there is a company out of Merlin OR. that sells a product called Rapid Remover. it works much better than Goo Gone. jut head to the kitchen sink with a squeegee and hose it down with the Rapid Remover. Then squeegee off the glue. if the color starts to bleed just rinse it off and reapply the Rapid Remover. then repeat until glue is completely gone. usually it works on the first try. the glue will come up best if ya peel the vinyl at slightly warmer than room temp. then if there is any left use the Rapid. you can also buy Rapid Remover from a company in Eugene OR. called Multi Craft Plastics.
Hope this helps
