Cleaning Glue Residue on LCD screen

After removing broken digitizer on iPad 3, I use a little bit of crazy glue on top of a new digitizer with sticky tape to enhance the holding power. It worked out great in terms of holding the digitizer down, but in the process of closing the cover, a bit of crazy glue got on the LCD screen and made a streak mark.

I went to the crazy glue site and only solvent can remove the crazy glue from glass is acetone (nail remover). I was wondering if any one knows if it is safe to use on LCD screen?

Thanks,
