Patent ID: 8778086

Claim:
A method of cleaning residue from a surface, the method comprising: (A) providing a disposable cellulosic wiper comprising (a) from about 25% or more by weight of pulp-derived papermaking fibers, the pulp-derived papermaking fibers having a characteristic scattering coefficient of less than 50 m 2 /kg, and (b) from about 25% to about 75% by weight of fibrillated regenerated independent cellulosic microfibers, the microfibers (i) being finer than 14 mesh, (ii) having a characteristic Canadian Standard Freeness (CSF) value of less than 175 ml, (iii) having a number average diameter of less than about 2 microns, and (iv) being selected and present in amounts such that the wiper exhibits a scattering coefficient of greater than 50 m 2 /kg; (B) applying the wiper, with a predetermined amount of pressure, to a residue-bearing surface; and (C) wiping the surface with the applied wiper, while applying the predetermined amount of pressure, to remove residue from the surface, such that the surface has less than 1 g/m 2 of residue after being wiped under the predetermined amount of pressure with the applied wiper.
