Abstract

Described is An aqueous disinfectant and hard surface cleaning composition comprising:

an effective disinfecting amount of a quaternary ammonium compound;

an effective amount of a spore forming microbial composition; and

an effective water dispersing amount of a surfactant.

The composition is used to clean a hard surface containing a diverse microbial flora. The composition cleans and disinfects by killing off undesirable microorganisms which may be causing offensive odors and leaves behind Bacillus spores which will then germinate and degrade any remaining ongoing residues without creating offensive odors.

Claims

1. An aqueous disinfectant and hard surface cleaning composition comprising:

an effective disinfecting amount of a quaternary ammonium compound;

an effective spore forming amount of a Bacillus microbial composition;

an effective water dispersing amount of a surfactant other than the quaternary ammonium compound; and

a long term stabilizing amount of a water soluble calcium ion.

3. The composition of claim 1 wherein the cleaning composition is present in the amount of 1 to 10% by wt. with the remainder of the composition being 90 to 99% by wt water.

4. The composition of claim 3 wherein the quaternary ammonium compound is present in the amount of 5.5%;

the spore forming microbial composition is present in the amount of 0.01%;

the surfactant is present in the amount of 6.3%;

and the pH ranges from 6 to 8.
