A cleaning device 1 and method for making which is constructed from a thermoplastic material 2 to which a plurality of fibers 3 are fused and protrude therefrom, and formed into a curvilinear configuration such as a helix-like, or U-shape-like configuration. The method includes the steps of heating the base 2 until it is softened and bent to a U-shape like configuration and then cooling the base member 2, or helically winding the base 2 onto a rotating mandrel 11; stopping the mandrel 11 and severing an end of the base member 2; and cooling the base member 2 so that it retains its U-shape or helical configuration.
