"Tornado"
You can probably get tornado at any car auto parts store but it will not usually be in with the regular car wash. Sometimes its with some other cleaners and solvents. I had heard about the stuff from a bunch of older guys I was talking to at a car show. They know what they are talking about and even use it on their classic cars.
Its actually not a bad idea to wash your car with the stuff every once in a while, it will take off the deep down dirt that regular car-wash cannot take off. It is a very strong cleaner so it needs to be diluted.
As far as goo-gone, I'm not totally sure if that would work. I never used it before on a car so I dont want to tell you anything that I dont know about.
