A medical surface cleaning composition and a method for cleaning waste treatment system components, medical instruments surfaces, and enzyme residue-containing surfaces. The composition includes a residue cleaning agent and 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. 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, and wherein the residue cleaning agent and surfactant are biodegradable.

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; andrinsing the surface with purified water to remove the composition from the cleaned surface. 2. The method of claim 1, wherein the weight ratio of residue cleaning agent to surfactant in the composition on 100 wt. % active ingredient basis ranges from about 0.075:1 to about 0.3:1. 3. The method of claim 1 wherein the surfactant comprises a polyether polyol non-ionic surfactant having an initial Ross-Miles foam height in an aqueous solution at 25° C. of less than 5 millimeters. 4. The method of claim 1, wherein the composition has a total active ingredient concentration ranging from about 0.25 wt. % to about 10 wt. %. 5. The method of claim 1, wherein the composition has a total active ingredient concentration ranging from about 0.5 wt. % to about 5 wt. %. 6. A method for removing enzyme residue from 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; andrinsing the surface with purified water to remove the composition from the cleaned surface. 7. The method of claim 6, wherein the weight ratio of residue cleaning agent to surfactant in the composition on 100 wt. % active ingredient basis ranges from about 0.075:1 to about 0.3:1. 8. The method of claim 6 wherein the surfactant comprises a polyether polyol non-ionic surfactant having an initial Ross-Miles foam height in an aqueous solution at 25° C. of less than 5 millimeters. 9. The method of claim 6, wherein the composition has a total active ingredient concentration ranging from about 0.25 wt. % to about 10 wt. %. 10. The method of claim 6, wherein the composition has a total active ingredient concentration ranging from about 0.5 wt. % to about 5 wt. %.
