Removing years old Rolex caseback sticker?

[dinosaysrawr]

So I just received my 1996 T-serial Explorer ii, and on the caseback is what seems to be a Rolex sticker that protects the caseback from getting scratched. Not sure if it's original, but it certainly is years old as it seems to have some sort of stain underneath that seems super old (it might be discoloration of the old adhesive). I want to take it off and get it cleaned, does anyone know what this sticker is and how I can remove/clean it without damaging the caseback?

The sticker has the Rolex logo and model number "16570" embossed(?) on it, which is why I'm assuming it might be the original sticker.
