Cleaning of a cooking device or appliance with a composition comprising a built-in rinse aid
View Patent ↗The present invention discloses a method for cleaning a cooking device or appliance comprising contacting at least the cooking chamber of the cooking device or appliance with a cleaning composition comprising a sheeting polymer that provides a layer on the surfaces of at least the cooking chamber so as to afford a sheeting action in an aqueous rinse step. The sheeting polymer is selected from the group of cationic polysaccharides and maleic acid-olefin copolymers.
1. A method for cleaning an oven comprising contacting at least the cooking chamber of the oven with a cleaning composition comprising a sheeting polymer that provides a layer on the surfaces of at least the cooking chamber so as to afford a sheeting action of water over the cooking chamber in an aqueous rinse step with water, the water free of a rinse aid and a descaling agent, followed by rinsing at least the cooking chamber with the water,
wherein the sheeting polymer is (3-Chloro-2-Hydroxypropyl) Trimethylammonium Chloride modified starch.
2. A method for cleaning an oven comprising contacting at least the cooking chamber of the oven with a cleaning composition comprising a sheeting polymer that provides a layer on the surfaces of at least the cooking chamber so as to afford a sheeting action of water over the cooking chamber in an aqueous rinse step, wherein the sheeting polymer is a maleic acid-di-isobutylene copolymer having the formula
wherein L 1 is hydrogen or sodium, R 1 and R 3 are hydrogen, R 2 is methyl, R 4 is neopentyl, x is 1, and y is 1.
3. The method according to claim 1 , wherein the step of rinsing occurs prior to drying the cooking chamber.
4. The method according to claim 1 , wherein the cleaning composition is in the form of a powder, granulated powder, tablet, solid block, aqueous solution, emulsion, structured liquid or gel.
5. The method according to claim 1 , wherein the cleaning composition is a powder and/or a granulate and is packed in a sachet of a water-soluble polymer.
6. The method according to claim 1 , wherein the sheeting polymer constitutes 1 to 5% (w/w), based on total (wet or dry) weight of the composition.
7. The method according to claim 1 , wherein the concentration of the sheeting polymer in an aqueous cleaning solution obtainable by diluting or dissolving the cleaning composition in water is from 20 to 300 ppm.
8. The method according to claim 1 , wherein the contacting is done manually and/or automatically.
9. The method according to claim 8 , wherein the contacting is done by spraying, fogging, wiping and/or circulating the cleaning composition or a cleaning solution obtained by diluting or dissolving the cleaning composition in water in at least the cooking chamber of the oven.
10. The method according to claim 1 , wherein the number of spots on a steel surface of the cooking chamber cleaned by the cleaning composition is reduced by a factor of at least about 24 as compared to the steel surface of the cooking chamber cleaned by the cleaning composition without the sheeting polymer.
