Abstract
The invention generally relates to concentrated warewashing compositions and methods of using the same. In some aspects, the invention uses concentrated compositions in methods of warewashing where the concentrate is applied directly to the article to be cleaned, rather than dispensed into a sump and applied to the article as a ready-to-use composition. In additional aspects, the methods of using highly concentrated alkaline and/or acid compositions in an alternating pattern of alkaline-acid-alkaline or acid-alkaline-acid, or the like, provide substantially similar or superior cleaning efficacy while reducing the overall consumption of the alkaline and/or acid compositions.
