A multi-material composite, the materials being positioned at raised regions (120/220/320/420) and recessed regions (130/230/330/430) on the working surface (110/210/310,315/410), provides a cleaning device (100/200/300/400) with both scouring and wiping on a single surface. By recessing certain material (s) from the working surface, the user can control, with pressure, the extent to which the recessed region makes contact with a surface to be cleaned (170/270). The composite may have at least a first substrate (140/240/340/440) that is a compressible material, and a second substrate (150/250/350/450) that is a compressible material. |
