During the weekend, i let my sister use my mp3 player, she accidentally dropped nail polish on the screen. I tried to use nail polish remover, all that got left was this smudge dirt on the screen. It has no feeling to it but it looks like there stains on it. I can’t remove it with anything. It looks like glue but smudged on the screen. It came out of no where after i applied nail polish remover. Any answers?
