This shows plantar warts being treated with a salicylic acid preparation (Occlusal). The acid is a very weak acid, and is generally applied on a daily basis. Before application, the wart
should be trimmed with a #15 or #10 scalpel blade to enhance the penetration of the salicylic acid. Occlusion with tape enhances the penetration of the preparation, but it is not necessary to use and is generally an extra thing to do that reduces patient compliance.
