This super easy and cheap DIY disinfectant spray (like Lysol spray) is great at killing germs and uses way simpler ingredients than store-bought.
Pour water and hydrogen peroxide in a 16-ounce spray bottle. Drop in desired essential oil blend, optional. Fill bottle with ethyl alcohol, about 12 ounces, and shake well to combine. Spray and wipe down on high-touch areas or anywhere you'd like to disinfect.
You must absolutely make sure your mixture is 60%+ alcohol, or it will not be effective.
My mathematician friend wrote an equation for calculating the desired final alcohol percentage,so check out his super helpful walk-through of this if you need help.
For other types of alcohol, use this online calculator to help you know how much water to use. This calculator produces an 75% alcohol, and we do not use as much hydrogen peroxide in our recipe as the calculator. However, it is generally very helpful in knowing about how much water you can to use.
Types of essential oils to use:
Tea tree, eucalyptus, and thyme were actually studied for their antiviral properties, so we include these in most of our disinfectant blends.

Continue to use germ-fighting best practices as recommended by the CDC, such as regular, proper hand-washing, coughing or sneezing into your elbow, etc. Visit their site for more information.
