Cannot Remove Sticker Goo on Door of New Sharp...

Question

Just purchased new and when I removed the large oval sticker on the door the sticker left goo on what appears to be a thin plastic sheet. Cannot figure out if the thin, flimsy plastic is removable or part of the door? There doesn't seem to be a way to remove it and I don't know how to remove the goo without damaging the thin plastic (kind of like a clear drum).
