I have used the following method successfully to get rid off a stubborn and fast spreading mosaic wart along with multiple warts that started popping on the foot and a plantar wart on a hand. First use compound W freeze off advanced to freeze the wart (this was a start but did not alone get rid off the wart) Next start the following routine 1) wipe the area with a strong hospital strength alcohol wipe (or use strong nail polish remover) 2) apply dr scholls salicylic drops 3) after the drops dry and form a crust, apply a coat of clear enamel nail polish (this is far more targeted and effective than duct tape which slips and falls off) 4) after the enamel dries wipe the surrounding area with alcohol wipe Repeated this process twice a day for two weeks. All the warts became dead and fell off . Other tips) put on a fresh pair of cotton socks every time after treating the areas on foot 2) threw away all socks after every treatment. 3) after warts were gone got new shoes and threw old ones away. 4) continued alcohol wiping the area for two more weeks after all warts died 5) very careful about using public swim places going forward
