Synergistic cleaning disinfectant solution with enhanced stability, and methods of using the same

Abstract

A method of cleaning and disinfecting a surface comprises producing a diluted cleaning disinfectant solution from a concentrated cleaning disinfectant solution, and contacting the surface with the diluted solution. A concentrated cleaning disinfectant solution is stable at freezing temperatures and comprises antimicrobial acid, surface cleaning acid, solubilizing agent, hydrotrope, and surfactant. The antimicrobial acid comprises a synergistic combination of (i) salicylic acid, derivative of salicylic acid, or a combination thereof, and (ii) gluconic acid, derivative of salicylic acid, or a combination thereof. The surface cleaning acid comprises at least one acid selected from mineral acid, methane sulfonic acid, formic acid, or sulfonic acid having an alkyl group with no greater than three carbon atoms. The surfactant selected from anionic surfactant, non-ionic surfactant, or a mixture thereof.
