Abstract: A cleaning apparatus (10) for removing a substance from fabric. The cleaning apparatus comprises a foam substrate having a thickness (TH) between a top surface (11) and a bottom surface, wherein an outer edge (13) is defined along an exterior perimeter of the thickness. The cleaning apparatus also comprises a central portion (ID) having a continuous shape interrupted by a plurality of discontinuities (141 through 144) extending from the top surface to the bottom surface along the outer edge. Still further, the cleaning apparatus comprises a plurality of protrusions extending outward from the central portion, wherein each protrusion is located between two discontinuities in the plurality of discontinuities.
