Cleaner concentrates, associated cleaners, and associated methods are
disclosed. The cleaner concentrates are capable for use in making
cleaners that are capable of removing from surfaces fresh, greasy soils
and polymerized soils more recently encountered in the food service
industry originating from non-trans-fat oils. The cleaner concentrates
include one or more alkalinity sources, one or more chelants, one or more
surfactants, and as a remainder, water. The one or more alkalinity
sources may be present in an amount sufficient to provide a free
alkalinity (expressible as Na.sub.2O) of greater than about 3.6 wt % and
a total alkalinity (expressible as Na.sub.2O) of greater than about 6.1
wt %, based on the total weight of the cleaner concentrate. The one or
more chelants may be present in an amount sufficient to permit a use of a
water having a hardness number up to about 600 ppm (600 mg/L) or more.
