Claims
- 1. A process for removing oily, greasy, or waxy soil from an aluminum surface, said process comprising steps of:(I) contacting the aluminum surface at a pH within the range of 4.5-6 with an aqueous liquid composition that is free of silicates and comprises: (A) an amine oxide surfactant; and (B) a component selected from the group consisting of molecules, exclusive of molecules that are part of component (A), that include a moiety corresponding to general chemical formula I: whereR represents a monovalent aliphatic moiety with the chemical formula —CnH(2n+1−y)Fy, wherein n is an integer from 6 to 22, and y is an integer from 0 to (2n+1) for a sufficient time at a sufficient temperature with sufficient relative motion between the aluminum surface and the aqueous liquid composition to transfer at least part of the oily, greasy, or waxy soil from the metal surface to suspension or solution in the aqueous liquid composition.
- 2. A process for removing oily, greasy, or waxy soil from an aluminum metal surface, said process comprising steps of:contacting the aluminum metal surface at a pH within the range of 4.5 to 6 with an aqueous liquid composition that is free of silicates and comprises: (A) a component selected from the group consisting of: (A.1) amine oxide surfactants; and (A.2) nonionic surfactants, other than amine oxide surfactants, said nonionic surfactants having a hydrophile-lipophile balance (HLB) value from about 9.6 to about 16 and which contain a moiety conforming to the chemical formula -(CmH(2m-z)XzO)v-, whereinm has the value 2, 3, or 4; z represents an integer with a value from 0 to 2m; x represents a halogen atom, and if z has a value of more than 1, may represent the same or a different halogen atom for each x; and v represents a positive integer; and (B) a component selected from the group consisting of molecules, exclusive of molecules that are part of component (A), that include a moiety corresponding to general chemical formula I: whereR represents a monovalent aliphatic moiety with the chemical formula —CnH(2n+1−y)Fy, wherein n is an integer from 6 to 22, and y is an integer from 0 to (2n+1); and (C) optional alkalinizing agents; hydrotroping agents; corrosion inhibitors; and sequestering agents, for a sufficient time at a sufficient temperature with sufficient relative motion between the metal surface and the aqueous liquid composition to transfer at least part of the oily, greasy, or waxy soil from the metal surface to suspension or solution in the aqueous liquid composition.
- 3. A process for removing oily, greasy, or waxy soil from an aluminum metal surface, said process comprising steps of:(I) contacting the aluminum metal surface at a pH within the range of 4.5 to 6 with an aqueous liquid composition that is free of silicates and comprises: (A) a component selected from the group consisting of: (A.1) amine oxide surfactants; and (A.2) nonionic surfactants, other than amine oxide surfactants, said nonionic surfactants having a hydrophile-lipophile balance (HLB) value from about 9.6 to about 16 and which contain a moiety conforming to the chemical formula -(CmH(2m-z)XzO)v-, whereinm has the value 2, 3, or 4; z represents an integer with a value from 0 to 2m; x represents a halogen atom, and if z has a value of more than 1, may represent the same or a different halogen atom for each x; and v represents a positive integer; and (B) a component selected from the group consisting of molecules, exclusive of molecules that are part of component (A), that include a moiety corresponding to general chemical formula I: whereR represents a monovalent aliphatic moiety with the chemical formula —CnH(2n+1−y)Fy, whereinn is an integer from 6 to 22, and y is an integer from 0 to (2n+1); and (C) an alkalinizing agent that is not part of any of the previously recited components; (D) a hydrotroping agent that is not part of any of the previously recited components; (E) a corrosion inhibitor that is not part of any of the previously recited components; and (F) a sequestering agent that is not part of any of the previously recited components.
