Abstract
The present disclosure is directed to antimicrobial compositions comprising a hypochlorite salt, a copper (II) salt, and an optionally acid that is an inorganic acid, an organic acid, or a combination thereof, and optionally a buffering agent, and having a chlorine concentration of between 0.1 ppm and 300 ppm and a copper (II) concentration of between 0.1 ppm and 300 ppm. Methods of making and using these compositions is also described.

A method comprising
- adding a copper (II) salt;
- and optionally an acid that is an inorganic acid, an organic acid, or a combination thereof to a first aqueous solution comprising a hypochlorite salt;
- to produce a second aqueous solution comprising the hypochlorite salt, the copper (II) salt, and optionally the acid, the second aqueous solution having a pH below 7 at 25° C., a chlorine concentration of 0.1 to 300 ppm, and a copper (II) concentration of 0.1 to 300 ppm;
- and
- the second aqueous solution contacting a surface.
