6. The removable cartridge according to claim 2 , wherein the colorant is an acid dye.
7. The removable cartridge according to claim 6 , wherein the acid dye is an acid green dye.
8. The removable cartridge according to claim 1 , wherein the catalyst is an oxidizing agent.
9. The removable cartridge according to claim 8 , wherein the oxidizing agent is selected from peracetic acid, sodium perchlorate, hydrogen peroxide, and bismuth silver oxide.
10. The removable cartridge according to claim 9 , wherein the oxidizing agent is hydrogen peroxide.
11. The removable cartridge according to claim 1 , wherein the third chamber comprises the additive.
12. The removable cartridge according to claim 11 , wherein at least one of the one or more additives is a pH modulator.
13. The removable cartridge according to claim 12 , wherein the pH modulator is an alkaline base.
14. The removable cartridge according to claim 1 , wherein the third chamber comprises the further catalyst.
15. The removable cartridge according to claim 14 , wherein the further catalyst is a metal salt.
16. The removable cartridge according to claim 15 , wherein the metal salt is selected from iron, copper, zinc, or magnesium salt.
17. The removable cartridge according to claim 16 , wherein the metal salt is a copper salt.
18. The removable cartridge according to claim 1 , wherein the third chamber comprises the additive and the further catalyst.
19. The removable cartridge according to claim 18 , wherein at least one of the one or more additives is a pH modulator.
20. The removable cartridge according to claim 19 , wherein the pH modulator is an alkaline base.
21. The removable cartridge according to claim 18 , wherein the further catalyst is a metal salt.
22. The removable cartridge according to claim 21 , wherein the metal salt is selected from iron, copper, zinc, or magnesium salt.
23. The removable cartridge according to claim 22 , wherein the metal salt is a copper salt.
24. The removeable cartridge according to claim 18 , wherein the additive is selected from a surfactant, polymer, or a humectant and the further catalyst is a copper salt.
25. The removable cartridge according to claim 1 , wherein the disinfectant wipe is a quaternary ammonium based disinfectant wipe or a hydrogen peroxide based disinfectant wipe.
26. A removable cartridge configured to be coupled to a device for applying a multi-component indicator composition to a disinfectant wipe dispensed through the device, the removable cartridge comprising:
a cartridge housing defining a reservoir; and
a penetrable barrier extending through a portion of the cartridge housing;
wherein the reservoir comprises 3 chambers sized to contain a separate component of the multi-component indicator composition,
wherein a first chamber comprises a first composition comprising a colorant selected from a triarylmethane dye, an azo dye, an indigoid dye, an acid dye or a basic dye, a second chamber comprises a second composition comprising hydrogen peroxide, and a third chamber comprises a third composition comprising an alkaline base and/or a copper salt.
27. The removable cartridge according to claim 26 , wherein the colorant is a triarylmethane dye.
28. The removable cartridge according to claim 26 , wherein the colorant is an indigoid dye.
29. The removable cartridge according to claim 28 , wherein the indigoid dye is indigo carmine.
30. The removable cartridge according to claim 26 , wherein the colorant is an acid dye.
31. The removable cartridge according to claim 30 , wherein the acid dye is an acid green dye.
32. The removable cartridge according to claim 26 , wherein the third component comprises an alkaline base.
