Observed at a branch of the Co-op, near the big signs enjoining customers to stay safe: window cleaning fluid as hand “sanitiser”. This contains no more than about 5% isopropanol, and less if they’ve watered it down. You need a level of about 60%. You’d probably literally be better off washing your hands in piss.
As for cloth masks, they give the wearer little protection from virus particles, although they do stop many of the bacteria and viruses that you breathe out, so they’re of some help to other people. Ever wondered why medics and nurses in hospitals wear tissue masks?
