The time that foot fungus survives on clothing is related to the environment in which the clothing is located. If the environment is humid, it can survive for a long time, but if it is in a dry and ventilated environment, or in a sunny environment, it will survive for a shorter time. Foot odor is caused by fungus, which is generally heat-insensitive and sensitive to chemical disinfectants. Therefore, if the foot odor stays on the clothing, the clothing can be placed in the sun for rapid sterilization. You can also spray formaldehyde, phenol, tincture of iodine, peracetic acid and other chemical disinfectants to quickly kill the fungus. Foot fungus is contagious, foot fungus patients need to configure a separate foot wash basin and foot towel to avoid infecting others. In addition, patients with foot fungus need to pay attention to keep the skin of the feet clean and dry, wash feet regularly, change socks regularly, and choose comfortable, breathable shoes and socks to reduce the breeding of foot fungus.
