Abstract
Cleaner compositions, associated cleaners, and associated methods are disclosed. The cleaner compositions are capable for use in making thickened cleaners that are capable of removing from vertical and inverted surfaces fresh, greasy soils and baked-on soils encountered in the food service industry. The cleaner compositions include one or more alkalinity sources, one or more chelants, one or more surfactants, one or more thickening agents, one or more buffers, and as a remainder, water. Cleaner compositions of the invention are substantially free of phosphates and have a low caustic content making them user and environmentally friendly. Yet the cleaners of the invention are surprisingly effective at removing tenacious baked-on soils encountered in the food service industry. Compositions of the invention have a viscosity of about 700 cps and are applied using a foaming or misting dispenser. The one or more alkalinity sources may be present in an amount sufficient to provide a free alkalinity (expressible as NaO) of less than about 1.0 wt % and a total alkalinity (expressible as NaO) of less than about 2.0 wt %, based on the total weight of the cleaner concentrate. The one or more chelants may be present in an amount up to about 5.0 wt %.
