1. An anti-microbial film-forming composition comprising:
between about 1500 ppm to about 3906 ppm of a quaternary ammonium compound comprising an alkyl dimethyl quaternary ammonium chloride;
between about 156 ppm to about 1250 ppm of a cationic biocide comprising polyhexamethylene biguanide (PHMB), wherein the ratio of cationic biocide to quaternary ammonium is from about 1:0.625 to about 1:10 on an actives weight basis;
an amine oxide surfactant in a ratio of quaternary ammonium compound to surfactant of about 2:1 to about 7:1;
a chelant comprising EDTA in a ratio of quaternary ammonium compound to chelant of about 2:1 to about 3.5:1;
wherein the chelant and surfactant are in a ratio of about 1:1 to about 2:1 by weight; and
wherein the composition forms a film on a surface and provides a residual antimicrobial effect.
