I used Bic Dry Erase markers on the board. I attempted to erase it with a dry erase eraser but it just smeared it. Then I Expo Dry Erase spray, since the Activ Board manual shows that spray is allowed in one of the pictures. Most of it came off with a lot of rubbing with a clean cloth and the spray, but there is still one spot that has left a discolored streak. This board has only been in use for three days. How can I get rid of the streak? Now I don’t dare use dry erase markers on it even though ActivBoard claims they are safe. Please help. Thank you.
