Gargrin Zero is good.

I didn't used to use mouthwash much, but lately I've been using it every morning and evening. Brushing alone leaves my mouth feeling a bit dry, so using mouthwash along with it makes it feel much fresher.

They used to come out with added coloring, but nowadays they come out completely colorless, so I think it's cleaner and better.

It's even better because it has a large capacity so I can use it for a long time.
