To give you a most simple and money-saving method, the key is to see the effect. The vinegar essence (that is, 30% acetic acid, supermarkets sell) and flour mixed into a paste, a layer of paste before going to bed, a little pain, can be endured, really can not stand to wash off. The next day warts on the black, in order to ensure the effect, you can paste a day, to make sure that the root of the warts are also dead. The black scab is good! (Actually the weak acid corrodes it away, hehehe.) I got rid of 3 on the back of my hands this way, and it cost me no more than 10 bucks! I've recommended it to many people, and it works like a charm! It leaves a light scar that won't be noticeable for a year, but use caution if you're using it on your face! Feel free to reprint this so more and more people can get rid of their warts.
