Improvements in the manufacture of cleaning provisions by rubbing, characterized by the fact of carrying out the association, by joining, of a continuous layer of spongy material of a certain thickness and a certain degree of softness, with another layer of analogous material, although of greater relative stiffness, so that the solidation between both layers is carried out in order to obtain a single body, which is subject to transversal subdivisions of which portions are suitable for use.
