Abstract

The present invention teaches multilayer cleaning articles that include a substantially dry surface contact layer and a gripping layer. The contact layer may represent one exposed major face of the cleaning article (e.g., a cleaning pad), while the gripping layer may represent the opposite exposed major face of the cleaning article. The contact layer may include abrasive synthetic fibers, so as to be effective in scrubbing soils and spills from a surface. The contact layer includes a cleaning composition pre-loaded therein. The cleaning composition is such that the contact layer feels dry to the touch prior to use, before wetting with water. The cleaning composition may include about 1% to about 40% by weight water. The gripping layer includes at least 40% by weight of pulp fibers (e.g., natural cellulose pulp fiber), and exhibits a mean hand grip value that is at least 0.015 1/in2 (reciprocal inches squared).
