I just realised that 1l of 99.9% IPA that I bought as electronic cleaner for €5.95 a few months ago is now called SARS2-CoV desinfecant with a price tag of €70. Looks like I still have desinfecant worth around €40 in that plastic bottle 😜 #covid19
@przemo But… it's not SARS-CoV-2 disinfectant. It'd have to be diluted with (ideally distilled) water to 70% to be effective.
@wizzwizz4 How come? I'm open to correction, but I think it's about destroying the lipid coat on the virus, so 99.9% or 70% should work.
@przemo Yeah, but dehydrating the virus makes that harder. Osmosis.
If you've heard differently, then go with that.
@wizzwizz4 You might be right and it's a huge surprise to me: http://www.zadidoll.com/2016/08/disinfecting-70-ispropyl-alcohol-vs-99.html?m=1 I learned somethibg new - thank you for that!
Yeah. 70% for disinfecting, 99% for cleaning magnetic tape heads and any other electronics tasks that need a solvent but want minimal water.
Another interesting bit of trivia is that you can't buy 100% alcohol because, when alcohol's concentration goes above 99-point-something percent, it wants water in it so badly it'll pull it out of the air to reach that balance point. I forget what the technical term is.
