A multi-compartment water soluble dishwashing pouch having an internal volume, a first outer surface and a second outer surface, the pouch comprising:
- a first pouch material forming said first outer surface, said first pouch material having edges;
- a second pouch material forming said second outer surface, said second pouch material having edges;
- a barrier positioned within said pouch between said first pouch material and said second pouch material, said first pouch material, said second pouch material and said barrier being sealed adjacent said edges of said first pouch material and said second pouch material so as to divide said internal volume into
- a first compartment comprising said first outer surface and said barrier, and
- a second compartment comprising said second outer surface and said barrier;
- a particulate automatic dishwashing product positioned in said first compartment;
- and
- a dishwashing auxiliary comprising an anhydrous liquid, gel or paste positioned in said second compartment.
A multi-compartment water soluble dishwashing pouch having an internal volume, a first outer surface and a second outer surface, the pouch comprising:
