It really depends on the surface of the dry erase board. Some interactive boards have a melamine surface while others have a porcelain steel surface. I would check to see if it is a porcelain steel dry erase surface, which would easily allow the markers to wipe off. The brand of markers is important, we have found that BIC dry erase markers work best. As long as the surface is not very porous, the marker will not absorb into the surface causing the ghosting effect. There are interactive whiteboards that do act as dry erase boards as well as projection screens. Hope this info helps!
