am not a doctor, but I must emphasize that there may be serious risks in using bleach (even diluted) to treat athlete's foot. Bleach is a strong chemical, and even if it is used in the "ratio" shown in some online posts, its irritating and corrosive effects may cause harm to the skin, such as burns, allergic reactions, or other skin problems. In addition, there is currently no reliable medical evidence that diluted bleach is a safe or effective treatment for athlete's foot (fungal infection). Athlete's foot is usually treated with clinically proven antifungal medications, such as topical antifungal creams or sprays. The correct treatment method and ratio should be based on the advice of a medical professional. For any skin infection, safe and effective treatment options should be based on scientific guidance and the advice of a doctor. If you are considering using other methods (including diluted bleach) to treat skin problems, always consult a professional medical staff first to ensure that there will be no irreversible damage to your health. Please follow safe and professional medical advice and do not try risky methods on your own.
