Disinfecting feet after a pedicure is crucial to prevent bacterial and fungal infections. Various methods can be used, such as white vinegar soaks, hydrogen peroxide sprays, or epsom salt bath soaks for 10-15 minutes each. Best hygiene practices include washing hands before touching own feet, avoiding shared instruments, and keeping nails short. Specific areas like toenail beds and cuticles require targeted disinfection methods to prevent infections.
