Heat it up with a heat gun or hair blow dryer, then just pick at the edge with your fingernail. Then just get it going and peel it off. Sticky stuff will probably be left behind. Use some Goo Gone to loosen it up. Let it work. Get a rag and wipe off the goo. Don't rub too hard. Keep doing it until all the sticky stuff is gone. Then to get it all shiny, polish the area and wax it.
DON'T use Goof Off. Goof Off and Goo Gone are not the same thing. Goof Off is too strong.
