Stickey Games

[Stonecutter]

For the first time this generation, I've picked up a used game. It works fine, so all is good, but the game had some stickers put directly on the case, and as you might imagine, trying to remove them wasn't very successful.

My question is: does anyone know any tricks to try and get that sticker goop up off the dvd cases? There's got to be something. I know peanut butter works well, but I don't want my cases smelling like peanut butter.
