goof off works better than goo gone, i tried some goo gone on some industrial strength velcro that i had on y car windows and it did nothing, so then i tried some hairspray and it did nothing.... so then i used professional strength goof off and it took the goo off of the window almost instantly i had to apply it a few times to get all of the residue off but in the end it cleaned everything up ( an this was on my tinted windows on the inside where the tint is) didn't do any damage to the tint so yeah im happy with those results...
