A detergent composition includes about 2 wt. % to about 50 wt. % of a first metal silicate having the formula: n nM x O y .m SiO 2 .n H 2 O n nwherein M is at least one of an alkali metal or a transition metal, x and y are independently integers of 1 to 3, m is greater than 0.2, and n is 0 or greater, and the weight ratio of SiO 2 to M x O y is at least about 1.6, and about 0.5 wt. % to about 10 wt. % of a second metal silicate having the formula: n nM x O y .m SiO 2 .n H 2 O n nwherein M is at least one of an alkali metal or a transition metal, x and y are independently integers of 1 to 3, m is greater than 0.2, and n is 0 or greater, and the weight ratio of SiO 2 to M x O y is less than about 1.5. The detergent composition can be used to clean the interior surface of an oven. A method for cleaning polymerized food soil is provided. |
