Abstract
The disclosure provides compositions and methods for making a colorized solution of an aqueous disinfectant that is both stable in bulk solution and will fade to clear within a predetermined period of time after being applied to a surface, for example as a spray or film. The compositions and methods described here allow an end user to visualize both the extent of coverage and the duration of contact of the disinfectant with the surface, thereby providing more efficient disinfection of the surface.
