    摘要: A shelf-stable concentrated antimicrobial composition and method of using same comprises: at least one cyclic carboxylic acid and/or salt thereof in an amount from about 1 wt. % to about 10 wt. %; at least one anionic surfactant in an amount from about 10 wt. % to about 35 wt. %; at least one non-surfactant strong acid having a pKa less than about 2.3 in an amount from about 2 wt. % to about 25 wt. %; and at least one chelating agent in an amount from about 0.1 wt. % to about 10 wt. %. The composition retains at least 90% of its original antimicrobial efficacy after storage for at least five years at room temperature, and is substantially free of hydrogen peroxide, sources of hydrogen peroxide, parabens, aldehydes, aldehyde releasing agents, phenols, biguanides, peroxycarboxylic acids, quaternary ammonium compounds, chlorine compounds, enzymes, and etchants.
