The invention concerns a bleach product for use in the washing machine as an adjunct to a normal detergent powder or liquid. The product consists essentially of a particulate bleach compositon and which is substantially free of other detergent components and which is contained within a non-coated bag of sheet material having a porosity to air of 5,000 to 10,000 liters/m.sup.2 /s. The bleach composition comprises sodium perborate with an activator such as tetraacetyl ethylenediamine or sodium octanoyloxybenzene sulphonate. Preferably at least 25 mole percent of the perborate is in monohydrate form in order to provide reduced malodor development on short storage.
