Use it as a deodorant in a pinch
Have you ever run out of deodorant just before a date in the dead of summer? Do not fret! If you are ever in an emergency, there is a helpful alternative: use some mouthwash! It can help kill the germs that give body odor that pungent smell. Although it may not wholly replace deodorant, you will no longer have to worry about smelling.
This is a helpful hack if you ever wished your body to have the same minty fresh scent as your mouth. Instead of gargling it like usual, try rubbing some breath freshener onto the more moisture-prone parts of your body. This method will not keep you from sweating, but the antibacterial action within most oral hygiene rinses will keep you from getting stinky.
