According to Mayo Clinic, over-the-counter solutions or patches containing salicylic acid can be used to treat common warts at home over a period of a few weeks. Some studies have also named duct tape as a treatment for warts, although the results of this treatment's effectiveness are mixed.
Mayo Clinic suggests using wart solutions or patches that contain 17 percent salicylic acid. The wart should first be soaked in warm water for 10 to 20 minutes before the treatment is applied, and between treatments, the wart should be filed down with a pumice stone or nail file. The duct tape remedy involves covering the wart with duct tape for six days, soaking the wart in warm water and then filing the dead skin away.
