I remove moles all the time with iodine. The few that have been resistant, I've finished off with Hydrogen peroxide a couple times a day. Note...one on my back got huge (sticking out ) after I started using iodine. I think the iodine caused mole to start ejecting from body from the base. It took awhile but finally totally went away also.
Hydrogen Peroxide and Iodine
I've tried iodine and/or hydrogen peroxide 3% and they too would often get bigger and turn black but with enough time, it always worked. I liked to visualize they got bigger as the inside mole was working its way outside :)
