ABSTRACT In non-aqueous liquid cleaning products compositions comprising dispersed particles of aluminosilicate builder, components sensitive to decomposition catalysed by aluminosilicate, such as bleach precursor, can be protected if the aluminosilicate particles are deactivated by pre-treatment with an ammonium or substituted ammonium compound, followed by a heating step to reduce the water level of the aluminosilicate.
