The present invention comprises chlorinated and non-chlorinated alkaline cleaning compositions for removal of proteinaceous and fatty soils at low temperature, i.e. less than 120 F., with little or no deleterious affect on cleaning performance. According to the invention, applicants have found that adding additional alkalinity makes protein removal more difficult and reducing the amount of alkalinity actually improves performance. According to the invention optimized combinations of chlorine and alkalinity components for low temperature cleaning as well as a surfactant system optimized for low temperature fatty soil removal are disclosed.

A composition includes methyl acetate, dimethyl carbonate, acetone, or a combination thereof, dimethyl sulfoxide, methyl glyoxal, propylene carbonate, gamma butyrolactone, ethylene carbonate, 2-chloro-1-propanol, or a combination thereof, and optionally thiophene, 1,3-dioxolane, thioacetic acid, or a combination thereof. The respective amounts of each solvent are further described herein, and the total amounts of methyl acetate, dimethyl carbonate, acetone, dimethyl sulfoxide, methyl glyoxal, propylene carbonate, thiophene, 1,3-dioxolane, and thioacetic acid sum to at least 90 volume percent of the total volume of the composition. The composition can be particularly useful for removal of a coating from a surface. Accordingly, a method of removing a coating from a surface is also disclosed.

An azeotropic composition a formulated with 1,1,1,3,3,3,-hexafluoro-2-methoxypropane and a second component selected from the group consisting of isopropyl alcohol, ethanol, methanol, and trans-1,2-dichloroethylene. The azeotropic composition exhibits a substantially constant boiling point at a constant pressure and is useful for various cleaning and degreasing applications.

A cleaning formulation includes water in an amount in the range of about 95 to about 99 weight percent, non-volatile polyols in an amount in the range of about 0.1 to about 3.0 weight percent, and surfactant in an amount in the range of about 0.001 to about 2.0 weight percent. The surfactant is not limited to non-ionic surfactants and the ingredients are derived from natural sources or food-grade materials.
