Abstract
There is provided a wipe for the removal of bacteria from surfaces. The wipe has a positive charge that may be developed through the use of cationic treatments. The wipe may be dipped in an aqueous solution of a non-antimicrobial treatment having a positive charge and the excess solution squeezed out of the wipe. Treatment of the resulting coated wipe with heat at a temperature and for a time sufficient adheres the coating to the wipe. Alternatively, a non-antimicrobial, cationically charged chemical may be imbedded in the web such that it will bloom to the surface when the wipe is exposed to water. The web is desirably a pulp and synthetic fiber fabric made by coforming or hydroengling and may be a laminate including other layers. The treated web removes a substantial amount of the bacteria from a surface yet does not appreciably inhibit the growth of the bacteria. The web does not contain harsh chemicals and so is mild in its effect on the user'"'"'s skin. The removal of the bacteria in contrast to killing the bacteria does not encourage it to develop immunity to the treatment.
