A method of washing dishware in an automatic dishwashing appliance, wherein the method comprises the steps of:
- (a) placing a water-soluble automatic dishwashing detergent pouch comprising an automatic dishwashing detergent composition that is enclosed by a water-soluble film inside the dispenser drawer of an automatic dishwashing appliance and closing the dispenser drawer;
- (b) placing automatic dishwashing detergent particles into the cleaning chamber of an automatic dishwashing appliance, wherein each particle has an individual mass of from 1.0 mg to 1.0 g and a maximum dimension of from 2.0 mm to 10 mm, and wherein each particle comprises from 25% to 99% by weight of a water-soluble carrier, and a detergent ingredient;
- (c) introducing first water into the cleaning chamber and performing a pre-wash of the dishware contained therein, wherein during step (c) at least some of the automatic dishwashing detergent particles dissolve such that at least some of the detergent ingredient comprised within the particles is released into the first water;
- (d) optionally, removing at least some of the water from cleaning chamber;
- (e) introducing second water into the cleaning chamber and performing a main wash of the dishware contained therein, wherein during step (e) the closed dispenser drawer is opened and at least part of the water-soluble film dissolves such that at least some of the detergent composition enclosed therein is released into the cleaning chamber;
- and
