What is whiteboard ghosting and how do I prevent it?

Ghosting is the faint shadow or stain left on a whiteboard surface after erasing, visible when the board is viewed at an angle or in certain lighting. It is caused by marker ink penetrating a porous or degraded writing surface. Melamine boards ghost quickly; porcelain and glass boards resist ghosting for years when properly maintained. Prevention: always use quality dry-erase markers rated for the board type, clean with a dry eraser after each use, and perform a deep clean with isopropyl alcohol weekly.
