Do not pumice too hard or too much. The pumice should not hurt, and you should stop once you buff away the dead skin. Stop if you feel any pain, irritation, or discomfort. Do not share a pumice stone with others, as this could lead to infection.
If you use a liquid treatment, you may opt to apply a bandage after you apply the treatment to keep the area covered and the acid contained.
Repeat the soaking and pumicing process every time you change out the duct tape. Continue this process for no more than two months. If the treatment is not working, try another over the counter treatment, or contact your doctor for further care instructions.
If you do come into contact with warts or with surfaces that have been touched by someone with warts, make sure to wash your hands and any other exposed areas carefully with soap and hot water.
