There is a product that is sold by Home Depot. It is in the air refresher department. It is an orange fragrance and works great. They use that to get glue off shelf stickers at Home Depot. I think the citrus is what makes it work. Much cheaper than Goo Gone and much less work. Spray the sticker, let it soak in a couple of minutes and then use a plastic putty knife to remove the sticker. Spray as you remove as well. Then wash and polish the area. Dont let it run as it will remove the wax.
