Abstract

A board wiper, especially for cleaning school blackboards, comprises a holder 1 with handle and a replaceable wiper part 5, preferably composed of a foam material, in which the holder is provided on the underside with a Velcro material 3, and the wiper on the upper side is covered with a Velcro material 4, which is designed to engage with the holder's Velcro material. The holder may be provided with a hook 7 for hanging the blackboard wiper up. If a polyether foam material is used, the wiper may be used dry and hold the chalk dust so that it is not dispersed, and the wiper can be easily replaced without the collected chalk dust being released and dirtying the fingers, for example. <IMAGE>
