Microfiber attracts and holds dust & dirt without use of chemicals — use dry or mist with water for even more efficient dusting. The unique shape allows cleaning in corners and narrow spaces. The cover is easy to remove from the sponge base (made from post-industrial waste) that provides a soft cushion for all-around dusting. The sponge is made of re-bond, which is comprised of pieces of post-industrial sponge waste (the same material that is used as carpet padding). The head can be used with or without the eclipse™ aluminum pole. Machine washable cover, air dry, no fabric softener.
