Our whiteboards are made in the USA of sturdy, stain-resistant materials. For daily use, you will normally only need to wipe it clean.
If your student mistakenly uses the wrong type of marker on the whiteboard, try to remove it with a soft, damp cloth. If this does not work, try coloring over the mark with a dry-erase marker and then erasing. If the mark persists, use whiteboard cleaner or non-acetone fingernail polish remover. Never use abrasive cleaners, which will damage the surface of the board.
