A.D.
Well, I have no personal experience. But, I read an article from either Parents or Parenting mag. that said to get duct-tape. Cut out a circle a little bigger than the wart - gently but firmly place on top of wart. Leave and/or refresh tape if it gets yucky until wart has disappeared. Don't know if it works or not, but I assume it'd be safe since it appeared in the mag. Might give it a whirl! :)
