How do you make dried expo markers work again?

To revive dried expo markers, start by dipping the tip of the marker in a small amount of rubbing alcohol or water for a few seconds. Cap the marker and let it sit upright for a few minutes to allow the ink to flow back to the tip. If the marker still doesn’t work, try shaking it gently or repeating the process a couple of times. If these methods fail, the marker may be too dry to restore.
