One or more polyalkylene glycols are used to improve the moisture stability of cleaning tablets and are present in cleaning tablets excluding tablets which contain (i) surfactant and builder particles coated with a polyethylene glycol having a molecular of 1,500 or which have been produced (ii) using 5 to 20% by weight of an amorphous overdried silicate, (iii) using 1 to 15% by weight of water or aqueous solutions or (iv) by compacting a particulate detergent composition with a binder distributed therein at a temperature of at least 28.degree.C, but below the melting poin t of the binder of 35 to 90.degree.C. In a process for producing a cleaning tablet, a particulate cleaning composition with one or more polyalkylene glycols distributed therein is compacted at a temperature below 28.degree.C. One or more cleaning tablets containing polyalkylene glycol may be combined with a pack accommodating the cleaning tablet(s), the pack having a water vapor transmission rate of 0.1 g/m2/day to less than 20 g/m2/day where it is stored at 23.degree.C/85% relative equilibrium humidity. The cleaning tablet s are used for cleaning lavatories, descaling, cleaning hard surfaces, manual dishwashing, machine dishwashing, bleaching, stain removal, washing and/or water softening.
