There is no universal time that suits every mouthwash. The purpose of the product and the structure of your whole hygiene routine matter more.
In the morning
Mouthwash can be a convenient addition to a morning routine, but it should not replace brushing. If you use it immediately after toothpaste, check the recommendations about order.
In the evening
Evening hygiene should primarily include thorough cleaning of the teeth and the spaces between them. Mouthwash can be an additional step when there is a reason to use it.
Or at another time?
Some people use mouthwash during the day, separately from brushing. For products with a specific purpose, follow the label or a professional recommendation.
