What do i do after using mouthwash?

See details: Rinse your mouth with water and don't do anything.

Spit it out: It is not adviseable to swallow mouthwash. Since mouthwash is used after flossing and brushing, you can go about your day if done upon waking or just go to bed if in at bedtime.

Typically : One spits it out. I don't know if you meant something else by the question. If so please resubmit with more details. Hope this helps.
