I've gotten rid of warts on my skin before using Apple Cider Vinegar.
Soak a cotton ball in straight Apple Cider Vinegar and then Apply The Cotton Ball to the wart and tape it onto the wart and leave the Apple Cider Vinegar soaked cotton ball on the wart overnight or all day.
The Apple Cider Vinegar is antibacterial and will kill off the virus causing the wart and the acid contained in Apple Cider Vinegar will eat away at the wart.
I had to Apply The Cotton Ball and Apple Cider Vinegar 2 nights in a row but after the second night the wart went away.
