There are actually quite a few unexpected alternative uses for Listerine. I can use it as underarm deodorant, toenail fungus remover, and flea repellent for my dog. I never knew how helpful this mouthwash could really be.

Why Listerine? Although people generally associate Listerine with oral hygiene, it was actually intended for much more by its inventors. The Krazy Coupon Lady writes: “Did you know Listerine, which was formulated in 1879, was originally developed as a surgical antiseptic and, historically, has been used for all sorts of things? It actually wasn’t marketed for bad breath until the 1970s!” Moreover, this popular product packs a number of health beneficial ingredients including thyme, eucalyptus, and alcohol, which only explains why Listerine can be used in so many different ways aside from its regular use as mouthwash.


Listerine works great as an under arm deodorant. It acts as an astringent and antibacterial agent to reduce sweating and body odor. Fill Listerine mouthwash in a spray bottle and spray in your underarms to get rid of body odor. This is an easy way and just like using a deodorant. Another way of applying listerine is by using cotton ball or towel. Take a cotton ball or towel and soak it in listerine mouthwash and dab into your armpit.

2. Pour It Down The Toilet

It might seem like you are throwing money down the toilet, but Listerine can actually clean and deodorize your bowl.

All you have to do is pour a little in and use your toilet brush to give things a light scrub.


To use Listerine as a dandruff treatment, wet your hair thoroughly with the mouthwash and wrap your hair in a towel. Leave it for 10-15 minutes and then shampoo your hair as normal. Repeat this treatment for multiple times. The anti-fungal ingredients in Listerine will eliminate the dandruff completely.

4. Rub It On Your Dog

Listerine is a great and much safer alternative to expensive flea sprays and products for pets. To avoid the harsh chemicals in commercial flea repellents, many pet owners choose Listerine instead.

According to the Krazy Coupon Lady, try “mixing it with shampoo in a bath or diluting it with water and using it as a spray.”


Mouthwash contains a phenol-based antiseptic that will eliminate the bacteria that causes acne and pimples. Take the cotton ball and pour the Listerine on them and gently dab it on the pimple or acne affected area. The ingredients found in Listerine(eucalyptus, alcohol, and thyme) dries out the pimple and fades it.
