Do you know how to make hand sanitizer? DIYing it at home could help you fight germs amid the Covid-19 pandemic. Now that the supply chain is catching up with demand, finding where to buy hand sanitizer has become easier, but you may still have trouble finding Purell in your area. Here's how to make your own hand sanitizer at home using the materials at your disposal.

Our checklist of coronavirus tips warns that hand sanitizer is not the ultimate defense against contracting the virus. The best way to stay healthy is to practice basic hygiene habits, such as washing hands regularly and keeping hands away from the face. Also, for the health of the community, rules for social distancing in the community need to be followed.

The important thing to know about how to make hand sanitizer at home is the percentage; according to the CDC, you must make the sanitizer with 60% alcohol to be an adequate option to prevent the spread of disease.

Also, if hands are visibly dirty or greasy, hand sanitizers may not be as effective. However, if you can't find it at your local pharmacy, or if you think it's better than buying it on Amazon for a ridiculous price, it's worth making some to keep on hand throughout the day.

Here are some tips on how to make your own hand sanitizer at home and how to use it properly.

A biomedical doctor has broken down what you will need to make your own hand sanitizer at home. Some of these items may already be familiar to you, and if not, they may be easier to find than Purell. I have also included links to where you can find these materials online.

Step 1: Mix the rubbing alcohol, aloe vera, and optional essential oils in a bowl with a spoon. Be careful not to let the alcohol come in contact with your skin.

Step 2: Pour the mixture into an empty bottle. Replace the pump cap and your hand sanitizer is ready to use.

While it is easy to make your own hand sanitizer, it is important to note that using large amounts of rubbing alcohol can damage the skin. Make sure to use a 2:1 ratio so that the alcohol content is around 60%. One can also use gloves when mixing and follow up the disinfectant with a hand moisturizer.

It also goes without saying that hand sanitizers alone will not protect against illness. Wash your hands when soap and water are available and limit the amount you touch your face. For the latest information and facts about the disease and its spread, see our sister site LiveScience's coverage.
