Yooz dry erase marker to remove old dry erase marker marks on a white board

When a dry erase marker mark on a dry erase board sits too long it can be difficult to get off. To remove, simply take a dry erase marker and scribble several times on the stuck-on mark. After doing this, the old and new marks can be erased or wiped away. The new mark moistens and loosens the old mark from the board.
