Well everyone I have recently discovered the all time best adhesive removes EVER. Believe it or not WD40...YES that'z right WD40. I have 4 pair of scissors with seriously bad adhesive all over them to the point they would not open. I know...I know I need scissor help BUT....I sprayed WD40 on them and waited about 2 minutes and it wiped off clean. My really bad ones I had to repeat the process twice but it worked like a champ. After...I rinsed them with water and let dry and they look brand new. Can you beleive that. Super cool!
