Rubbing Alcohol

[Tartar Horde]

The backwoods hillbilly method is to run your product, knowing the first run will not be used. You pour off the methyl and run it again.

The second run will be tested for strength by the old gunpowder and match method. If it does not burn and flash the powder it is not strong enough. Run it again.

When it flashes off the powder it will be usable. The quicker it flashes the powder the stronger the proof. If you want it stronger run it again.

For killing germs, especially virus, you want it up above 100 Proof at the 50% level. That is going to take a couple of runs and you loose a little each run.

We use Hydrometers and refractometers these days Mort, much more reliable than Hillbillies, gunpowder and High proof hooch, which I'm sure you agree is a volatile combination.
