Soapy water
To prevent this infection from spreading or infecting other areas of the body, keep the skin neat and clean. If you have mistakenly touched any surface contaminated with the infection, then rinse the area with soap and warm water one time or two times and clean the infected area with soap.
Before you apply anything in the affected area, it is safe to first try it on the healthy area of skin to ensure they don’t have a sensitivity or allergy to the treatment.
