This may sound weird but i use what seems to be called a "metal pry spudger" on the googles. Basically a metal spudger/prying tool. It has one rounded end I use as the handle, and a squared off end. I actually happened to get 2 free with a digitizer one time and i've used it hundreds of times since. I use the flat end to just scrape off all the adhesive just like kerri's method, works great, no mess or risk of liquid touching other components and can't cut yourself on them. The moment I see them show up in the store here I'm gonna stock up a couple more. It seems they work for approximately 200 uses for probably what they weren't even designed for XD.
