Homemade Disinfectant Spray Recipe | Wellness Mama

List box[Hide][Show]

I’m not big on cleaning everything up all the time, but some situations demand big guns. This spray is similar to my home-made germicides, but has a longer shelf life. It combines easy, fast, and powerful essential oils with proven disinfectants such as hydrogen peroxide or alcohol.

I made this recipe based on careful research from CDC, EPA, Stanford University, and other sources, but of course I can’t make a claim about its effect on some viruses or bacteria. This is just a formula I personally find easy to use around my home when needed. Like everything else, I encourage you to do your research and make sure that every product you use meets your own needs and standards.

Why Use Domestic Disinfectant Spray?

If you have read my other posts, you will know that I do not use antibacterial cleansers unless I absolutely do (which is not often). I buy some pre-made natural soaps and soaps, but I also enjoy keeping things simple and adding some cleaning supplies to my pantry or some neat closet cleaning supplies.

Homemade DIY cleaning recipes also help to avoid harsh chemicals because you know what’s going on in the formula. According to the American Lung Association, many chemically-equipped pesticides are linked to asthma, respiratory problems, headaches, and more. Plus some people can’t afford a cleaner with fragrances and other ingredients, or just want a natural alternative.

Since I don’t use disinfectants often, I have come up with these germicidal sprayings with ingredients and essential oils that I already had. It saves the trip to the store or another bottle in my cleaning closet.

Does it really work?

One thousand and one cleaning product recipes float on the Internet. So how do we know that a housekeeper actually does the job and we’re not just getting the scent from peppermint, the countertops covered with salmonella?

Cleaners are tested at the store to make sure they do what they say and are effective. Not really so with the home formula. However, we know a lot about natural herbicides by research published. Some natural ingredients are also on CDC-approved lists, with specific instructions on how much and how to use them.

Please, as always, do your research (I have given the link below) and get your doctor’s advice for the best procedure for your family.

Essential oils to fight germs

Essential oils are amazing little things that can pack powerful punch. One of the reasons why it is important to use them safely! It’s not enough to say that an essential oil is anti-bacterial or antiviral, and leave it there.

Some essential oils are effective against some pathogens, but not others. For example, in the 2020 article Biomolecules Clove essential oils report that Salmonella and E. coli work well against bacteria. However, lemon does not affect the bacteria due to pneumonia.

How Natural Germs Work

Viruses work differently than bacteria because they hijack healthy cells and replicate them. Some viruses also have a coating, called a viral envelope. If we do not use the correct antiviral, it cannot break the outside coating and disable the virus.

Here are some germicidal essential oils and how they work:

  • Oregano essential oils an – Antiviral, anti-fungal, anti-microbial. According to this research, viral envelope is also disrupted.
  • Clove essential oil – Interrupts anti-viral, anti-fungal, anti-bacterial and viral envelopes.
  • Thyme essential oils (timol chemotype) – Koronova kills the virus and is currently on the EPA’s approved list of pesticides for Timus, a product containing Timol.
  • Tea Tree Essential Oil – Antiviral anti-bacterial against flu viruses, including H1N1, including MRSA and other pathogens.
  • Orange essential oil – Broad-spectrum antiviral, anti-bacterial, anti-fungal
  • Red mandarin essential oil – Anti-bacterial and anti-fungal
  • Lemon essential oil – Anti-bacterial and anti-fungal

Keep it happy

Lemon oils like oranges, lime, lemons, bergamot, and grapefruit can enhance the mood. Killing harmful pathogens when we reduce stress and anxiety? Score

What are the best natural bacterial substances?

Natural germs are there. Here are some options that I have personally researched and used:


It is a popular disinfectant used for cleaning hands and hard surfaces. Many home-made products do not have enough alcohol to work well. According to the CDC, 60-90 ہے of alcohol is needed to make germs that work. (Reason for refreshing my cleanser.)

If we start with 60% alcohol and then lower it with water … we just killed the cleaner’s efficacy.

What about vodka?

The average vodka is 80 proof, or 40 percent alcohol. Even if we use it straight away that’s less than 60% recommended. If you choose vodka it needs to be at least 120 proof.

Isopropyl alcohol (rubbing alcohol)

Alcohol is available at pharmaceuticals and most grocery stores. It is cheaper than vodka and contains 70-90% alcohol so it fits on a domestic pesticide spray bill.

Note: Sensitive nose may be disturbed by alcohol-based spray smoke. If this is you, opt for hydrogen peroxide instead.

hydrogen peroxide

This impatient cleaner is hidden in bathroom cabinets nationwide. Unlike alcohol, we only need a small amount of hydrogen peroxide for sterilization. Commercial preparations use about 1% hydrogen peroxide, compared to 60-90% alcohol.

Peroxide attacks pathogens and is one of the few natural pesticides approved by the EPA. This cleaner also works against rhino viruses, flu, and viruses that cause colds. A 1977 article about “inactivation of viruses by hydrogen peroxide” reports that it disables the virus and prevents them in its tracks.

Although there is dirt and dust in this place, according to this article, hydrogen peroxide cannot properly disinfect.

If it (hydrogen peroxide) comes in contact with other components such as organic soil and soil that are not cleaned before germicidal spraying, the effectiveness will be reduced. When using hydrogen peroxide disinfectants, the application of complete cleansing before the application of sterilization will require a high priority.

Yes, cleaning the surface twice (once for dirt and the other for microbes) is annoying, but this way it works clean. Some germs take up to 30 minutes to work, but peroxide can remove germs in just one minute.


Another EPA-approved natural bacterium is Thymol. Thyme is found in high amounts in essential oils, this compound kills both viruses and bacteria. Approved commercial cleaners use 0-5% of the volume of the tumor. This does not mean that we can only use .05% thyme oil, since the content of the Timol is different.

Some thyme oil brands contain at least 26% thymol, while others contain 50% or more. That’s a huge difference when we’re looking for only .05%! Plant Therapy is one of my favorite essential oil brands and they release GCMS test reports for all their oils. This makes it easy to know how much oil is in their essential oils.

According to the EPA, wait 10 minutes before cleaning the surface-based cleaners.

Important note on essential oil selection:

To make this cleaner I have given several options so that you can use whatever you have on hand. Choose a base (hydrogen peroxide or alcohol), and select the recommended essential oils.

Note: On average, plant therapy contains approximately 40% of thyme oil. That means we need to use .55 ml or 16 ounces of 12 kg drops of cleansing solution in it to hit .05% concentration. It is better to get thymium thymol chemotype, but thymol can also work. Since the saliva in the linoleum type is very low, you will need to increase the amount used in the recipe three times.

Prescription of domestic disinfectant spray

A tough but natural sanitizing spray cleaner when I don’t have handmade pesticides


Select one of the following required options.

For an alcohol-based recipe:

  • 16 Oz 120 Proof Vodka Or rubbing alcohol

For hydrogen peroxide based prescription:


  • In a 16 ounce glass spray bottle, add the required essential oils.
  • Add alcohol or hydrogen peroxide and distilled water. Bacteria grow faster than regular tap water.

  • Close the end and shake lightly to mix.


How to use: Shake well and spray on sterile surfaces for disinfection. Make sure there is no dirt, dust or debris on the surface before use. Wait 1-10 minutes before wiping. Use door knobs, taps, light switches and other frequently used surfaces.
