Most viruses like COVID-19 spread through human contact, and one of the most effective ways to prevent its spread is by washing your hands. But sometimes when you are out and about, you may not have access to a wash basin. That’s where alcohol based hand rubs and sanitizers come in handy.
The sudden demand for sanitizers has resulted in a shortage and in some places overpriced products. Incase you are facing a shortage of hand sanitizer too and want to make your own, here’s a basic recipe that has been certified and published by WHO
WHAT YOU NEED:
Isopropyl Alcohol (99.8%)
Hydrogen Peroxide (3%)
These are common ingredients and can be easily bought from a Chemist.
HOW TO MAKE 1 LITER:
751.5ml Isopropyl Alcohol
41.7ml Hydrogen Peroxide
Top it up in a flask with distilled water till it reaches the 1000ml mark and shake gently to mix the contents. Let it sit for 72 hours before using. WHO recommends not to add any other ingredient to it as it may compromise its antimicrobial efficacy.
HOW TO USE:
- Spray/Apply a palm-ful and rub all over your hands until dry.
Alcohol is a bit drying so be sure to moisturize your hands afterwards.
- Spray on fabric and use it as a wipe to disinfect your mobile phone and other surfaces.
Please note that while hand sanitizers are effective, washing your hands with soap and water is a much efficient way of killing virus when it’s on your skin. Experts recommend using a hand sanitizer only when washing your hands isn’t a practical option.
