Sulfur soap can be used to wash underwear, especially for patients with mycosis fungoides, using sulfur soap to wash underwear has a certain antiseptic and anti-itch effect, but because sulfur soap is more irritating, it is generally recommended to use ordinary soap to wash underwear, preferably by hand, separate from socks and other clothing, use a special washing basin for underwear, after washing in the sun. If you have recent mycotic vaginitis, boil your underwear in water for half an hour to kill the mold. Try to reduce the number of times you go to public baths, pools and spas, and do not have intercourse during treatment to prevent cross-infection.
