How to get rid of warts

My grandmother  from Kentucky told everyone she met this. She believed that if you had warts, if you peed on a dishrag and buried out in the street, soon the warts would disappear. She made everyone in the family do it whenever they found a wart and swore by it working.

This being my great great grandmother, passed this superstition belief down for many years so maybe there was some truth to it when she did it. It was probably coincidence that she somehow thought to pee on a dishrag and bury it in the street when her warts went away.
