Listerine as Sanitizer

Bottle of hand sanitizer with Listerine.Editor's Note: Regular amber Listerine contains 26.9% alcohol, which isn't strong enough for use as a sanitizer. The CDC recommends at least 60% alcohol to be effective.


I love the amber colored mouthwash, whether name brand or not. It is useful for so many things. When my hand sanitizer small bottles are almost empty, I shake them up with the antiseptic mouthwash in them. This formula cleans hands as well as the hand sanitizer if not better.

It you wash and fill the hand sanitizer bottle with just Listerine, you can squirt some on your toothbrush and clean it before you brush your teeth. It does quite a job by itself, for brushing teeth.

It is really nice to have a bottle around in the kitchen as well to squirt a little in the dishwater or on a utensil to clean with, and then rinse. There are all sorts of ways to use this kind of mouthwash and I always have it on hand.

The original Listerine is only 26% alcohol, so is too weak to be an effective sanitizer. For virus prevention, any homemade sanitizer should be at least 60% alcohol.


It would be better to a high strength isopropyl alcohol instead.

Its not just the alcohol kill the germ, .050-.080 % of Eucalyptol is equivalent as alcohol. Also benzoic acid.

70-99.9% of alcohol is damaging to your skin and I prefer Eucalyptol and benzoic acid than alcohol if applied to human body.

Listerine contains thymol.the u.s. e.p.a. studied thymol and issued a public statement saying that thymol kills germs and viruses as well as bleach.bleach kills caronavirus. The u.s.e.p.a. advises the c.d.c. on disinfectants.

Listerine has a page about COVID19 on their website. They don't recommend using it for anything but mouth care as it has not been tested. There is some potential for thymol and other essential oils to be effective but, again, it has not been tested. I wouldn't count on this protecting you from viruses.


The Listerine website states:

"LISTERINE® mouthwash has not been tested against any strains of coronavirus.

Only some LISTERINE® mouthwash formulations contain alcohol, and if present is only around 20% alcohol. LISTERINE® mouthwash is not intended to be used, nor would it be beneficial as a hand sanitizer or surface disinfectant."

Here is the direct link:

My general use sanitizer consist of 1 cup Listerine or any antiseptic mouth rinse to 2 cups of water and 3/4 Tsp. of bleach place into spray bottle shake well. The mouth wash also gives it a nice aroma. Spray on counter tops; kitchen , Bathroom, door nobs, in your car , after using the toilet, wash your hand and you may spray with the solution, etc, etc.


I did not know what to call it, so I call it El-sanitizer

Of course it's good, really good. Don't spread the news too fast, for shelves will emptied rapidly. I mix it this way: 150ml of Listerine, 10ml of peroxide ( h2o2 ) at 3% and 5ml of glycerine. And it smell good too, and softer for the skin than alcool.
