When it comes to removing the old tape adhesive residue the best product in the U.S. is Lift Off #2. It works well, does not leave a residue, and will not harm any surface. http://www.liftoffinc.com/

Goof Off http://www.goofoffstainremover.com/ may work but must be used in a well ventilated area and in fine print says not to use on some plastics.

Goo Gone leaves an oily residue that is almost as bad to get rid of as the tape residue.

Krud Cutter Adhesive Remover is not as good as Lift Off #2. http://www.krudkutter.com/index.php?...d=15&Itemid=71
