Duct tape. Instructions: https://www.wwl.nhs.uk/media/.leaflets/5fdb388f0f5623.15599860.pdf
I've heard this is effective, will give it a whirl!I used a little piece of duct tape on a wart and not only did it cure that wart, a couple of other ones I didn't know that were warts, also got cured. I held the duct tape in place with a plaster, and changed both often, and kept the treatment going for a few weeks.
