1. An anti-microbial composition comprising:

  • a given amount of a given surfactant selected from the group consisting of 0.6%, 1%-4%, 6% and 10% of a poloxamer L-31, 0.6%, 3%, 4% and 6% of a poloxamer L-43, 3% of a poloxamer L-61, 2%, 3% and 4% of a poloxamer L-121, 0.1% of a poloxamer F-38, 6% of a poloxamer F-87, 2% of a poloxamer F-127 and 6% octylphenol ethoxylate 7.5, the poloxamer L-31 including an approximate molecular weight of propylene oxide/ethylene oxide block copolymer of 1100, an approximate molecular weight of the propylene oxide block of 950, and approximately 10% ethylene oxide content in the propylene oxide/ethylene oxide block copolymer, the poloxamer L-43 including an approximate molecular weight of propylene oxide/ethylene oxide block copolymer of 2500, an approximate molecular weight of the propylene oxide block of 1750, and approximately 20% ethylene oxide content in the propylene oxide/ethylene oxide block copolymer, the poloxamer L-61 including an approximate molecular weight of propylene oxide/ethylene oxide block copolymer of 2000, an approximate molecular weight of the propylene oxide block of 1750, and approximately 10% ethylene oxide content in the propylene oxide/ethylene oxide block copolymer, the poloxamer L-121 including an approximate molecular weight of propylene oxide/ethylene oxide block copolymer of 4400, an approximate molecular weight of the propylene oxide block of 4000, and approximately 10% ethylene oxide content in the propylene oxide/ethylene oxide block copolymer, the poloxamer F-38 including an approximate molecular weight of propylene oxide/ethylene oxide block copolymer of 5000, an approximate molecular weight of the propylene oxide block of 950, and approximately 80% ethylene oxide content in the propylene oxide/ethylene oxide block copolymer, the poloxamer F-87 including an approximate molecular weight of propylene oxide/ethylene oxide block copolymer of 7700, an approximate molecular weight of the propylene oxide block of 2250, and approximately 70% ethylene oxide content in the propylene oxide/ethylene oxide block copolymer, the poloxamer F-127 including an approximate molecular weight of propylene oxide/ethylene oxide block copolymer of 12500, an approximate molecular weight of the propylene oxide block of 4000, and approximately 70% ethylene oxide content in the propylene oxide/ethylene oxide block copolymer;

    citric acid;

    hydrogen peroxide; and

    peracetic acid;

    wherein the citric acid;

    hydrogen peroxide;

    peracetic acid ratio is equivalent to 0.7-3 citric acid;

    0.7-3 hydrogen peroxide;

    1-1.4 peracetic acid by weight; and

    the composition is not corrosive to ferrous metal after at least 2 hours of contact with the metal.
