I like Goo-Gone. But it's pretty flammable. And since I ran out of it and haven't bothered to buy more, I started using olive oil instead. Back when I was reading up on the many uses of olive oil, I learned that you can use it to clean sticky residue off many surfaces. I've tried it quite a few times and have found that it does quite well. The only draw back is the oily residue you are left with. But to remedy that, I just spritz the area with some 50/50 vinegar water solution (handy cleaning solution) and wipe it off. You can use other cooking oils for this purpose as well.
