    摘要： The invention relates to methods and compositions for removing metal oxide soils from surfaces. The compositions include an anionic surfactant and a pH adjuster at an acidic pH. In one embodiment, the invention relates to a method of removing a metal oxide soil from a surface by (1) applying a use composition to the surface, the use composition having a pH adjuster in an amount sufficient to provide a use pH at or below 7, an anionic surfactant in an amount to remove a portion of the metal oxide soil, and a carrier, (2) removing the metal oxide soil from the surface with the use composition, and (3) rinsing the surface to remove the use composition and the metal oxide soil.

    摘要： The present invention relates to a liquid enzyme cleaning composition in which the enzyme is stable at alkaline pH and: at high concentration of boric acid salt; in the absence of sodium ion; and/or in the presence of at least about 40 wt-% water. In an embodiment, water is present at concentrations of at least about 60 weight percent. The present enzyme cleaning composition typically yields superior soil (especially protein soil) removal properties. In an embodiment, the composition of the invention stabilizes the enzyme with potassium and/or alkanolamine borate.
