You probably don’t wash your bath towels as often as you should. According to a University of Arizona environmental health professor, towels used after a bath or shower could be used up to three times if they’re hung to dry after each use.
Kelly A. Reynolds explained to BuzzFeed Life that dead skin cells end up on the towel after each time it’s used.
“Bacteria and mold will begin to accumulate, but growth will be slowed as the towel dries,” she told BuzzFeed.
Reynolds said that wash cloths should be washed after every time you use them. Since they become heavily soiled and wet during use, they take a longer time to dry. This can cause bacteria and mold to grow to “unacceptable levels.”
She also suggests washing kitchen cloths in bleach after every use; food and other particles that end up on them mean a higher chance of germs and bacteria will grow.
