What can I use to remove the stubborn gummed labels from some diskettes?

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.

Soapy Water: Warm Soapy Water: Soak the diskette in warm soapy water or you can use kitchen degreaser or multi surface cleaner for a few minutes to soften the label. Gently peel off the label and scrub off any residue with a soft brush or cloth.
