Look up wikipedia. Quickly conclude that salicylic acid treatment is the most effective of the non-invasive treatments. If that doesn’t work (unlikely) then start to consider the interesting options like lasers and immunotherapy. (The immunotherapy option looks kind of fun. You can treat one wart topically and it makes warts elsewhere on your body go away too!)
