After having stubborn verrucas for 20yrs+...and having treatment at a podiatrist for the last 12months,id like to share something that was recommended as a last resort by my podiatrist, as nothing seemed to work. A schol hard skin remover to grind the verruca down, then apply surgical spirit with a cotton wool ball. 2months and they are gone😁... Give it a try, but stick to it every day. X
