An apparatus for rinsing plastics material containers, with a conveying device which conveys the plastics material containers along a pre-set conveying path, with a plurality of spraying devices which act upon an inner space of the plastics material containers with a gaseous medium and which are designed to be movable at least locally with the plastics material containers, with a reservoir for the gaseous medium and at least one connecting line by way of which the reservoir is connected in terms of flow to the spraying devices. The apparatus has an ionizing unit which is arranged between the reservoir and the spraying devices and which ionizes centrally the gaseous medium arriving at the spraying devices.
