Abstract: A single sweep eraser system allows cleaning of a whiteboard with a single, simple and rapid motion across the board. The system provides track brackets and glides that support a cleaning bar applying sufficient pressure to a cleaning pad extending the height of the board to provide broad area cleaning without the need for the user to “lean in” hard against the cleaning pad. The tracks conveniently hold the cleaning bar off to one side of the board for ready access.
