Quartet Magnetic Microfiber Whiteboard Cleaning Cloths - Magnetic, Washable, Reusable - Black - MicroFiber

These cloths are particularly well suited for cleaning whiteboards because of their "magnetic" attraction to dirt and dust, while they are extremely soft so they won't scratch sensitive surfaces. Cloths remove all dry erase ink along with any other substances. And unlike felt erasers, they can clean large areas, then be washed, dried and reused again and again.
