Product Description Kores Whiteboard Cleaner is a solvent-based non-flammable, transparent liquid cleaner. It is used to eliminate marker ink residue, grease and dust from the whiteboard surface, giving back its original characteristics. Thus, not only will it help to keep your whiteboard looking clean at all times, but it can also help to extend the life of your whiteboard. Kores whiteboard liquid cleaner must be applied after dry cleaning (for example, after wiping the board with Kores Whiteboard Eraser). Whiteboard cleaner is supplied in a 250ml spray bottle.
