You should swap your washcloth for a clean one after every one to two uses, and at minimum several times per week. Washcloths pick up dead skin cells, oil, and moisture each time you use them, creating ideal conditions for bacteria to multiply between showers. Because they’re smaller and thicker than bath towels, they stay damp longer and accumulate germs faster.
Why Washcloths Get Dirty So Fast
Every time you scrub your face or body with a washcloth, you’re transferring skin cells, natural oils, and bacteria onto the fabric. The cloth then sits in your warm, humid bathroom, which is essentially an incubator. A damp washcloth bunched up on the edge of the tub can stay wet for hours, giving microbes plenty of time to feed and reproduce.
Research published in the NIH’s PubMed Central analyzed towels and cloths used daily and found that bacteria from multiple classes colonize the fabric quickly. The dominant organisms weren’t the familiar skin bacteria you’d expect (those were detected at very low levels). Instead, environmental bacteria thrived, including types that form biofilms, the slimy, structured colonies that cling to fibers and resist rinsing. Over time, those biofilms build up and contribute to that musty smell and dingy appearance that tells you a cloth has been used too long.
Face vs. Body: Different Rules
For your face, the simplest approach may be to skip the washcloth entirely. The American Academy of Dermatology recommends using only your fingertips to wash your face, noting that washcloths, mesh sponges, and other tools can irritate facial skin. If you prefer using a cloth on your face, use a fresh one every single time. Facial skin is thinner and more reactive, and a cloth that’s been sitting damp for even a day can introduce enough bacteria to trigger breakouts or irritation.
For your body, replacing the cloth every one to two showers is a reasonable target. Cleveland Clinic guidance suggests changing washcloths at least a couple times a week as a minimum, but daily is better if you can manage the laundry. If you exercise heavily, use the cloth on areas prone to friction or sweating, or have any open cuts or razor bumps, a fresh cloth every time is worth the effort.
Skin Infections From Dirty Washcloths
Reusing a contaminated washcloth isn’t just unpleasant. It can cause real skin problems. Folliculitis, those itchy, pus-filled bumps around hair follicles, is one of the most common results. It’s typically caused by staph bacteria, which can transfer from a dirty cloth to small nicks or open pores. The Mayo Clinic specifically lists using a clean washcloth every time as a prevention strategy for folliculitis and recommends never sharing washcloths or towels with others.
People with eczema, acne, or compromised immune systems are at higher risk. Even if you don’t develop a visible infection, repeatedly dragging a bacteria-laden cloth across your skin can worsen inflammation and slow the healing of existing blemishes or irritation.
How to Keep Washcloths Cleaner Between Uses
If you do reuse a washcloth for a second shower, how you store it matters. Hang it spread flat on a hook or towel bar where air circulates freely. A washcloth left crumpled on the shower floor or draped over the faucet stays damp far longer, accelerating bacterial growth. If your bathroom has poor ventilation, no window, and no exhaust fan, the cloth may never fully dry between uses, which means you should grab a fresh one every time regardless.
Rinsing the cloth thoroughly after each use and wringing it out helps remove some surface bacteria and speeds drying. But rinsing alone doesn’t sanitize. Only laundering with hot water and detergent actually kills the organisms that colonize the fibers.
Cotton vs. Microfiber Cloths
The fabric your washcloth is made from affects how quickly bacteria accumulate. Standard cotton washcloths are absorbent and soft, but they hold moisture for a long time. That lingering dampness is exactly what bacteria need to thrive. Microfiber dries significantly faster than cotton, which limits the window for bacterial growth between uses. Research from the Western States Pediatric Environmental Health Specialty Unit found that microfiber’s quick-drying properties make it harder for bacteria to establish themselves compared to cotton.
That said, microfiber’s textured surface can be too rough for sensitive or acne-prone facial skin. For body washing, a microfiber cloth that dries quickly between uses can be a practical choice, especially if you tend to stretch washcloth use to two or three days. Bamboo-blend cloths fall somewhere in between: they dry faster than pure cotton but not as fast as microfiber.
A Simple Washcloth Rotation
The easiest way to stay on top of washcloth hygiene is to keep a stack of seven to ten clean cloths in your bathroom and toss each one into the hamper after one or two uses. Washcloths are small, so they add almost nothing to your laundry load. Wash them in warm or hot water with your regular detergent, and dry them completely in the dryer or in direct sunlight, which adds a mild natural sanitizing effect.
If your washcloths start to smell musty even after washing, that’s a sign biofilm has built up in the fibers. At that point, soaking them in a diluted white vinegar solution before laundering can help break down the buildup. Cloths that still smell after that treatment have reached the end of their useful life and should be replaced entirely.
