Introduction: DIY Hand Sanitizer for COVID-19
I am going to show you how to make your own hand sanitizer with regular household items around the house to help you combat the coronavirus. Obviously, this should only be used as a last resort. I seriously recommend using commercial hand sanitizer. But in the case that isn’t an option, turn to this.
Supplies
91% Isopropyl Alcohol (Don’t use 70%)
Aloe Vera gel
Empty bottle
Mixing Bowl
Funnel
Spoon
Measuring Spoon
Step 1: Research Findings
It turns out you need your hand sanitizer to have about 60% alcohol to be effective against most viruses like Covid-19. We are using a 91% alcohol in our hand sanitizer, but we need to mix it with something so it doesn’t evaporate too quickly and isn’t so harsh on the hands. It turns out a 3 to 1 mixture of the 91% alcohol and Aloe Vera makes your hand sanitizer have about a total 60% alcohol content.
Step 2: Mixing the Ingredients
Start by measuring out the Aloe Vera. Make however much you want, but remember you need to have 3 times the alcohol to Aloe Vera in your end product. I just made a small batch to test it out. I took a 1 teaspoon measuring spoon of Aloe Vera and put it in the mixing bowl.
Then I added 3 teaspoons of alcohol to it and started stirring with the spoon. It took a few minutes to get it to homogenize.
Step 3: Pouring Into Bottle
Pretty simple. Use the funnel to help get your hand sanitizer into the bottle.
Step 4: Using It!
It felt pretty good using it. The aloe made it not irritating to my hands. It did smell pretty strong of alcohol though.
I hope this is helpful to anyone. Thanks for viewing my instructable and please vote for it in the 2020 Spring Cleaning Contest!

A 3-to-1 ratio of alcohol to Aloe will give you an alcohol concentration of ~68%=(3*91%)/4. A 2-to-1 mixture will give you an alcohol concentration just above 60%=(2*91%)3.

Interesting instructable but according to WHO, you need 75-80% concetration of alcohol.

Well, the CDC recommends a hand sanitizer have at least 62% to 70% to kill Covid-19. Which is basically every store bought hand sanitizer. I even found out Aloe Vera gel has some alcohol in it. So I would say my formula is close to 65%. While your page is a good recommendation, it doesn't directly address killing Covid-19.
