Two-part disinfectant system and related methods

Abstract

The present disclosure is drawn to a disinfectant system which can be used to disinfect surfaces. The system includes a first chamber containing a first solution and a second chamber containing a second solution. The first solution can include an alcohol, an organic carboxylic acid, and from 0.01 ppm, to 1,000 ppm by weight of a transition metal or alloy thereof based on the first solution weight content. The second solution can include hydrogen peroxide. The system further includes a dispenser through which the system is configured to mix and dispense the first solution and the second solution immediately before being dispensed. A peracid composition is formed upon mixing of the first and second solutions.
