Nasty, although all I do is to produce a small blister under the
wart, which
lifts it off without any permanent scar.

The thing is there are different kinds of warts:

The raised molehill kind ok for the soldering iron or freezer.
Those that grow thin and long and are suitable for tying off.
The flat red area kind that are really a lot of tiny dots that slowly
spread out and are only suitable for proper surgical removal.

Any more?
