Killing my warts off

Today I decided to remove my wart, I had this thing on top of my nose with a mole in it. So, i read some articles about warts removal, they said it is better to consult the demartologist or a surgeon. But, some websites teaches on self removal of this annoying warts. I have found three solutions, first is the duct tape theraphy which you will put a duct tape over and over til the warts fell off, second is the cider vinegar which i think is the best and the one i uses, and the third is the banana peel, they said banana is rich in potassium so, with the banana peel put on top of the wart will remove it completely after some days.
