Even if you forget to use it regularly (we don't judge, of course), you probably have a bottle of mouthwash hanging out somewhere in your bathroom. Most of us know it and use it for its ability to freshen breath and maintain oral health. But did you know that this cheap and powerful liquid has a variety of lesser-known uses that can really simplify your life? Simplify has rounded up some of the best mouthwash household hacks you never knew you needed, so go look for that bottle of Listerine! (Or any other brand, of course.)

Mouthwash: Not just for fresh breath.

1. Disinfect and deodorize garbage disposals

Does your garbage disposal smell less than fresh? Pour half a cup of mouthwash down the drain and let it sit for a few minutes. Run the disposal and some water to clear it out. The mouthwash will not only disinfect but also leave a minty-fresh scent behind.

You can keep your food waste disposal extra fresh with just a little mouthwash at a time.

2. Soothe insect bites and rashes

Mouthwash can be an effective remedy for relieving itching and discomfort caused by insect bites and mild skin rashes. Dab a cotton ball soaked in mouthwash onto the affected area to soothe irritation and reduce inflammation.

3. Give smelly laundry an extra-fresh boost

Just gave it your all at the gym and need to do laundry pronto? No worries! If your laundry needs a little extra deodorizing, add a cup of mouthwash to your washing machine along with your regular detergent. The mouthwash will help eliminate odors and give your clothes a fresh, clean scent.

Mouthwash will really take the edge off smelly laundry if you use it with your regular detergent.

4. Mini-foot spa time

Treat yourself to a relaxing foot soak that also combats foot odor and the risk of fungus. Fill a basin with warm water and add a cup of mouthwash. Soak your feet for 15-20 minutes, then pat dry. Your feet will be refreshed, and any lingering odors will be eliminated.

5. Disinfect toothbrushes

Your toothbrush can harbor bacteria over time. To keep it clean and sanitized, soak your toothbrush in a glass of mouthwash for 15 minutes once a week. This will help kill germs and keep your toothbrush fresh.

6. Clean your toilet

Mouthwash can double as a handy toilet cleaner. Pour half a cup of mouthwash into the toilet bowl, let it sit for 10 minutes, then scrub with a toilet brush and flush. The mouthwash will help remove stains and leave your bathroom smelling fresh.

Pour some Listerine down the toilet and see how well it works!

7. Get rid of mildew in the shower

Mildew on your shower curtain is a pesky problem that mouthwash can help combat. Fill a spray bottle with equal parts mouthwash and water, and spray the solution onto the affected area. Let it sit for a few minutes, then scrub gently and rinse with water. Your shower curtain will be mildew-free and fresh-smelling.

8. Keep your flowers fresh for longer

Extend the life of your cut flowers by adding a couple of tablespoons of mouthwash to the water in your vase. The mouthwash will help prevent the growth of bacteria, keeping your flowers fresher for longer.

Adding mouthwash to your bouquet will really add to its lasting power.
