A malodour-counteracting device adapted to be used in an automatic dishwasher having at least one washing cycle and a final drying cycle, the device having the form of two connected containers, adapted to rest on a horizontal surface within the dishwasher to provide an upper container (2) and a lower container (1), the lower container having the form of an open dish and the upper container, within which is a gradually-releasable evaporable malodour counteractant (6), fitting within the lower container and providing at least one port (3) permitting the passage of malodour counteractant out of the upper container, the lower container being adapted, during the washing cycle, to contain sufficient water to submerge the port, and during the drying cycle to allow the port to be open. The device is easy and cheap to manufacture, and is effective for a prolonged period.
