Myth 6: Mouthwash is just for your mouth
Mouthwash doesn’t always have to go in your mouth to be useful. It’s a good cleansing product for mouth guards, for instance. Some people also swear by alcohol-based mouthwash for dandruff control, wound care, toilet bowl disinfectant and even underarm deodorizer. You won’t find these uses on the product label, however, so apply them at your own risk.
