Good old-fashioned elbow grease is the trick to cleaning effectively, Professor Collignon adds, because you are "physically decreasing the number of bacteria present and washing them down the sink". Then you have to ask yourself whether you need to disinfect at all," he says. "You've got to clean the surface first and that's usually enough. Rather than concentrating on disinfecting surfaces or exterminating all those nasty bugs, Professor Collignon says we should focus on cleaning with hot soapy water. Nevertheless, when it comes to cleaning the house, keep it simple. We asked if you used vinegar as a household cleaning agent. Indeed, it could even be an effective and economical solution to laboratories and hospital settings in resource-poor countries. Professor Peter Collignon, an infectious diseases physician at the Australian National University's medical school, says: "TB is a hard-to-kill bacteria, so the fact that it works against them means most other bacteria will likely be killed by vinegar as well." More recently, US researchers from the Albert Einstein College of Medicine found that vinegar efficiently killed Mycobacterium tuberculosis - the bacteria that causes tuberculosis - after 30 mins of exposure to a six per cent acetic solution. Science also tells us, for example, that vinegar will kill off the flu virus.Īs part of research aimed at preparing us for a flu pandemic, UK researchers found that malt vinegar, much like bleach and washing up liquid, can rapidly inactivate the flu virus. When US researchers tested commercial cleaning products against alternatives like vinegar and bicarbonate of soda, they discovered that neat vinegar killed a range of household pathogens. Some products take a long time to break down, and have unforeseen toxicities.
