Oven surfaces that are encrusted with grease, oils, fats and carbonized food materials are less efficient as heat conductors. Heavy build-up of soils can interfere with the radiation of heat in a uniform manner, causing hot spots to develop. This can cause the oven to use more heat energy to overcome the effects of this insulation layer. Foods cook more evenly when this layer is removed. This oven and grill cleaning compound penetrates through the layers to dissolve and emulsify them. Oven racks, grills, barbeque grills, broiler pans, smokers, deep fryers and exhaust vents can be restored to a clean appearance and an optimum performance level with regular cleaning and maintenance.
