A water-containing solid detergent having a delayed, controllable and variable hardening time after addition of all the components produced by providing a) aqueous 42 to 55% lye, in a quantity of 21 to 70% by weight, b) mixing with the aqueous lye a compound selected from the group corresponding to formula (I): <paragraph lvl="0"><in-line-formula>HOCH2CH(R1)OR2 (I) </in-line-formula> in which R1 is a hydrogen atom or a methyl group and R2, independent of R1, is a hydrogen atom, a C1-4 alkyl group, a group CH2CH(R3)OR4 or a group CH2CH(R5)OCH2-CH(R6)OR7, where R3, R5, and R6 represent hydrogen atoms or methyl groups and R4 and R7 represent hydrogen atoms or C1-4 alkyl groups, and compounds corresponding to formula II: <paragraph lvl="0"><in-line-formula>[HOCH2CH(R8)3-xNHx (II) </in-line-formula> in which R8 is a hydrogen atom or a methyl group and x is the number 0, 1 or 2, in a total quantity of 0.5 to 40% by weight, adding thereto c) a foam inhibitor, builder component, paraffin oil, or surfactants, or polyhydroxy compounds in the order given, and finally adding thereto d) 2% to 25% by weight of solid alkali metal hydroxide, all weights being based on the weight of the detergent.
