How often do you wash your towels? According to one microbiologist, it probably isn’t enough.
Speaking to Business Insider, Philip Tierno, a microbiologist at the New York University School of Medicine said: “A damp towel is growing.”
Damp towels in the bathroom are the perfect breeding ground for bacteria.
As a result, Tierno says you should send your towel to the wash after three uses. Of course, this only applies if your towel has dried completely between each use.
Carolyn Forte, director of the Cleaning Lab at the Good Housekeeping Institute agrees.
"It's a matter of personal preference, but washing them after every use is a bit excessive," she says. "If you hang them on a towel bar and allow them to dry well after each use, bath towels can easily be used three times or even more before you toss them in the laundry. Washing and drying towels too often will make them wear out faster, and it's just a waste of time and energy."
Another indicator that your towel has seen better days is its smell.
Tierno says, "Wherever there is an odour, there are microbes growing, so it should be washed."
