the graphtec we have always seperates from the adhesive, so here is what I have to do. It's a little painful but works well to clean off all the glue. I use one of those l'il chizzler tools and slowly work it along the glue. I also will rub my thumb along the glue as it seems to be the best way to get it off. It sort of rolls the glue up bit by bit Thats where the pain comes in, take your time as you will slowly wear out the skin on your thumb lol. Ouch!!!
