How To Make This Natural Disinfectant – Step by Step

  1. In a 16 oz spray bottle, add peels of 2-3 lemons.
  2. Fill jar with with 1.5 cups of vodka (120 proof or higher). 
  3. Ideally, let lemon peels sit it the vodka for 1-2 weeks to get the lemon oil from the peels. If you don’t have the time, you can start using right away.
  4. Shake well and put the spray nozzle on.
  5. To use, spray on surfaces and let sit for a minute to disinfect. Then wipe up with a paper towel.

Note: You can use 70% isopropyl alcohol instead of the vodka. Just be aware of the surfaces you use them on (read more about the top 4 disinfectants below). You can use isopropyl alcohol with a higher alcohol content like 91% and juts add a bit of water to dilute it to 70% if you like. More on that below.

CDC Recommendation

The CDC recommends at least 70% alcohol to disinfect surfaces. The alcohol can be either ethanol (like the alcohol you drink) or isopropyl alcohol (like rubbing alcohol).

Now you’ll notice that with drinking alcohol, the alcohol content is noted on the bottles as “proof”. Divide the proof by half to figure out the percentage of alcohol in the bottle. So you’ll want to get drinking alcohol of at least 140 proof for 70% alcohol content. Make sense? Vodka can range from 80 proof to 191 proof. Everclear comes in 120, 151, 189, and 190 proof – ranging from 60-95% alcohol content.

Keep in mind that you can dilute with water to get at least 70% alcohol content. So if you have Everclear at 190 proof (which 95% alcohol), you can use 3 parts of Everclear with 1 part of water content to make a CDC-recommended disinfectant at 70% or more.

If you prefer to use isopropyl alcohol, just be mindful of the ratio. You can do 4 parts of 91% isopropyl alcohol and 1 part water, you would have a homemade disinfectant spray with 72% alcohol (91 x 4/5).

Top 4 Natural Disinfectants

There are a handful of products you can use to naturally disinfect and sanitize your home. You probably already have them in your home. They are all effective in killing germs and sanitizing surfaces and toys. Again, remember if you are following CDC recommendation stick with isopropyl (rubbing) alcohol or ethanol (drinking alcohol like vodka) at 70% or higher alcohol content.
