The invention provides a reversibly protected colorant or a composition thereof which when mixed with a disinfectant solution imparts color to the disinfectant solution allowing for temporary visualization of a disinfectant, and methods for use in the disinfection, decontamination, and/or cleaning of surfaces, objects. The reversibly protected colorant or composition thereof is added to a disinfectant solution or disinfectant article (e.g., disinfectant wipe, microfiber, rag, towel, cloth, spun-woven wipes, nonwoven wipes, etc.), wherein the reversibly protected colorant or a composition thereof imparts color to the disinfectant solution resulting in a colored disinfectant solution until such protection is removed, thereby releasing the colorant and exposing the colorant to an agent and/or oxidizing conditions that cause the colorant to permanently lose its color. The invention also provides methods of using the colored disinfectant solutions for visually indicating surface disinfection and the method of visually indicating surface disinfection.
