As part of my business, I'm a sign maker. Goo Gone will definitely get the decal off. Downy fabric softener mixed with some water will also get it off. Just slather it on and let it set for a bit. You might also heat it up SOME with a hair dryer as you pull it off. It will help loosen the glue. If you need some more numbers, PM me and give me the size and I'll be glad to send you some at no cost to you. Anything for a fellow Tide fan.
