1 1/2 cups100 proof alcohol (vodka) or higherget the highest proof alcohol you can find (in some states you can buy 190 proof, which is Everclear, if not at least 100 proof) or at least 70% isopropyl rubbing alcohol. Rubbing alcohol can damage painted and varnished surfaces so it's best to spot test first.*
Pour the vodka into a 16 ounce spray bottle and then the essential oil(s). Shake the bottle to combine the vodka and oils. Finally, add the vinegar and shake the bottle again. This recipe is not safe to use on special stone surfaces, like granite or marble, due to the vinegar. Please see the notes section below for more information.
*100 proof alcohol does not equal 100% alcohol. There has been some confusion about this, as this is different in some countries. In the US (where I live), a 40% ABV (alcohol by volume) is 80 proof and one that is 45% ABV is 90 proof. And so on. A 50% ABV is 100 proof and it goes higher from there. The essential oil is added as an antibacterial ingredient. Hydrogen peroxide can also work as a disinfectant when used straight (not diluted with anything and don't mix with vinegar!). Just be careful with hydrogen peroxide as it can bleach colored fabrics. Cutting Board Note: When it comes to disinfecting cutting boards (after cutting raw meat), I disinfect the surface usingvinegar and hydrogen peroxide (do not combine these ingredients in one bottle!); the order doesn’t matter. First spray one ingredient, letting the disinfectant rest for five minutes, then wipe the surface with a cloth. Finally, repeat with the second disinfectant. Wait five minutes, then wipe the surface with the cloth. You can see the entire process in this cutting board post. Another disinfectant spray option in the kitchen is a Bandit Oil Spray.CORONA VIRUS UPDATE: With coronavirus on the rise, this post is particularly helpful from a pediatrician. She specifically addresses coronavirus. I'm not a doctor or disease specialist. Please consult your doctor and the CDC website to do your own research about the best ways to protect your family. The CDC recommends disinfectants contain 60% alcohol or higher.
