When do I know the wart is gone? I have used Compound W bandages a few different times, and just?

Warts are caused by a virus and sometimes you could everything but it wont go away. Like all viruses they may one day wear out it's life ... but unfortunately we can't put a time on the virus that causes warts. So for some people it may go away in a few months, for some in a year or so.

It's really hard to tell. All the best.
