PURPOSE: Antimicrobial cleaning compositions containing aromatic alcohols or phenols are provided, which are characterized by high kill of bacteria and removal soil so as to retard reinfection and regrowth of bacterial populations. CONSTITUTION: The invention relates to the use of an optionally substituted aromatic alcohols or phenols, other than phenol per se, of the general formula: HO.R1.Aryl(R2)n wherein R1 is absent or is C1-C6 alkyl, alkenyl or alkoxy, R2 is absent or one or more ring substituents selected from C1-C6 alkyl, alkenyl or alkoxy, and n is 0-5, as a biocidal activity improving additive in a non-abrasive cleaning composition of pH below 6 or above 8 which comprises 0.1-30 wt.% of an ethoxylated alkanol nonionic surfactant with an HLB of 9-14. The invention also relates to compositions comprising 0.15-15 wt.% of the phenol or alcohol and to a method of cleaning a surface which involves the step of treating the surface with such a composition.
