Abstract:
1. A method for removing one or more soils from a surface comprising the steps of: A) formulating a cleaner from a sufficient amount of cleaner concentrate and water, the cleaner concentrate comprising: i) one or more alkalinity sources selected from the group consisting of alkanolamines, alkali metal hydroxides, alkali metal carbonates, and alkali metal silicates present in an amount sufficient to provide a free alkalinity (expressed as Na ii) disodium ethanoldiglycine present in an amount of at least about 6 wt sufficient to permit a use of a water having a hardness number up to about 600 ppm (600 mg/L) and to maintain the concentrate in a single phase; iii) from about 4 wt % to about 15 wt % of a surfactant system comprising an alkyl sulfate, alcohol ethoxylate, and an alkyl amphoacetate mixture; and iv) the remainder to 100 wt % of water, based on the total weight of the cleaner concentrate; B) communicating the cleaner with the soiled surface wherein the one or more soils originate from a polymerized fat and/or oil comprising one of a low trans-fat fat or oil or a non-trans-fat fat or oil having an iodine value from about 38 to about 132 calculated, using the formula: for at least a sufficient amount of time to allow the cleaner to interact with the soil of the soiled surface; C) removing any residue from the surface thereby cleaning the surface.
