Always rinse and dry your Coravin Aerator after each use.
Over time, sediment or cork particles can build up inside the Aerator leading to performance issues. Follow these steps to clean any version of the Aerator: (1) Unscrew the Aerator head from the rubber housing. (2) Remove the screen from the rubber housing. (3) Soak all three Aerator parts in warm water for a few minutes. Pay attention to the screen to make sure there are no cork particles in the holes.
(4) After soaking the Aerator parts, rinse them under running water. You may see cork particles rinse out.
(5) Once the parts are dry, put the Aerator back together by placing the screen into the rubber housing.
(6) Then screw the Aerator head tightly onto the rubber housing.
