In this video:
* Brief info on COVID-19 and hand hygiene (skip to 1:20 if you're sick of this)
* What you need in a hand sanitizer to kill coronavirus
* Reviewing DIY hand sanitizer recipes that will and won't work
* Extra tips on using hand sanitizer
Note that pharmaceutical/cosmetic/food grade alcohols are safest for use on skin – use other grades at your own risk.
I do not recommend using methylated spirits that contain methanol (many but not all of them do).
Some of the hand sanitizer recipes I've come across show some disturbing lack of comprehension of what we're up against. For some reason, people who can't calculate percentages or spell “coronavirus” still felt that they were qualified to make up their own pandemic-halting hand sanitizer recipes. Phrases like “this has worked for me for years” and “you can adjust how much alcohol you want to use” were frighteningly common.
This is a novel coronavirus, so information is limited at the moment – the info in this video is current as of 15 March 2020.
