Kill the germs that cause bad breath! Combine cheap vodka with a few drops of cinnamon, spearmint, or tea tree oil and let sit for two weeks. You've got your own high-octane mouthwash. Just make sure to spit after you rinse.
And next time you've had too much vodka, you can use the vodka mouthwash to freshen your breath! No one will be the wiser.
