Abstract
Methods comprising the steps of contacting a surface with a liquid composition comprising a cleaning agent, an adhesion promoter, and at least one dye, the surface having a first surface contamination; transitioning at least one portion of the surface in the first surface contamination state to a second surface contamination state and simultaneously distributing the at least one dye and at least one adhesion promoter on the surface associated with the second surface contamination state, the second surface contamination state having reduced or eliminated surface contamination, the transitioning step simultaneously cleaning and preparing the at least one portion of the surface for adhesion to another material; and identifying remaining surface in the first surface contamination state, and compositions adapted for the method thereof.
