How to remove dried... something? On the backseat of my car there is what appears to be...

On the backseat of my car there is what appears to be a dried, dripped blob of milkshake. What it if truth be told is I don't know; I'm guessing milkshake because of a couple of kids I had back in attendance a long while ago and like I said, that's what it looks like. I didn't observe it for a long time (I don't look back at that spot very often) and very soon after having been within the sun, it's dried onto the upholstery. I could just try picking it off but I'm afraid of tear the fabric. Any suggestions?
Answers:    Lay a water soaked towel on it and that will loosen it up.
If you want to verbs it as well as get it up,
I would dissolve 1/2 cup oxiclean crystals surrounded by a few cups of warm to hot water afterwards soak the towel in that and place it on the mess. let set for a while and when you move up the towel the stain, odor and mess will be gone.
I'd scrape off what you can next to something dull, like a spoon. Then, it is a matter of going at it near Woolite upholstery cleaner. No doubt it will take 3 or more applications, but it should work, and there will be no violate. are you sure it's milkshake it can be a .
