If you write on a dry erase board and leave your message up for long periods of time, you might find that the marks don't erase easily or that they leave deep stains in your board. This can also occur with prolonged regular use. Dry erase boards also get old and the marks don't come off as easily. Deep stains on dry erase boards are moderately easy to remove, and the board's surface can be reconditioned to avoid future staining.

Make a simple solution of one part vinegar to four parts water. The acid in the vinegar is effective at removing dry erase board stains. Apply to the solution to stains and then wipe the board clean, using a damp rag.
Use hairspray. Hairspray has a high alcohol content, but isn't as strong as pure alcohol. Spritz the stains with hairspray, let soak for a few seconds, then rub with a paper towel. Wipe the area down with a wet rag afterward to remove the sticky, tacky feeling. If this isn't completely effective, try the same method with hand sanitizer. Hand sanitizer has a higher alcohol content and often gets most stains out of dry erase boards. It can also be harsh on your board's surface, so use it only if the first two methods fail.
Try toothpaste. For especially stubborn stains on your dry erase board, dab some toothpaste onto a clean rag and rub the stains out by using small circles. Toothpaste has a small amount of grit and will scrub the board without scratching the surface. Scratching the surface of your dry erase board will ruin it and make future marks difficult to remove.
Use coffee if you have accidentally written on your dry erase board with permanent marker. The acid in coffee breaks down the permanent marker ink, making it easy to remove.
Restore the surface of your board by buffing it with a small amount of mineral oil. This will fill in minute cracks and restore the board's finish. A restored finish resists stains and releases marks more easily.
