Abstract
A cleaning composition for treating a surface comprises a purified enzyme and an enzyme denaturant system. The enzyme denaturant system is configured to denature the purified enzyme such that any residue remaining on the surface after the treatment of the surface is virtually free of active purified enzymes.
Claims6
A kit for application of a cleaning composition to a surface to be treated comprising:
- a package comprising:
- a first compartment and a second compartment;
- a first composition comprising at least one purified enzyme stored in the first compartment;
- and
- a second composition comprising bacterial spores stored in the second compartment, separate from the first composition, wherein the bacterial spores are adapted to produce an enzyme denaturant;
- wherein when the first composition and the second composition are mixed during application of the cleaning composition to the surface, the enzyme denaturant produced by the bacterial spores denatures the at least one purified enzyme to decrease a concentration of the at least one purified enzyme in residue remaining on the surface after application of the cleaning composition to the surface;
- and wherein the kit further comprises a dispensing system configured to dispense the first composition from the first compartment and the second composition from the second compartment such that the first composition and the second composition mix as the first and second compositions are dispensed from their respective first and second compartments or as the first and second compositions are applied to the surface.
