Oops! Erase Sharpie Marks on a White Board

Erase Sharpie Marks on a White Board.

Oops! You just used a Sharpie on your White board instead of a Dry Erase Marker.

Scribble over the Sharpie Writing with a Dry Erase Marker.

Wipe off with a eraser or a paper towel. And poof! The Sharpie writing is gone!

If there is still faint writing just scribble over it in dry erase marker again. Now it should be gone.
