PURPOSE:To provide the cleaning goods which is convenient to store and carry and can remove the stains securely sticking to a solid surface simply by rubbing while impregnating water by incorporating a polishing material and surfactant into low-density cellulose sponge and compressing the sponge to a compact shape. CONSTITUTION:A liquid detergent compsn. contg. the polishing material and the surfactant is sprayed on the surface of the low-density sponge of cellulose and cellulose deriv., etc., or the sponge is subjected to immersion in this compsn., etc., and is dried; thereafter, the sponge is compressed by a press roller, etc. The polishing material is formed by using a material which forms a solid surface to avert flawing. Calcium carbonate, etc., are used for this material and the Mohs' hardness is adjusted to 2 to 4. Or the Mohs' hardness is adjusted to 1 to 2.5 by using hydrous magnesium silicate, etc. Various kinds of anionic, cationic, nonionic and amphoteric surfactants which are generally used are used for the surfactant. The sponge is thereby made into the extremely compact shape. Cleaning of the solid surface is executed merely by impregnating water in the sponge as the sponge previously contains internally the polishing material and the surfactant. The cleaning is thus extremely simple. |
