An aerator, that includes jet-defining slots and jet-fragmenting surface therein formed of or in molded plastic parts, is provided with a self-cleaning character that is achieved by providing a washer-shaped body that effects, upon initial flow of water into the aerator, a directed liquid flow at an increased velocity to effect a scrubbing action of the jet-defining slots to dislodge debris therefrom, and a plug member providing an open flow passageway through which the dislodged debris is then discharged, after which the flow passageway is automatically closed by a valve member and normal steady state aeration conditions then prevail in the aerator.
