Okay, so when I talk of "Listerine", I do also mean the off brand as this is what I mainly use. Listerine is a wonderful way to have a fresh mouth by killing germs but that's not all, my friends!
It's good for cleaning as well. Yesterday I mopped my floor with it and even after rinsing out the mop, it still smelled Listerine fresh. Do you want a fresh smelling toilet? Use Listerine! Seriously. Try it!
