How to Make Alcohol Disinfectant Spray

With the recent outbreak of the COVID-19 virus, it has become more important than ever to keep our surroundings clean and disinfected. One effective way to do this is by using alcohol-based disinfectant sprays. While these sprays may be in high demand and short supply, you can easily make your own at home with just a few simple ingredients. In this article, we will guide you through the process of making alcohol disinfectant spray.


– Isopropyl alcohol (99% concentration)
– Distilled water
– Essential oil (optional)


1. Start by pouring 2/3 cup of isopropyl alcohol into a clean spray bottle. Make sure the concentration of alcohol is 99%, as lesser concentrations may not be as effective.

2. Next, add 1/3 cup of distilled water to the spray bottle. Distilled water is preferred to ensure purity and prevent any unwanted impurities or contaminants.

3. If desired, add a few drops of essential oil. This is purely for fragrance purposes and is optional.

1. Can I use rubbing alcohol instead of isopropyl alcohol?
Rubbing alcohol typically contains isopropyl alcohol, so it can be used as a substitute. However, be sure to check the concentration, as it should be 99%.

2. How often should I use the alcohol disinfectant spray?
It is recommended to use the spray daily on high-touch surfaces or whenever necessary.

3. Can I use vodka or other alcoholic beverages?
While vodka or other alcoholic beverages may contain alcohol, they are not suitable for making disinfectant spray due to their low alcohol concentration.

4. Is it safe to use the spray on electronics?
It is generally safe to use the spray on electronics, but avoid spraying directly onto the device. Instead, spray onto a cloth and then wipe the surface.
