According to the Cleaning Institute, towels should be washed after every third use, assuming that the towel dries completely between uses. However, some experts recommend washing towels after every use to ensure cleanliness. It is also recommended to wash washcloths after every use. If you notice an unpleasant smell or persistent dampness, you should wash your towels sooner. Here are some tips for good towel care:

• Wash after every third use, or sooner if you notice an unpleasant smell or persistent dampness. Keep this in mind for hand towels as well, which tend to get used more frequently than bath towels.
• Hang your towel somewhere ventilated and let it dry completely between each use to prevent the growth of bacteria.
• Replace your towels every few years.

It is important to note that towels absorb a lot of water and remain damp for hours, which is the perfect breeding ground for unwanted germs. Therefore, washing towels frequently is necessary to remove any germs that are starting to accumulate.
