To obtain a compact cleaner for industrial dishwashers highly alkaline, alkali hydroxide based detergents are prepared. The detergents have the combined advantages of powders and liquids on the one hand, and of pellets and molten solidified blocks on the other hand and also present controlled variable stability during production and storage. This is achieved when, in order to obtain increased viscosity, aqueous alkali metal hydroxide lye is mixed with HOCH2CH(R1)OR2 and/or [HOCH2CH(R8)3-x]NHx, wherein: R1 is a hydrogen atom, a C1-4 alkyl group, a CH2CH(R3)OR4 group or a CH2CH(R5) OCH2CH(R6)OR7, R3, R5 and R6 represent hydrogen atoms or methyl groups R4 and R7 represent hydrogen atoms or C1-4 alkyl groups R8 is a hydrogen atom or a methyl group x is 0, 1 or 2 To this composition, solid alkali metal hydroxide, preferably potassium or sodium hydroxide, more preferably sodium hydroxide and/or surfactants and/or paraffin oil and/or polyhydroxy compounds, preferably glycerol, and/or builder components and/or foam inhibitors are subsequently added.
