Check the active ingredient of your hand sanitizer. You may have one that contains benzalkonium chloride, which does not work against at least one type of coronavirus. (This turns out to be the case for one of the hand sanitizers I’ve been using.) Get one that has “greater than 60% ethanol or 70% isopropanol” instead, as recommended by CDC.
ETA: I didn’t bother to check this until today, because why would the FDA approve or fail to pull from the market, hand sanitizers that don’t work against an important group of viruses? And why hasn’t there been any articles in the MSM about this?
That study is on inanimate surfaces, and benzalkonium chloride is the main ingredient of Clorox, Lysol and other disinfectant wipes. So it might be a good idea to switch to isopropanol wipes for surfaces too.
I’m pretty sure this can’t be correct—they claim benzalkonium chloride has zero effectiveness, which is less than plain water! I think it has to be a data entry error.
This review cites some other studies that show benzalkonium chloride to be comparable to other disinfectants, although alcohol is still best by a considerable margin.
