How about washing underwear and socks with a washing machine in college?
It is best not to wash socks and underwear together, because there will be a lot of bacteria and fungi in socks. Be careful that my little brother gets sick in underwear. My suggestion is that socks and underwear should not be washed together or in the washing machine. It is best to wash it by hand. A small matter is solved three times, five times and two times, which is healthy and hygienic. May you be healthy!
