wrote with permanent marker on electronic white board, now cant get it off.
any tips please.
i have tried going back over it with a dry marker and rubbing off-doesnt work.
tried a little bit of alcohol- didnt work.
tried a standard pencil eraser-worked a little bit but cant get it all off.
any tips would be great as this item cost the school a lot of money and i would like to get it cleaned asap.
many thanks for all your help.
