Making your own hand sanitizer if there is none left in the shops.... Answered
For some unknown reason around here all shops are out of hand sanitizer.
My sister needed some as three kids just make it a requirement thanks to Corona.
Had to be cheap and plentyful she said....
Methylated spirit is still freely available in bulk at the hardware store, so I grabbed some.
Had no Calcium Acetate at hand so I ordered 200g online, it E263 if I recall correctly, a food additive.
To give it a nice smell I added some natural pappermint oil to the list.
The making is dirt simple....
For every 100ml of alcohol add about 20ml of filtered water - you don't want it full strenght.
Give a few drops of your favourite scent to it.
Then slowly add some Calcium Acetate and keep stirring.
Once the mix reaches the desired consistency of a more or less runny gel you are set to go.
How easy is that for a change?
Oh, in a hurry and no Calcium Acetate available anywhere? No problem!
Use egg shells and vinegar.
About 70g in egg shells should do for a good amount of sanitizer.
Use a large (high) pot and add about 400ml of vinegar to it.
If you can get the cleaning strength then better.
Add the crushed egg shells and keep stirring.
It will foam up, so add them slowly!
You need to keep stirring as the shells tend to float up with the produced CO2.
If no shells dissolve anymore add some more vinegar.
At the end you want to have some leftover shells but no more bubbling to indicate all the acetic acid from the vinegar was used up the reaction.
Filter through a coffe filter, or several layers of it to get a clean solution.
Bring it to a boil to get rid of the water.
Once you get a paste in your pot turn the heat off and remove the stuff from your pot to air dry.
If in a hurry, then spread it out on some baking paper and place at about 120°C in your oven to fully dry.
Crush up in a bag once cool and you have the Calcium Acetate you need ;)
