Using bleach (chlorine bleach) to treat athlete's foot (tinea pedis) is not recommended. Bleach has strong chemical properties and may cause skin irritation, burning or allergic reactions, especially when used on sensitive foot skin. **Recommended treatments include:** 1. **Antifungal medications:** There are many over-the-counter antifungal creams, sprays or powders on the market, such as Clotrimazole, Terbinafine, etc. These products are specifically designed to treat athlete's foot and are effective and relatively safe. 2. **Keep your feet dry and clean:** Fungus thrives in moist environments. Make sure to wash your feet every day, especially after activities, and dry them thoroughly, especially between the toes. 3. **Wear breathable shoes and socks:** Choose socks made of cotton or other moisture-wicking materials and avoid wearing shoes that are not breathable to help keep your feet dry. 4. **Change shoes and socks regularly:** Change to clean and dry socks every day and avoid wearing wet socks or damp shoes. 5. **Avoid sharing personal items:** such as towels, shoes, etc. to reduce the risk of cross infection. **Please note:** If your athlete's foot symptoms are severe, lasting for a long time, or accompanied by other symptoms (such as severe pain, ulcers, redness and swelling, etc.), it is recommended to consult a doctor or dermatologist as soon as possible for professional diagnosis and treatment advice. Athlete's foot can usually be effectively treated using the right methods and products, and avoid using strong chemicals such as bleach to prevent unnecessary skin damage.
