People regularly change and wash their clothes, but they often forget about the need to wash handkerchiefs, which are an integral part of daily life. Handkerchiefs are used to wipe sweat, when sneezing, or to wipe hands, regardless of whether the person is in an office, a student, or a traveler, as such accessories are often kept in pockets or bags.
The question arises as to how often a handkerchief used throughout the day should be washed. Many continue to use the handkerchief until visible stains appear or an unpleasant odor develops. However, the external cleanliness of the fabric does not guarantee the absence of dirt and bacteria on it. Therefore, maintaining the hygiene of the handkerchief should become part of daily routines.
How often should a handkerchief be washed?
If you use a cloth handkerchief daily, the optimal option is to wash it after every use, especially if you use it to clean your nose, during coughing or sneezing, or to wipe sweat. You should avoid reusing a used handkerchief the next day without washing it first.
Even if the handkerchief was only used to lightly wipe sweat, it needs to be washed regularly. Furthermore, if the handkerchief has come into contact with nasal discharge, sneezing, coughing, or is heavily soiled, it is better to replace it than reuse it. Therefore, it is recommended to have a spare handkerchief.
What did the study show?
In December 2025, a scientific paper titled 'Microbiological Testing of Handkerchiefs Used by Lower Elementary School Children' was published in the Journal of Home Economics of Japan. This study tested cotton handkerchiefs used by children in Japanese primary schools. Researchers provided the children with handkerchiefs for use during the summer and autumn of 2022 and checked for bacteria after one day of use.
The testing revealed microorganisms associated with various types of bacteria and fungi. To prevent infections, researchers advised children to wipe their hands with a clean, freshly washed handkerchief after washing hands and before eating at school. Nevertheless, since this study was conducted on children's handkerchiefs, one cannot conclude that any handkerchief causes illness. However, it is evident that even visually clean fabric can contain bacteria.
What is the correct way to wash a handkerchief?
To maintain the cleanliness of the handkerchief, you can follow several simple rules: first, wash it using soap or detergent, choosing a suitable fabric powder, and thoroughly removing all stains. It is important not to leave a used handkerchief wet in a bag or pocket for long. After washing, the handkerchief should be dried in a clean place, ensuring it is completely dry before the next use.
Moreover, the handkerchief is a personal item, so you should refrain from sharing it with family members or friends. It is also important to always carry an extra clean handkerchief for those who go out often, to replace a dirty one.
According to data from the Centers for Disease Control and Prevention (CDC) of America, it is extremely important to wash clothes with good detergent and dry them completely, without leaving moisture, to ensure disinfection. This is the simplest and safest method of cleaning.
What to avoid when using a handkerchief
Many people fold a used handkerchief and put it back in their pocket if it is still damp, which should not be done. Similarly, frequently wiping the face or hands with a handkerchief used to clean the nose is not a good habit. If you have a cold, you need to change the handkerchief often and wash your hands thoroughly after using it.
