As a Krazy Coupon Lady I usually have a pretty good stockpile of Listerine on hand, but I still always grab more when I see a deal come up. That’s not just because I want to banish bad breath, but because it has such a wide variety of uses! In fact, 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! If you’ve got a stash of Listerine sitting in your bathroom closet, check out some of the cool, unconventional ways that you can use it — and maybe save yourself a few bucks!

1. Get rid of blemishes

We all get blemishes from time to time, and most people want nothing more than to get rid of them quickly. But what do you do when you don’t have any acne products? You guessed it – Listerine! The ingredients found in Listerine, including eucalyptus, alcohol and thyme can kill bacteria that cause acne. Simply dab Listerine on the affected area using a clean cotton ball, and skip the pricey products. Just be sure not to use too much, and be cautious if you have sensitive skin.

2. Clean your toothbrush

Listerine is great for killing germs, which is why we use it, after all. So why not use it to clean your toothbrush after each brushing? I’ve seen toothbrush sanitizers priced at upwards of $40, and although these claim to eliminate 99.9 percent of germs, immersing your brush in Listerine for 20 minutes has been proven to be just as effective.

3. Get rid of dandruff

Dandruff, which is actually caused by a fungus called Pityrosporum, can not only be embarrassing, but it can be extremely uncomfortable and itchy. Listerine, along with other antiseptic mouthwashes, is actually made with anti-fungal ingredients, making it a great remedy for dandruff. To use Listerine as a dandruff treatment, wet your hair thoroughly with the mouthwash and wrap your hair in a towel. Let it sit for 15 minutes and then shampoo as normal.You may need to do multiple treatments before the Listerine kills off all of the fungus and eliminates the dandruff completely.

4. Banish stinky feet

Many of us often have foot odor, even if we don’t want to admit it! Luckily, the alcohol and extracts found in Listerine make it an extremely effective remedy. To keep foot odor at bay, soak a cotton ball in Listerine and rub it all over your feet. You can rub a small amount along the inside of your shoes, as well. Using Listerine has more than one perk for feet – it has been shown to help alleviate athletes foot, as well.

5. Kill germs and odors in your garbage disposal

Speaking of stinky things, have you ever been cooking in your kitchen and noticed a foul smell emanating from your sink? I had a terribly stinky sink and tried everything to get rid of the smell, including lemon peels, oranges and even baking soda. Nothing worked – until I tried Listerine! To eliminate sink odors, simply pour half a cup of mouthwash down the disposal.

6. Get rid of fleas

Despite the fact that my dogs are inside most of the time, they somehow end up with fleas every so often. Usually I go into panic mode and run out and buy every item on the shelf that claims to kill fleas, but no longer will I spend a small fortune on these products — Listerine will do the job! You can use the Listerine in a couple of different ways, including mixing it with shampoo in a bath or diluting it with water and using it as a spray.

7. Use as a deodorant

Okay, I know what you’re thinking – a KCL run out of deodorant?! Perhaps it’s not likely, but on that off chance that you actually do find yourself without a stick of deodorant, now you can have a backup. Simply dab a bit of the mouthwash on a cotton ball or towel, wipe it on your underarms and you’re good to go!

8. Kill mold and mildew

Because Listerine kills odors and disinfects, it is a great cleaner – particularly on mold and mildew. Grab one of those old toothbrushes, soak it in Listerine and scrub away that shower gunk! You can also use it to clean toilets, sinks, floors and even as a general cleaner. If you’re using Listerine on shower mold or mildew, you can use it full strength, but if you want to use it to clean other things around the house, fill a spray bottle with half Listerine and half water. Not only will you have a clean house, but it will smell minty fresh!
