Mouthwash is not really a dental hygiene thing.

If you need to use mouthwash to prevent bad breath even when you brush your teeth and clean your mouth properly, you need to look into what might be causing that problem in the first place. Mouthwash is like a duct-tape workaround and probably not very healthy for you either.

Btw - interdental toothbrushes. If you’re not using them already, you may want to start. Very helpful. Much better than flossing which has some problems associated with it.
