But, probably, this video addressed to mini-dosers, who use the dynavap without touching air-port (open-air-port-technique).

I don’t like aftertaste of DCG or other cleaning solutions. Maybe I’m too sensitive, but I feel it, not matter how much I rinse in water.
You need ultra-sonic bath to clean dcg between discs inside of cap.
