Thank you! To remove stubborn gummed labels from diskettes, you can use rubbing alcohol or nail polish remover. Simply apply a few drops of the solution onto the label, let it sit for a few minutes, and then gently rub the label with a soft cloth or cotton swab until it comes off. Be sure to wipe away any excess solution with a clean cloth. However, be cautioned not to apply too much pressure or any sharp object as this can cause damage to the diskette.
