Homemade disinfectant

The key ingredients that make up this natural, non-toxic homemade disinfectant are lemon juice and grapefruit essential oil. Lemon juice has many uses. Besides being used in cooking and baking, it is also a fantastic disinfectant!

Grapefruit is also a natural disinfectant. Thus, when you combine the two, you have a powerful homemade disinfectant that is simple and very cost-effective.

Toxic ingredients in popular disinfectants

Some common toxic ingredients in many disinfectants include bleach, ammonium, Phenol, formaldehyde, petroleum, Butyl cellosolve and Triclosan. These ingredients can trigger cancer, cause respiratory problems, damage to kidneys and lungs, to name a few.

In addition, using chemical disinfectants can kill all bacteria. But it is healthy to come into contact with some bacteria, otherwise, the ability of our immune system is compromised and we become more resistant to disease (source).

Natural ingredients

You will already have some of the ingredients on hand (water) and you may have lemon juice on hand as well. In addition, I would strongly suggest that you get yourself some essential oils as well as some castile soap; these are staple product ingredients that can be used in many DIY recipes.

Making your own homemade cleaning products (and personal care products) is fun, rewarding and wonderful because you can personalize the scent you want as there are many different essential oils available.

Furthermore, most essential oils offer health benefits. For example, grapefruit essential oil is an anti-fungal and an anti-depressant as well. So, in addition to cleaning your house inexpensively, with safe product ingredients, you can reap the added benefits of essential oils at the same time.

Update: I recently made this DIY disinfectant with vinegar instead of lemon juice. I love recipes with lemon juice because it smells better than vinegar. However, lemon juice is supposed to be kept in the fridge and I was afraid that, even though you cannot smell it, the lemon juice might become rancid.

Here is what I changed: I substituted the lemon juice for vinegar and added 15 drops each of lime, lemon, grapefruit and orange essential oils. This combination masked the smell of the vinegar and, to my surprise, smells amazing!

Homemade Disinfectant with Grapefruit and Lemon Juice
  • 2 cups water (distilled or boiled)*
  • 2 tbsp lemon juice
  • 1/4 cup castile soap
  • 20 drops grapefruit essential oil
  1. Pour the water into a glass or BPA free spray bottle (before the oil to prevent bubbles).
  2. Pour in the lemon juice.
  3. Add the castile soap.
  4. Add the grapefruit essential oil.
Recipe Notes

Using distilled or boiled water diminishes bacteria and other impurities in the water.

*You can use vinegar instead of lemon juice if you like.

* You could also use lemon essential oil.

* If you do not have grapefruit essential oil for this homemade disinfectant, place the rind from 1 or 2 grapefruits into 2 cups of vinegar in a mason jar and let it sit for 2 weeks. You can then use this as a substitute for the water and grapefruit essential oil. You can also omit the lemon juice, or you can leave it as it may help to minimize the smell of the vinegar.

Where I buy my ingredients

I am very frugal. My mom taught me well. I always hunt down the best products for the best price. Here is a list of what I used and where I bought it.

  1. Castile soap – local grocery store (Superstore) or Well.ca
  2. Grapefruit essential oil – Plant Therapy or Amazon

If you are not up for making your own homemade disinfectant, I recommend this kind.
