Alkali metal carbonate-based cleaning compositions and methods of both making and using the same provide user-friendly, solid, detergent compositions without the need for using a separate rinse aid composition. The compositions and methods are particularly well suited for use in industrial cleaning using alkali metal carbonate compositions that beneficially provide cleaning and rinseability in the rinse cycle. ## Claims ### Claim 1 An alkaline detergent and rinsing composition comprising: an alkalinity source comprising an alkali metal carbonate; a nonionic surfactant comprising a C12-C14 alcohol alkoxylate having between about 3 and about 8 moles of ethylene oxide and between about 2 and about 6 moles of propylene oxide; a builder; and from about 0.01 wt. % to about 0.5 wt. % of a corrosion inhibitor; wherein said composition performs both a cleaning and rinsing function; wherein the composition is substantially free of phosphorous, aminocarboxylates, and also substantially free of cationic and/or anionic surfactants. ### Claim 2 (depends on 1) The composition of claim 1, wherein said alkalinity source is present from about 10 wt-% to about 90 wt-%, wherein said nonionic surfactant is present from about 0.1 to about 80 wt-%. ### Claim 3 (depends on 1) The composition of claim 1, wherein the nonionic surfactant is a C12-C14 alcohol alkoxylate. ### Claim 4 (depends on 1) The composition of claim 1, wherein said composition provides substantially similar cleaning and rinsing performance as separate detergent and rinse aid compositions. ### Claim 5 (depends on 1) The composition of claim 1, further comprising a neutralizing agent in an amount between 0.1 wt-% and about 50 wt-%. ### Claim 6 (depends on 5) The composition of claim 5, wherein the alkalinity source comprises an alkali metal carbonate, wherein the alkalinity source is substantially free of alkali metal hydroxide, and wherein the neutralizing agent comprises up to about 10 wt-% alkali metal hydroxide. ### Claim 7 (depends on 1) The composition of claim 1, further comprising an enzyme wherein the enzyme is a protease, lipase and/or amylase. ### Claim 8 (depends on 1) The composition of claim 1, further comprising an alkyl alkoxylate. ### Claim 9 (depends on 8) The composition of claim 8, wherein the alkyl alkoxylate is present from about 0.1 wt-% to about 15 wt-%. ### Claim 10 A method of cleaning and rinsing ware comprising: contacting ware with an alkaline detergent composition comprising an alkalinity source comprising an alkali metal carbonate, from about 0.01 to about 0.5 wt. % of a corrosion inhibitor, and a nonionic surfactant, wherein said nonionic surfactant comprises a C12-C14 alcohol alkoxylate having between about 3 and about 8 moles of ethylene oxide and between about 2 and about 6 moles of propylene oxide; wherein the composition is substantially free of phosphorous, aminocarboxylates, and also substantially free of cationic and/or anionic surfactants; rinsing said ware with water; wherein no separate rinse aid composition is employed in the method, and wherein said alkaline detergent composition provides at least substantially similar cleaning and rinsing performance as separate detergent and rinse aid compositions. ### Claim 11 (depends on 10) The method of claim 10, wherein said alkalinity source is present from about 10 wt-% to about 90 wt-%, and wherein said nonionic surfactant is present from about 0.1 wt-% to about 80 wt-%. ### Claim 12 (depends on 10) The method of claim 10, wherein the nonionic surfactant is a C12-C14 alcohol alkoxylate. ### Claim 13 (depends on 10) The method of claim 10, wherein the alkaline detergent composition further comprises a neutralizing agent in an amount between about 0.1 wt-% and about 50 wt-%. ### Claim 14 (depends on 13) The method of claim 13, wherein the alkalinity source comprises an alkali metal carbonate, wherein the alkalinity source is substantially free of alkali metal hydroxide, and wherein the neutralizing agent comprises up to about 10 wt-% alkali metal hydroxide. ### Claim 15 (depends on 10) The method of claim 10, wherein the alkaline determine composition further comprises a protease, lipase and/or amylase enzyme. ### Claim 16 (depends on 10) The method of claim 10, further comprising an alkyl alkoxylate present from about 0.1 wt-% to about 15 wt-%. ### Claim 17 A solid, alkaline detergent composition comprising: between about 25 wt-% and about 80 wt-% of an alkali metal carbonate; between about 5 wt-% and about 40 wt-% of a builder; between about 1 wt-% and about 10 wt-% of a nonionic surfactant comprising a C12-C14 alcohol alkoxylate having between about 3 and about 8 moles of ethylene oxide and between about 2 and about 6 moles of propylene oxide; and between about 0.01 wt. % and about 0.5 wt. % of a corrosion inhibitor; wherein the composition is used to clean and rinse wares without the use of an additional rinse aid composition; and wherein the composition is substantially free of phosphorous, aminocarboxylates, and also substantially free of cationic and/or anionic surfactants. ### Claim 18 (depends on 17) The composition of claim 17, further comprising an alkyl alkoxylate. ### Claim 19 (depends on 17) The composition of claim 17, further comprising an enzyme. ### Claim 20 (depends on 17) The composition of claim 17, wherein the solid, alkaline detergent is a cast, extruded, or pressed solid.
