Milk spots just pick out with a sterilised needle, will come out like a hard white lump of fat,might get a bit of blood but dont worry.
Warts on scrotum or anus tie off very tighly with cotton to stop blood flow to them, within 10 days will turn black, hard and fall off, and they wont come back, minimal if any scarring, they are basically just sags.
Easy as pie!
