Flexible plastic putty knives from Home Depot work wonders and if you get it hot enough but not so hot that it stretches and breaks... preferably with a heat gun then you can peel it of using the putty knife without leaving any residue behind. A good hair dryer will work if you don't have a heat gun.

If you see that it is leaving residue behind then it is not hot enough... heat it some more and try again. Pinstripe removal is a quick painless thing so long as you don't have to rub out a bunch of adhesive residue.:thumbup:
