Abstract
A cleaning utensil includes an elongated handle having proximal and distal ends and a substantially spherical sponge having a cavity for fixedly receiving and retaining the distal portion of the elongated handle. The sponge is formed from material having a first predetermined softness and at least one abrasive scouring element is fixedly attached to a portion of the surface of the spherical sponge. The at least one abrasive scouring element is formed from material having a second predetermined softness where the second predetermined softness is greater in abrasiveness than the first predetermined softness to facilitate cleaning of lightly and heavily soiled areas, respectively.
