How Do You Use Dry Ice to Remove Warts?

It is possible to remove warts by using a freezing spray that is similar to dry ice and that is available over the counter; the spray forms a blister around the wart that eventually falls off, according to the American Academy of Dermatology. The AAD warns to not attempt freezing warts off with ice cubes as this will not work.

The AAD also advises that warts can be removed with liquid acid or acid patches. These patches utilize salicylic acid to peel away the skin slowly, which also peels away the wart. These acids are available at most drug stores over the counter.
