The center area of each is compressed between a securing member and fastener head. The fastener has a stem which is inserted through the locating apertures and held by the securing member. The cleaning elements tangle and engage with each other because of the compression and because edges of each of the cleaning elements is formed of protruding ends of yarns of the net material which engage within interstices of neighboring ones of the cleaning elements. The protruding ends at the free ends of the cleaning elements as well as both sides of the cleaning elements constitute abrasive surfaces which clean external surfaces of particulate matter when moved back and forth against the external surfaces.
