How To Kill Bacteria On Towels

How often do you wash your bath towels? A common practice is once a week but it is obviously not enough. If you want to be sure there is no bacteria on your towel, you should dry it in direct sunlight as the sun rays sterilize it, or get a clean towel every time you reach for it.

Another way how to kill bacteria on towels is sterilizing them with hot temperature and UV light in a hot towel warmer cabinet. It is a very useful help in the fight against bacteria.

Why You Should Kill Bacteria on Towels

Bacteria can make the towels smell musty and sour. The mildew smell is a sign that a bacteria colony is breeding and growing. All it takes is a towel put away wet leaving it bunched up in a warm room.

Talking about damp, it’s not only bacteria. There is also mold and yeast on them. It sounds disgusting, doesn’t it? And when you think about it, they can also harm your skin.

How? Rubbing down with a dirty towel, and you could be at risk for infection. “When you use a towel vigorously, you scratch your skin,” says Dr. Charles Gerba, a microbiology professor at the University of Arizona. Small breaks occur in your skin, but they are too small to get noticed, and these break enable bacteria to get in your body.

So if you are acne-prone, you should get a clean and sterile towel every time.

Bacterial Contamination After One Day

Results of a test made by Dr. Oz and NSF International, an independent organization that checks product safety, proved that. They tested 31 towels that had been used for one day, 7 days or 14 days.

Significant amounts of bacteria were present on all of the towels tested, including those used for only one day. There were also yeast microbes present on more than half of the towels. Mold was present on nearly half of the towels, and some even held significant amounts of E. coli.

If you use your towel for hands and face, it could cause serious problems on your skin. I wouldn’t like to rub my face with a towel that has bacteria, mold and yeast on.

Even the towels used for only one day were seriously contaminated. Results of the test have shown that the amount of E. coli was ten times greater on towels used by men for two weeks. Yeast was hundred times greater on towels used by women for one day.

The results show we should change our towels at least or twice a week.

How Can You Sanitize Towels?

Obviously, washing them. Hot temperatures can kill most germs – usually at least 140°F (60°C). A temperature of 155°F (68°C) is safer, though. Cotton towels can be washed at such a high temperature but it’s too hot for linen towels.

„Hot temperatures can kill most germs — usually at least 140 degrees Fahrenheit.“

Can You Reuse a Bath Towel?

It is safe to reuse a bath towel a few times between washes. However, you should always hang them and let them dry because when they are damp, they can quickly become home to unwanted microorganisms.

I’ve done a research regarding recommendations of various experts and the most common time they advice to wash bath towels is every two to three uses. However, for the face I wouldn’t recommend to use the same towel more than once.

It is easy to get infection onto your face. More so if you use a facial massager or derma roller where your skin is supposed to be perfectly clean and sterile.

How To Kill Bacteria While Washing

Washing does not automatically mean all harmful microorganisms are killed in the process. It is the drying that counts. The heat of a tumble dryer ranges from 130 to 150° F so the unwanted bacteria and fungus are killed in the dryer on high heat.

Hanging the towels outdoors in direct sunlight for a couple of hours is best, if you have a balcony or garden. Have you noticed how nice do the towels smell when they dry in fresh air? The sun’s ultraviolet rays act as a natural disinfectant, they are as effective as bleach or clorox.

Drying the towels in sunshine and fresh air is perfect but what about in winter?

Sterilization: Hot Towel Warmer Cabinet

If you don’t sterilize your towels at least once in a while, they can become smelly, indicating bacteria or germ growth. It is a big difference to wrap yourself in a fresh and nice smelling towel or a stinky one, isn’t it?

I haven’t found any case of someone getting sick from using a towel full of bacteria or mold. However, the risk exists so it’s better to be safe than sorry.

Hot towel warmer cabinet is a great invention I found only recently. These practical cabinets sterilize all towels with ultra light so you can be sure the towel you rub your face with is perfectly clean.

They vary in size and features, the smallest ones (8L) are size of a microwave and fit well even in the smallest bathrooms.

And another benefit apart from sanitizing your towels is the nice feeling of a hot towel on your skin.


The best way to kill bacteria on towels is to wash them at high temperature and let them dry in direct sunlight.

Hang up your towels after each use to help them dry properly and prevent odor.

Sterilizing damp towels in a hot towel warmer cabinet provides cosy-warm towels free of bacteria for every day use. Having this useful assistant in your bathroom, you can reuse the towels more times without worrying about bacteria and viruses.

  1. Great article. It is really informative. You know many people today suffer from skin problems because of not paying attention to the cleanliness of the towels they use. The information on how to properly clean our towels as presented in this article can help people avoid various skin problems. 

     I agree with you that towels specifically for the face should only be used once. A friend of mine was having severe facial rashes because of using towels several times without washing.


    1. It’s true and I’m always very careful with towels on my face, rather than using a towel that was used several times I would let my face dry on its own. Nevertheless, it is a nice feeling to have a warm towel (and even a sterilized one) ready for use after a wash or a shower, especially in winter.

  2. This is a very important topic. As generally known having a direct sunlight in a place like Germany in winter is not possible so I usually wash towels with an anti-bacterial detergent before drying on the heater. However, your recommendation of sterilizing damp towels in a hot towel warmer cabinet for every day use is very good.

    1. I think there are many people unaware of the fact how many bacteria a towel that still seems pretty clean after a few uses can hold. Yeah, the biggest problem is winter, you can’t put the towels outside and they get damp easily.
