Patent attributes
A method for cleaning contaminated surfaces of surgical waste management equipment. The method includes rinsing surfaces of the equipment with water to remove water soluble contaminants and waste material. A rinse solution is applied to the surfaces of the equipment to provide a residual film thereon. The rinse solution includes a first nonionic nonylphenol surfactant having an HLB value ranging from about 10 to about 15, a second nonionic nonylphenol surfactant having an HLB value ranging from about 16 to 20, a bio-film permeation agent, and an aqueous solvent. A total of the first surfactant and the second surfactant in the solution ranges from about 2 to about 20 percent by weight of a total weight of the solution and a ratio of the second surfactant to the first surfactant in the solution ranges from about 2:1 to about 4:1.
