Abstract
A covering includes an outer material, a plurality of conductive-fibers, and a fastening material. The outer material includes a front surface and a back surface and the conductive-fibers are disposed between the front surface and the back surface. The conductive-fibers are configured to receive a voltage that causes the conductive-fibers to repel and remove dust from the front surface of the outer material. The fastening material is coupled to the back surface of the outer material and facilitates releasably attaching the outer material to an article.
