Make Your Own Hand Sanitizer

DIY hand sanitizer ingredientsAs people will no doubt have found out, those members of our society who don’t wash their hands even after they’ve had a shit have been resolutely buying crates of hand sanitizer and thus preventing those of us for whom it might have some benefit getting any of it. In some cases, they’re selling it on eBay for stupid prices.

It’s actually quite easy to make your own. For hand sanitizer to sanitize, it needs to contain at least 60% alcohol. Vodka has been touted across the internet as a suitable makeshift option, but normal vodka is only about 40% alcohol, and it simply doesn’t work. You can get some spirits which are 96% alcohol (which people have died from by drinking it neat), but anyone who is stupid enough to pay how much they cost in the first place puts themselves on this year’s list of Darwin Awards candidates immediately. It would be cheaper to pay the extortionate prices for a faeces-covered rip-off on eBay, being sold by ‘stevethetwat99’ in Manchester (made up name, by the way).

You can use ethanol or isopropyl alcohol (IPA) as your sanitizer base. IPA is often also called ‘rubbing alcohol’, though the great unwashed appear to have latched on to it and have cleared out most stocks of that.

I use ethanol – to be specific, bioethanol – which is used as a fuel for stoves and such. I always have a supply because it’s what I use in my homemade screen wash as the antifreeze element.

You need the following:

  • a suitable plastic bottle
  • bioethanol or neat IPA
  • Aloe Vera Gel
  • Tea Tree Oil
  • Lavender Oil

I used a 250ml plastic bottle with a flip-top lid intended for hand creams (don’t ask why I have any of these in the first place).

Calibrate the bottle first. Pour in exactly 175mls (or grammes) of water. Mark the level with a felt-tip pen. Now add another 75mls (or 75 grammes) of water and mark that level, too. Empty the water away and shake any drips out.

Now you can make the sanitizer. Fill the bottle to the first mark with your alcohol. Then fill it to the second mark with Aloe Vera Gel. Add a few drops of the two oils (up to 10-15 of each, though neither is essential, and you can use anything you like the smell of as long as it’s only a few drops), then screw on the lid and shake well. It takes a while for the gel to disperse, but once it has your sanitizer is ready to use. This version contains 70% by volume of alcohol.

Be careful if you buy ‘rubbing alcohol’ as it is often already diluted to 70% and adding anything else will stop it sanitizing properly. It’s best to buy neat IPA, which is usually freely available as a cleaner.
