1. A method for disinfecting a surface in need of disinfecting within a volumetric space, comprising the steps of:
(a) dispersing into the volumetric space a multiplicity of droplets of a first aqueous composition comprising a first peracid reactant compound that is either a peroxide compound or an organic acid compound, wherein an amount of the dispersed first aqueous composition is sufficient to provide a coalesced layer of the first aqueous composition upon the surface with a substantially uniform thickness of at least about 1 micron, and up to about 20 microns;
(b) dispersing into the volumetric space a multiplicity of droplets of a second aqueous composition comprising a second peracid reactant compound that is the other of the first peracid reactant compound, wherein an amount of the dispersed second aqueous composition is sufficient to provide a coalesced layer of the second aqueous composition upon the surface with a substantially uniform thickness of at least about 1 micron, and up to about 20 microns; and
c) coalescing the multiplicity of droplets of the first aqueous composition and the multiplicity of droplets of the second aqueous composition upon the surface to form a reaction layer upon the surface, thereby forming a peracid in situ within the reaction layer and disinfecting the surface;
wherein at least one of the first aqueous composition or the second aqueous composition further comprises one or more alcohols, wherein the total weight of the one or more alcohols relative to the weight of the aqueous composition is between about 0.05% and about 70% by weight.
