In days gone by before vinyl came out we used to use oven cleaner to remove signwriting, with differing results.
Not that I ever did it, or needed to as I never did any traditional aspects of sign making or writing but I remember a few from this site many years ago swore by this. a few Americans too.
My only worry about these types of products, is some have a fine scouring ingredient that may dull the sheen from the vinyl.
