Use extreme goo gone made by gunk. I use that on detailing jobs all the time. I've used it on interiors and everything, spray a tiny spot first to make sure it doesnt discolor anything platis, and if its good spray the whole thing, peel the sticker off spray the glue and wipe it off with a paper towl or a rag. This stuff, is cheap and works great, i get mine at walmart and it doesnt take much to get that junk off
