Boyd Visuals Natural WhiteBoard Cleaner & Restorer cleans Whiteboards without leaving traces of harsh chemical fumes or residue. Our Whiteboard Cleaner is the natural way to get a thorough streak-free clean. The biodegradable plant and mineral-based ingredients work as well as traditional Whiteboard cleaners to not only remove Whiteboard Markers but permanent pens as well. Directions for use: Step 1. Spray the cleaner onto the whiteboard surface. Step 2. Wipe with a clean paper towel. Alternatively, spray onto a clean cloth and then wipe the board. To help remove permanent pen marks write over the permanent pen with a whiteboard marker then spray and wipe clean with whiteboard cleaner.
