I can confirm the vinegar method. I just used generic vinegar.
My warts were on my thumb.
1st, I cut away the thick skin layer of the wart to expose the living part, it bleeds a bit.
Then cut digit off cheapo latex glove, put 4-5 drops of vinegar in, then put latex digit on my thumb. Kept it on for as much time as I could over about 3 days, refilling the digit with fresh vinegar about twice a day.
Warts didn't come back. great because I'd had them for years, and tried and failed a few times before to get rid of them.
