Abstract
Abstract Integrally molded impaling spikes are positioned in aligned longitudinally and transversely extending rows throughout substantially one side of an applicator head. A cleaning component is provided with a layer of fibers to be penetrated and engaged by the impaling spikes when the cleaning component is pressed against the applicator head so that lateral movement of the cleaning component is prevented during use of the cleaning device. The cleaning component may be easily stripped from the applicator head for replacement by another cleaning component.
