摘要

The present invention relates to a method for cleaning an object comprising the steps: (a) distributing to the object a first soak solution comprising at least one surfactant and at least one enzyme followed by a first soak period wherein the concentrations of the at least one surfactant and the at least one enzyme are higher relative to their concentrations in a subsequent wash solution; (b) adding to the object a second soak solution comprising at least one component that is different from any of the components comprised in the soak solution of (a) followed by a second soak period; (c) furthermore adding to the object water to obtain a wash solution followed by a wash period; and (d) rinsing the object; wherein step (b) is conducted either before or after step (c), and wherein said method has a wash performance corresponding to any of (i) a Relative Wash Performance (RWP) of at least 1; (ii) a Process Related Cleaning Index (PRCI) of more than 1; or (iii) a Relative Wash Performance (RWP) of at least 1 and a Process Related Cleaning Index (PRCI) of more than 1.
