Hey everybody!

So, the rather short story is that I have a used car. When I bought it there were some stickers on the interior side of the windows, unfortunately they have been there so long that they've cracked/split or something and they are pretty solidly stuck, anyone have a sure and fairly non-toxic solution to removing stickers off glass like that?

I've occassionaly considered trying to soak it in Simple Green or somesuch but I'm not sure how to do that short of paying a sibling to sit in the car and hold a rag on the window.

Any ideas? Experience? Strange dreams you had once about sticker removal?
