Listerine was supposed to have a wide variety of uses when it was created, and not only used as a mouthwash.
It was invented in 1879, as a surgical antiseptic used for various purposes, and it began to be marketed as a mouthwash against bad breath in the 1970s!
Here are some interesting uses of Listerine:
Clean your screens
You can spray it on a soft cloth and use it to wipe away dirt and fingertips from the screens of the TV and computer.
Get rid of fleas on the dog
Rub some Listerine on the skin of your dog to eliminate fleas, instead of the expensive products full of chemicals.
