IIRC the recommended approach now is to freeze them off with those wart removers you can find at drug stores. Even the special tweezers were hard enough to use properly that it's no longer the recommended approach.
So I guess the recommendation remains: remove with tweezers carefully, targeting the head so as to avoid sqeezing the body and flushing toxins back into your body. Which is easier than heading to a drugstore for freezing wart removers anyway.
