Re: Taking off stickers
Local sign shop or artist supply store should have a plastic "blade" like tool called a burnishing tool. You use it to burnish decals on, but you can also use it to get the edges of a decal off the surface. Once you get that edge up, you can apply a little heat, pull straight back (almost fold the decal over on itself) and go slow. When it tears, grab that blade and get another edge going. Rinse and repeat until the decal is off.
Unless the decal is REALLY brittle that should be the easiest way to get it off without damaging anything.
