How do you get perminate maarker off of piano keys?

To remove permanent marker from piano keys, you can use a cotton swab or soft cloth dampened with isopropyl alcohol or rubbing alcohol. Gently rub the stained area, being careful not to damage the key's surface. For stubborn marks, you can try using a magic eraser, but test it on a small, inconspicuous area first. Always clean the keys afterward with a dry cloth to remove any residue.
