0 1 Separate cleaning
Don't soak underwear with other clothes, especially socks. Everyone should wash their underwear separately, children's, men's and women's.
Thoroughly clean
When washing underwear, don't think that changing underwear every day is not dirty at all, just wash it with water. Be sure to use mild emulsion products, such as mild soap powder, and be sure to rub the crotch of underwear hard and wash it clean.
Use hot water
After washing underwear, put it into a basin, soak it in boiling water for ten minutes, then take it out, wash it again with clear water and soak it.
04 sunlight exposure
Underwear should not be dried in the shade, but must be exposed to the sun, so that it can be thoroughly disinfected and sterilized, and it will not be infected by bacteria when drying.
