Mouthwash is usually kept in the bathroom for one job: freshening breath and supporting oral care. But because many mouthwashes contain alcohol and antibacterial ingredients, they can be useful in other small, practical ways around the house as well.

While it’s not a replacement for proper cleaners or medical products, mouthwash can work as a backup solution for certain tasks when used carefully. Here are 10 quirky yet useful ways people repurpose mouthwash beyond just brushing their teeth.

1. Clean Household Surfaces

If you’re out of all-purpose cleaner, mouthwash can help in a pinch. Apply a small amount to a cloth and wipe down countertops, glass, or bathroom surfaces. Stick to clear mouthwash to avoid residue.

2. Deter Fungus Gnats on Plants

Diluted mouthwash can help discourage fungus gnats and mildew around houseplants. Mix equal parts mouthwash and water, and lightly spray the soil surface. Test first and use sparingly.

3. Help With Mild Foot Fungus

For mild cases of athlete’s foot, some people use alcohol-based mouthwash as a temporary treatment. Apply with a cotton ball to clean, dry skin. Discontinue if irritation occurs.

4. Make Cut Flowers Last Longer

Adding a small amount of mouthwash to the water in the flower vase can help slow bacterial growth. This can extend the life of fresh flowers by keeping the water cleaner for longer.

5. Freshen a Humidifier

Humidifiers can develop odors if not cleaned often. Adding a small amount of mouthwash to the water may help reduce bacteria and odors. Always check your humidifier’s manufacturer guidelines before trying this.

6. Deodorize a Garbage Disposal

Unpleasant smells from the disposal can sometimes be reduced by pouring a small amount of mouthwash down the drain and running hot water briefly.

7. Freshen a Garbage Can

For lingering odors in trash bins, soak a paper towel with mouthwash and place it at the bottom of the can. This helps absorb smells between cleanings.

8. Reduce Odors in Laundry

Clear mouthwash can help neutralize odors in smelly clothes or washing machines. Add a small amount to a load or run an empty cycle to help reduce musty smells.

9. Clean Tile Floors

Diluted mouthwash can be used on tile floors for light cleaning. Mix with water and mop as usual. Avoid using on delicate or natural stone surfaces.

10. Disinfect Minor Cuts

Alcohol-based mouthwash can be used to clean minor cuts or scrapes when first-aid supplies aren’t available. This should only be done for small wounds and may sting on contact.
