Abstract

In accordance with one aspect of the present invention, a method for cleaning a cooking chamber is provided. The method comprises applying a cleanser composition and water to the cooking chamber followed by incubating the cooking chamber. The cleanser composition comprises components that aid in loosening soil and debris during the steam cleaning and also provides a pleasant aroma. The cleanser composition aids in loosening soil and debris by effervescence.

First claim

1 . A method for cleaning a cooking chamber of an oven, comprising:
applying a cleanser composition to a soiled area on a surface of the cooking chamber and incubating the cooking chamber in the presence of saturated steam for a period of time; said cleanser composition comprising 20-70 weight percent of at least one acid, 35-50 weight percent of sodium carbonate, 0-4 weight percent of at least one fragrance, and 0-10 weight percent of at least one anti-caking agent.

2 . The method of claim 1 , the at least one acid being selected from 3-ketoglutaric acid, adipic acid, ascorbic acid, citramalic acid, citric acid, fumaric acid, glutaric acid, lactic acid, maleic acid, malic acid, malonic acid, succinic acid, tartaric acid, derivatives thereof and mixtures thereof.

3 . The method of claim 1 , further comprising at least one base being selected from calcium carbonate, magnesium carbonate, potassium carbonate, potassium bicarbonate, sodium bicarbonate, sodium percarbonate, monosodium phosphate, disodium phosphate, trisodium phosphate, tetrasodium pyrophosphate, tripotassium phosphate, phosphate-substitute salts, potassium silicate, sodium metasilicate, derivatives thereof and mixtures thereof.

4 . The method of claim 1 , the at least one fragrance being selected from natural material fragrances and synthetic aromatic agents.

5 . The method of claim 1 , the at least one anti-caking agent being selected from tricalcium phosphate, powdered cellulose, magnesium stearate, sodium bicarbonate, sodium ferrocyanide, potassium ferrocyanide, sodium silicate, silicon dioxide, calcium silicate, magnesium trisilicate, talcum powder, sodium aluminosilicate, calcium aluminosilicate, bentonite, stearic acid, polydimethylsiloxane, and derivatives thereof.

6 . The method of claim 3 , the at least one acid being citric acid and the at least one base being trisodium phosphate.

7 . The method of claim 6 , said cleanser composition comprising 37.5 weight percent citric acid, 37.5 weight percent sodium carbonate, and 25 weight percent trisodium phosphate.

8 . (canceled)

9 . The method of claim 1 , said cleanser composition comprising 50 weight percent citric acid and 50 weight percent sodium carbonate.

10 . The method of claim 6 , said cleanser composition being applied to said soiled area in solid powder form.

11 . The method of claim 10 , said chamber being incubated at 150 to 200° F. for a time period of 30 to 180 minutes, said chamber being thereafter opened so that residual, loosened soils can be removed.

12 . A method for cleaning a cooking chamber of an oven having a steam-generating device, comprising:
applying a cleanser composition to a soiled area of a cooking chamber; incubating the cooking chamber; and applying steam generated by the steam-generating device to the cooking chamber to facilitate an effervescent chemical reaction from said cleanser composition upon dissolution thereof in condensate from said steam; said cleanser composition comprising 20-70 weight percent of at least one acid, 35-50 weight percent of sodium carbonate, 0-4 weight percent of at least one fragrance, and 0-10 weight percent of at least one anti-caking agent.

13 . The method of claim 12 , the at least one acid being selected from 3-ketoglutaric acid, adipic acid, ascorbic acid, citramalic acid, citric acid, fumaric acid, glutaric acid, lactic acid, maleic acid, malic acid, malonic acid, succinic acid, tartaric acid, derivatives thereof and mixtures thereof.

14 . The method of claim 12 , further comprising at least one base being selected from calcium carbonate, magnesium carbonate, potassium carbonate, potassium bicarbonate, sodium bicarbonate, sodium percarbonate, monosodium phosphate, disodium phosphate, trisodium phosphate, tetrasodium pyrophosphate, tripotassium phosphate, phosphate-substitute salts, potassium silicate, sodium metasilicate, derivatives thereof and mixtures thereof.

15 . The method of claim 12 , the at least one fragrance being selected from natural material fragrances and synthetic aromatic agents.

16 . The method for cleaning a cooking chamber of an oven according to claim 12 , the at least one anti-caking agent being selected from tricalcium phosphate, powdered cellulose, magnesium stearate, sodium bicarbonate, sodium ferrocyanide, potassium ferrocyanide, sodium silicate, silicon dioxide, calcium silicate, magnesium trisilicate, talcum powder, sodium aluminosilicate, calcium aluminosilicate, bentonite, stearic acid, polydimethylsiloxane, derivatives thereof and mixtures thereof.

17 . The method of claim 14 , the at least one acid being citric acid and the at least one base being trisodium phosphate.

18 . The method of claim 17 , said cleanser comprising 37.5 weight percent citric acid, 37.5 weight percent sodium carbonate, and 25 weight percent trisodium phosphate.

19 . The method of claim 17 , said cleanser composition being applied to said soiled area in solid powder form.

20 . The method of claim 19 , said chamber being incubated at 150 to 200° F. for a time period of 30 to 180 minutes, said chamber being thereafter opened so that residual, loosened soils can be removed.

21 . The method of claim 12 , the steam-generating device being an onboard steam-generation unit or one or more heating elements for the chamber.

22 . (canceled)

23 . The method of claim 12 , said cleanser composition comprising 50 weight percent citric acid and 50 weight percent sodium carbonate.
