One YouTube video that touts a concoction of witch hazel, tea tree oil and aloe vera has been viewed 1.8 million times. Another YouTube video, viewed 747,000 times in the past two weeks, recommends isopropyl rubbing alcohol with concentrations as low as 70 per cent — a level that, when mixed with the other ingredients, wouldn't be enough to kill the virus.
The World Health Organization's website has legitimate instructions for making hand sanitizer that recommend using ethanol with a concentration of 96 per cent, or isopropyl alcohol with a 99.8 per cent concentration.
Experts say the best way to kill the COVID 19 virus on your hands is to wash them properly with soap and water. If that's not an option, an effective hand sanitizer should have an alcohol concentration of at least 60 per cent.
