WD-40 can be a lifesaver for teachers who accidentally use permanent markers on whiteboard. When sprayed onto the affected area, WD-40's lubricating properties help to dissolve the ink. This allows them to wipe away the permanent marker easily with a cloth, restoring the whiteboard to its clean, usable state. WD-40 breaks down the ink, making it easy to remove without damaging the whiteboard surface, ensuring the lesson can continue smoothly without distraction.
