The invention relates to highly alkaline, storage-stable oven and grill cleaners in the form of sprayable, viscous, aqueous solutions based on alkalis, surfactants and water-miscible organic solvents, the very specific amounts of an alkali, an alkylbenzenesulfonate, a nonionic surfactant, a solvent containing hydroxyl groups and optionally contain a finely divided, mineral solid and water. The process for the preparation of the cleaning agents mentioned consists in first dissolving free alkylbenzenesulfonic acid in water, then neutralizing with the alkali, stirring being carried out in order to avoid lump formation. Then you add the excess proportion of alkali and the remaining ingredients of the recipe with stirring. If a mineral solid is added in the particular embodiment, it is first dispersed in water and then proceed as described above. |
