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.

1. A method of making a peracid composition, the method comprising: combining a first aqueous solution and a second aqueous solution, wherein:the first aqueous solution comprises (A) about 0.05% to about 10% by weight polyvinyl alcohol, (B) 3% to about 20% by weight of an organic carboxylic acid sel
1. A method of making a peracid composition, the method comprising: combining a first aqueous solution and a second aqueous solution, wherein:the first aqueous solution comprises (A) about 0.05% to about 10% by weight polyvinyl alcohol, (B) 3% to about 20% by weight of an organic carboxylic acid selected from the group consisting of citric acid, acetic acid, and combinations thereof, and (C) 10 ppm to about 1,000 ppm by weight colloidal transition metal particles selected from the group consisting of colloidal silver metal particles, colloidal silver alloy particles, and combinations thereof; andthe second aqueous solution comprises 0.5% to about 10% by weight of an activator selected from the group consisting of hydrogen peroxide, methyl ethyl ketone peroxide, carbamide peroxide, potassium superoxide, lithium peroxide, barium peroxide, sodium peroxide, calcium peroxide, strontium peroxide, magnesium peroxide, sodium percarbonate, sodium peroxide, potassium peroxide, and combinations thereof. 2. The method of claim 1, wherein the activator is hydrogen peroxide. 3. The method of claim 1, wherein the activator is magnesium peroxide. 4. The method of claim 1, wherein the activator is sodium percarbonate. 5. The method of claim 1, wherein the concentration, by weight, of the colloidal transition metal particles is from 150 ppm to 300 ppm. 6. The method of claim 4, wherein the colloidal transition metal particles are colloidal silver metal particles. 7. The method of claim 6, wherein the activator is hydrogen peroxide. 8. The method of claim 6, wherein the activator is magnesium peroxide. 9. The method of claim 6, wherein the activator is sodium percarbonate. 10. The method of claim 1, wherein the first aqueous solution comprises 7% to about 20% by weight of the organic carboxylic acid. 11. A method of making a peracid composition, the method comprising: combining a first aqueous solution and a second aqueous solution, wherein:the first aqueous solution comprises (A) about 0.05% to about 1% by weight polyvinyl alcohol, (B) 3% to about 13% by weight of an organic carboxylic acid selected from the group consisting of citric acid, acetic acid, and combinations thereof, and (C) 10 ppm to about 1,000 ppm by weight colloidal transition metal particles selected from the group consisting of colloidal silver metal particles, colloidal silver alloy particles, and combinations thereof; andthe second aqueous solution comprises 0.5% to about 10% by weight of an activator selected from the group consisting of hydrogen peroxide, methyl ethyl ketone peroxide, carbamide peroxide, potassium superoxide, lithium peroxide, barium peroxide, sodium peroxide, calcium peroxide, strontium peroxide, magnesium peroxide, sodium percarbonate, sodium peroxide, potassium peroxide, and combinations thereof. 12. The method of claim 11, wherein the activator is hydrogen peroxide. 13. The method of claim 11, wherein the activator is magnesium peroxide. 14. The method of claim 11, wherein the activator is sodium percarbonate. 15. The method of claim 11, wherein the concentration, by weight, of the colloidal transition metal particles is from 150 ppm to 300 ppm. 16. The method of claim 15, wherein the colloidal transition metal particles are colloidal silver metal particles. 17. The method of claim 16, wherein the activator is hydrogen peroxide. 18. The method of claim 16, wherein the activator is magnesium peroxide. 19. The method of claim 16, wherein the activator is sodium percarbonate. 20. The method of claim 11, wherein the first aqueous solution comprises 7% to about 20% by weight of the organic carboxylic acid.
