Question: How long does it take to clean after you have squirted all those viruses?

Ruth Elderfield answered on 15 Jun 2015:

When cleaning up after viruses we have to know how the virus is made up.
Some viruses just need a little bit of alcohol on them for a few seconds and they fall apart, others need to be dipped in bleach for 10 minutes before they will die. We test how long it will take to stop the virus very carefully before we do any other work with it, then we usually add extra time just to be absolutely sure. We don’t want to get sick!
