cleaning flexwatt

I used some foil tape that my roommate had to attach my flexwatt to my shelves. The problem is it is not sticking and when I take it off the entire flexwatt is covered in gunk. How can I get the gunkly gummy junk off my flexwatt without runining it? Thanks

Goo Gone would probably take that right off there. You can find it at lowes, home depot, etc.
