A detergent composition includes about 2 wt. % to about 50 wt. % of a first metal silicate having the formula: <?in-line-formulae description="In-line Formulae" end="lead"?>M<SUB>x</SUB>O<SUB>y</SUB>.mSiO<SUB>2</SUB>.nH<SUB>2</SUB>O <?in-line-formulae description="In-line Formulae" end="tail"?> wherein 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<SUB>2 </SUB>to M<SUB>x</SUB>O<SUB>y </SUB>is at least about 1.6, and about 0.5 wt. % to about 10 wt. % of a second metal silicate having the formula: <?in-line-formulae description="In-line Formulae" end="lead"?>M<SUB>x</SUB>O<SUB>y</SUB>.mSiO<SUB>2</SUB>.nH<SUB>2</SUB>O <?in-line-formulae description="In-line Formulae" end="tail"?> wherein 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<SUB>2 </SUB>to M<SUB>x</SUB>O<SUB>y </SUB>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.
