The world is weird right now. Rightly so. There’s never been anything like this. The world has shut down.
Everyone seems to be getting serious cabin fever due to the lockdowns, the shelter-in-place orders, the social distancing. Initially, I was confused by this. Then it hit me: everyone lives a dramatically different life than I do.
I’ve been seeing a lot of DIY hand sanitizer recipes lately, thanks to the novel coronavirus (covid-19). Unfortunately, a lot of the DIY recipes leave you with a product that is less than the CDC recommended 60% alcohol. I want to share why and how that happens, and give you a basic recipe to make your own hand sanitizer that follows the CDC guidelines.
First, it’s important to understand what your bottle of rubbing alcohol is: a bottle of 100% isopropyl alcohol and water. “Wait, my bottle says 70% rubbing alcohol!” I assure you, it’s still 100% alcohol mixed with water. Imagine an empty bottle, now put pure (100%) alcohol into the bottle, but only fill it halfway. Now fill the bottle the rest of the way with distilled water. You now have 50% rubbing alcohol because the solution (two or more things mixed together is a solution) is made up of 50% isopropyl alcohol and 50% water.
