Claim:
A wipe for use in removing bacteria from a surface, the wipe comprising a nonwoven web that includes absorbent fibers, the web being treated with at least one bacteriostatic agent and at least one zwitterionic solvatochromatic indicator, wherein the bacteriostatic agent includes an aluminum chlorohydrate having cations with an affinity for the negatively charged cell walls of the bacteria that enables the bacteriostatic agent to capture bacteria from the surface, wherein the bacteriostatic agent is applied to a surface of the wipe, wherein the indicator is applied over the bacteriostatic agent, and wherein the indicator is present on a surface of the wipe in a pattern that covers from 5% to 95% of the surface so that a visible pattern is detectable in the presence of the bacteria, wherein the detected visible pattern signals to a user that the bacteriostatic agent is capturing bacteria.
