Homemade Uhhhhh Mouthwash

Mouthwash is now more expensive than vodka. So buy the latter and either gargle it straight or add a bunch of mint/extract and maybe a tablespoon of salt and another of licorice, or add anything out of your spice cabinet or a bunch of random herbal tea bags, and maybe water it down a little (just a little if at all), and you've got your own, proper, mouthwash.
