Abstract: In an article suitable for wiping surfaces which comprises an elongate web substrate impregnated with a liquid composition, migration of the liquid along the length of the substrate is substantially prevented by dividing the substrate into a plurality of individual areas by means of a repeating pattern of liquid-repellent barrier material, for example, wax or certain resins, extending across the whole width of the substrate.
