Abstract: The curved cleaning element is made by providing a cleaning material with a back surface and a working surface that together define a volume and thickness. A portion of the cleaning material is removed at a pivot zone. The pivot zone separates the cleaning material into a first portion and second portion. At the pivot zone, the cleaning material has less thickness and/or less volume as compared to either the first or second portions. In one embodiment, the back surface of the first portion of the cleaning material is attached to a support and the second portion of the cleaning material is pivoted at the pivot zone. The second portion of the cleaning material is secured to either the support or the first portion of the cleaning material to form a continuously curving working surface of the cleaning material.
