Methods and compositions for cleaning and disinfecting surfaces

An antimicrobial composition consisting essentially of

• an organic surfactant comprising a blend of C4-C24 saturated and unsaturated fatty acid salts, such that the blend comprises at least about 1-6% C6-C10 fatty acids salts, and at least about 30% C12-C14 fatty acid salts;
• an organic acid selected from the group consisting of citric acid, tartaric acid, lactic acid and malic acid;
• and
• water.

An antimicrobial composition consisting essentially of

• from about 0.5% to about 10% saponified coconut oil as the sodium or potassium salt;
• from about 1.0% to about 50% citric acid;
• and
• from about 40% to about 99% water.

An aqueous antimicrobial composition consisting essentially of

• about 2% saponified coconut oil as the sodium or potassium salt;
• about 10% citric acid;
• and
• about 88% water.

An antimicrobial solid composition consisting essentially of

• from about 0.5% to about 20% of an organic surfactant comprising
• at least 1-6% caproic, caprylic and capric acid salts, and
• at least about 30% lauric and myristic acid salts;
• and
• from about 1.0-99.5% citric acid.
