摘要： A method for cleaning medical equipment by scrubbing the equipment with an open-cell melamine-formaldehyde foam comprising an antibacterial active composition, and wherein the open-cell melamine-formaldehyde foam is prepared from a melamine-formaldehyde precondensate, wherein the molar ratio melamine to formaldehyde of the melamine-formaldehyde precondensate is smaller than 0.5.
