What is surgical spirit different then the 80% alcohol bottle you buy at the pharmacy?
Because I tried it and it didn't give that good result.
The main thing is, that I perform the effect on spectators in real time, so I want to remove as much as I can on stage after I finish.
Right now what I do is to use the minimum amount of RC I can, and after rubbing what I can off (and it's not a lot, because if it looked like I'm putting to much work into it, it would look suspicious), I place a medical pad on it, with 2 blood dots on it from the inside. that way I can hope they won't check it until after the show, and by then it's only them wondering why their skin is peeling on their arm
