Is there a way to restore the finish of a dry erase board? - lo board

I work for my brother and I kissed her dry erase his great painting! I tried to write a book to do for your children. While I was looking at the computer, was looking for a pencil w / o, and began to write an address on the blackboard. And here I make a mistake and it will not be deleted. Someone put a damn permanent markers on the shelf! So I panicked and a platform of green bushes and wash my face wet! I do not think even the shiny surface! Is there a way to restore them? My feeling is there, but would not hurt to ask. Please help me, I feel bad because I know this is a requirement of his face. Thank you!
