The invention relates to liquid sanitizing and/or disinfecting compositions comprising an active agent, an indicator compound, an acid, and a solvent. The compositions may be applied to a surface by spraying or transferring from cleaning article, in order to eliminate pathogens on the surface. The indicator compound may comprise a dye such as a cyanine dye, which provides a color to the composition and has at least one absorption maxima in the visible region. Once applied to the surface, the composition undergoes a color transition and becomes colorless.

The invention comprises a method for treating a pathogen, comprising the steps of: reacting, in a solution, a poly(2-alkyl-2-oxazoline) with a strong acid to form a polyalkylenimine and a carboxylic acid, the polyalkylenimine comprising protonated sites, wherein a pendant in the poly(2-alkyl-2-oxazoline) comprises the 2-alkyl group in poly(2-alkyl-2-oxazoline); increasing relative concentration of the polyethylenimine through removal of at least 2% and less than 97% of the carboxylic acid from the solution; adjusting pH of the solution to greater than 2.5; forming a film on a substrate from the solution; contacting first bacteria with the film; and reducing activity of the first bacteria contacting the film by: greater than 9% and less than 99.99995% in less than one minute; greater than 99.999% in less than four days; and greater than 99.99995% in less than seven days.
