Public washing machines are definitely not that clean. Some people will wear it to wash their shoes, and there is no guarantee of hygiene. If you really want to clean your clothes, the best way is to wash them by hand.

First, disinfection is not very thorough.

Most schools provide students with a washing machine on each floor, and students on this floor will come to this washing machine to wash clothes. The school will ask these aunts to disinfect all washing machines in two or three days. Washing clothes in the newly disinfected washing machine is very clean, but the washing time is too late to ensure that the washing machine is still clean.

Second, each student loves cleanliness to a different degree.

Both boys' dormitory and girls' dormitory have serious cleanliness addiction, and there are also very untidy students. Some students will also ensure the cleanliness of the washing machine when using it. They only wash their ordinary clothes, and the more private clothes will be washed by hand. But for those sloppy students, they may be too lazy to wash socks at ordinary times.

Many people will use the washing machine to wash socks or close-fitting clothes, which will cause the clothes of students who use the washing machine to be not very clean and have some peculiar smell.
