    摘要： A method for increasing the visibility of a disinfectant solution applied to a surface or an object is disclosed. The method comprises providing a disinfectant solution and providing an aqueous composition comprising a surfactant and a water-soluble pigment, which may be a water-soluble oxidizable dye. The surface or object is treated with the disinfectant solution and the aqueous composition, which may disinfect the surface or object. The pigment initially expresses a color to provide visual confirmation of treated areas and fades to clear over time, which may indicate that a sufficient amount of time has passed for adequate decontamination and may avoid staining treated surfaces. The period of time may be 3 to 30 minutes, optionally from 3 to 10 minutes, or up to 15 minutes. The disinfectant solution may be an aqueous bleach solution. The disinfectant solution may comprise one or more disinfectants selected from sodium hypochlorite, calcium hypochlorite, hydrogen peroxide, peracetic acid and benzalkonium chloride. The surfactant may be selected from sodium dodecyl sulfate, sodium dodecylbenzenesulfonate, hexadecyltrimethylammonium bromide and sodium 3,4-dichlorobenzoate. The composition may comprise a thickening agent and/or an alkaline builder and/or a hydrotrope. The disinfectant solution and the aqueous solution may be suitable for use with any spray device, which may be a contractor spray or spray bottle.
