On the winshield of my car right at the top on the driver's side there is a warning sticker. It is the focal point of my stare when I do not have the visor down. The sticker is right in my eye line and bothers me quite a bit. I tried ripping it off, but it left a a large area of sticky stuff. So I put the sticker back over it. Is there anything that I can do to get it off?? Is there a product that I should try? Any suggestions are appreciated. Thanks in advance.
