Alcohol disinfectants are most effective if contact time is maximized by allowing them to evaporate. So, skip the wiping down if you can.

Yeah if you buy 90% alcohol and mix it with aloe gel, it makes a decent hand sanitizer.
I can't find sanitizer anywhere, so I may opt for this route. It's convenient having a small bottle for when you're out and about touching all kinds of nastiness.
About five or more years ago, I bought a gold fish bowl of small hand sanitizers at the local Costco business center. Probably intended for convenience stores. I still have about half of them. They are past their expiration date, but since I can still smell alcohol in them I think they are effective. On those that have lost volume, I top them off with some 91% isopropanol I have handy. Also have a little spray bottle I fill with 70% isopropanol, and use that to spray down packages, door handles etc.

Re: Social Distancing 1A
If you dilute the 90% alcohol with some other medium like aloe gel, it should still be above 60% provided you keep the correct measurements. You'll be left with a nifty little hand sanitizer.Ulysses wrote: ↑Tue Apr 14, 2020 9:55 pmThe recommendations I've read for hand sanitizer are "at least 60% alcohol".

Re: Social Distancing 1A
It’s a general rule for any disinfecting with any product and for any pathogen, not specific to alcohol and coronaviruses, though some disinfectants are harsh enough that you do want to wipe/rinse them off after their recommended contact time has been realized.

Gasoline evaporates pretty fast as well. I never wipe after rubbing down with 93 octane. Plus gasoline doesn't dry your skin out like alcohol.

Remember when Trump talked about dropping a nuke on a hurricane to stop it in its tracks.
wouldn't that also work in stopping the COVID-19?

Re: Social Distancing 1A
I never asserted that gasoline is a disinfectant, lousy or otherwise. As far as I know, nobody else has made the assertion that it is either. I just commented on how quickly it evaporates; likely much faster than alcohol, but I have not researched this. I do know that if you look at two containers, one of alcohol and one of gasoline, at a perpendicular angle to those containers, you will not see anywhere near the "invisible smoke" (volatility) from the alcohol that you will see emanating from the gasoline. This indicates the gasoline is evaporating at good speed. As for whether microbes grow in gasoline or in alcohol or piss, I have no input on that. Gasoline will become "gummy" if left in a sealed container for long time periods; I don't know if alcohol or piss will do the same.Ulysses wrote: ↑Thu Apr 16, 2020 7:50 amIf I'm not mistaken, gasoline is sort of a lousy disinfectant.Vrede too wrote: ↑Wed Apr 15, 2020 8:41 amIt disinfects even better and dissipates faster if you put a match to it.neoplacebo wrote: ↑Wed Apr 15, 2020 8:08 amGasoline evaporates pretty fast as well.

I remember reading long ago that a big problem with old gasoline is that certain microbes grow in it and break it down into compounds that will foul an internal combustion engine.
Similarly, human urine, upon standing long enough, will grow various microbes that break the urea in urine down into ammonia, which is an efficient grease cutting cleaner. Ancient Greeks and Romans took advantage of that; they collected, stored, and utilized such aged human urine for their laundry works and for tanning hides.
However I'm not suggesting that you pee on yourself any more than already occurs.
Unless you happen to enjoy that kind of action, like our Fearless Leader. NTTAWWT.

Re: Social Distancing 1A
Touche; I guess. That response you quoted is not one I consider relevant, as it was made in jest. I was replying to what I assumed was your serious assertion about the anti bacterial properties of gasoline. And if you just called me a welp (whelp) I will invent something to call you; if you only misspelled the word "well" I will forget about it and not call you anything.Ulysses wrote: ↑Thu Apr 16, 2020 9:21 amWelp, please calm your troubled mind.neoplacebo wrote: ↑Thu Apr 16, 2020 9:05 am

I never claimed that you said gasoline was a disinfectant of any kind.
However, Vrede did assert that gasoline "disinfects even better" if ignited. That is what I was responding to:
Now, mind you, nobody in their right mind would suggest lighting an application of a highly flammable substance to make it an "even better disinfectant". But perhaps that excludes Vrede? Might cast a whole new light on the practice of burning suspected witches in times gone by. Perhaps it could be defended today as public sanitation?

In context it was a reasonable assumption since the alcohol evaporation tangent was all about disinfecting.

As I just explained and you even quoted I was clearly assuming, apparently incorrectly, that neoplacebo was jokingly referring to gasoline as a disinfectant, and I added an obvious joke on top of that.

Anyway, the big trend now is complaining about the lockdown. Saying just let everyone her infected to achieve herd immunity. Saying the response we've had is too much. Sharing memes insinuating that almost any death now is being attributed to the corona virus.
