In one sentence, describe what the following article is about:

Choose a medicine for wart removal that contains salicylic acid. Salicylic acid in high concentrations will cause the wart to die. You can find salicylic acid wart removal medications in the foot care section of a drug or grocery store. Apply the medication directly to the wart before you cover it with duct tape. Try to avoid getting the medication on the skin around it. The medicine will cause the skin to die and turn white.  Make sure to follow the manufacturer’s instructions for how to use the medicine. This is optional, but it might help to make the duct tape therapy go faster. Using duct tape alone to get rid of the wart may take up to 8 weeks.
Apply wart removal medication if you want to speed up the process.
