Abstract
This invention is a foldable material having a surface appropriate for manual, contact maintenance, such as a cloth, of such size as to enable the folding of the cloth into parallel panels, each of which is approximately hand-sized. Each of the panels can be visually discriminated from the others by a line imprinted on the panel surface, and each of the panels is sequentially numbered. The foldable material is folded in half and sewn along the long end forming a sleeve. The invention also includes the method of using the foldable material by following a series of directions as to how to fold the material and then using each of the panels in a preferred order of use, thus maximizing the use of the surface area of the material and eliminating waste or contamination.
