Wash with water saturated with common washing-soda, and let it dry
without wiping; repeat frequently until they disappear. Or pass a pin
through the wart and hold one end of it over the flame of a candle or
lamp until the wart fires by the heat, and it will disappear.
Another treatment of warts is to pare the hard and dry skin from their
tops, and then touch them with the smallest drop of strong acetic
acid, taking care that the acid does not run off the wart upon the
neighboring skin; for if it does it will occasion inflammation and
much pain. If this is continued once or twice daily, with regularity,
paring the surface of the wart occasionally when it gets hard and dry,
the wart will soon be effectually cured.
