Abstract:
1. A method for cleaning waste treatment system components, medical instruments surfaces or enzyme residue-containing surfaces comprising: applying to a surface to be cleaned a composition devoid of an antifoam agent and enzymatic cleaning agent comprising (A) a residue cleaning agent selected from the group consisting of sodium lauryl sulfate, sodium lauryl ether sulfate, ammonium lauryl sulfate, ammonium lauryl ether sulfate, sophorose biosurfactant, sodium lauroyl sarcosinate, triethanolamine lauroyl-L-glutamate, sodium myristyl sarcosinate, sodium dodecyl sulfate, potassium laurate, sodium dodecane sulfonates, and sodium lauryl ethoxysulfate and (B) a substantially non-water soluble nonionic surfactant having an initial Ross-Miles foam height in an aqueous solution at 25° C. of less than 10 millimeters, wherein a weight ratio of residue cleaning agent to surfactant on 100 wt. % active ingredient basis ranges from about 0.05:1 to about 0.5:1, wherein the amount of composition sprayed onto the surface is sufficient to effectively clean and remove residue from the surface; and rinsing the surface with purified water to remove the composition from the cleaned surface.
