A clogging phenomenon in the surface layer of the contact face of a soft plastic-and-abrasive composite for polishing painted surfaces, which reduces the efficiency of the polishing work, is alleviated by mixing into the soft plastic backing material of the composite containing abrasive fine particles, non-abrasive globular particles preferably formed out of bubble material. The globular particles are rotatable in the surface layer of the contact face of the soft backing when the composite is in rubbing contact with the surface to be polished. Water or a surfactant may be interposed between the surface to be polished and the composite. The surface to be polished is rubbed with the composite to remove contaminating substances adhering to the surface to be polished.
