sitting in the Washer
We’ve all done it … started a load of towels, got distracted, and came back three hours later to that unmistakable damp, musty smell. Once mildew sets in, you either need to re-wash (with vinegar and baking soda) or accept towels that smell like a forgotten gym bag!
Set a timer on your phone. It’s a tiny habit that saves a lot of re-washing.
The Monthly Reset: Vinegar Wash
Once a month, run your towels through a hot cycle with one cup of white vinegar and no detergent. This strips accumulated residue, kills odor-causing bacteria, and restores absorbency. Follow it with a normal wash. It’s the single best maintenance habit you can adopt for your towels.
Or … just let someone else handle it.
Look, towel care isn’t complicated, but it does require attention. If keeping track of wash frequency and vinegar cycles and dryer temperatures sounds like one more thing on a list that’s already too long, that’s fair. SmartSpun Laundry handles all of this for you, with professional-grade equipment and processes that keep your towels soft, fresh, and actually absorbent. One less thing to think about.

How often should you wash bath towels?
Every 3-4 uses, according to experts at Good Housekeeping. Gym towels should be washed after every use, and hand towels at least once a week – more often if you have kids or pets.
Why do my towels smell musty even after washing?
Usually it’s one of three things: too much detergent leaving residue, leaving wet towels sitting in the washer too long, or not washing often enough. A vinegar wash cycle (one cup of white vinegar, no detergent, hot water) will strip buildup and eliminate odors.
Should you use fabric softener on towels?
No. Fabric softener coats cotton fibers with a chemical layer that reduces absorbency over time. Use wool dryer balls instead for softness without the coating.
What temperature should you wash towels at?
Warm water (around 105°F / 40°C) is best for most towels. Hot water can be used occasionally for sanitizing but damages fibers with repeated use. Always dry on medium heat, not high.
