US Patent No. 8,999,911 B2; Bissell Homecare has patented a kit for application of a cleaning composition. It is comprised of a package comprising: a first and second compartments; 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. 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 purified enzyme to decrease a concentration of the purified enzyme in residue remaining on the surface after application of the cleaning composition. The kit also has a dispensing system.
