Coronavirus: Washing clothes at 30 °C ‘won’t kill the virus’
China tells residents to wash items at 60 °C ‘Celsius’ to kill coronavirus – tips shared with world
CORONAVIRUS may have broken out in China but it is now unleashing chaos around the world, with Europe branded the “epicentre” of the outbreak. China appears to have got a handle on the crisis – is there anything we can learn from their approach?
Coronavirus’ destructive effects are in some respects analogous to what we see in wartime, with an ever-rising death toll, country-wide lockdowns and a tumbling stock market. Meanwhile it appears China has largely got a handle on the pandemic, with new cases plummeting in the last couple of weeks. While much is still to be established about the pathogen, what has China learned through its response so far?
Dr Li Li, Clinical AI Researcher and GP, has been updated on China’s response through doing translation work for a coronavirus course based on the first hand experience in China.
As Dr Li Li reports, according to the official guidance published by the National Health Commission in China (the equivalent body to the NHS England), the virus can’t survive if it is exposed to 56 degrees after 30 minutes.
“So in China, the empirical approach is to wash at high temperature of 60 C, for longer than 30 minutes,” she explained.
According to Dr Li Li, dryers on high temperature setting usually generate heat up to 68 C.
Therefore, according to the recommendations put forward by Chinese health officials, 30 mins or more will also help to kill the virus.
How long does the virus survive on different materials? What we know so far
According to Dr Li Li, the virus survives the longest (up to two to three days) on metal and plastic surfaces.
“So buttons on lifts, door handles are the most infected surfaces,” she said.
How has China responded to this?
According to Dr Li Li, most lifts are now equipped with a box of tissues and a bin so people can use the tissue to touch the button and bin the tissue after use.
“This procedure is also suggested when people use the toilet, after they wash their hands and dry them with a paper towel, reuse the towel to open the door and bin the towel afterwards,” she said.
What about materials?
There is no published study on how long the Covid-19 can survive on fabric.
There is research published on how long similar viruses have survived on fabrics, however.
A joint study published in the American Journal of infection control on influenza A ( H1N1) showed that the virus can live on a cloth surface for up to eight hours.
Similar viruses seem to hang around soft toys from anywhere between four and nine hours, noted Dr Li Li.
“Other fabric such as J cloth have short virus survival time of around four hours,” she said.
Paper money can carry virus much longer, added Dr Li Li.
The swine flu survived on banknotes for three to 17 days, she noted.
Other key tips to reduce the risk of catching and spreading the virus
The most important step is to wash your hands with soap and water often – do this for at least 20 seconds.
According to the NHS, you should repeat this practice when you get home and into work.
Other key tips include:
Use hand sanitiser gel if soap and water are not available
Cover your mouth and nose with a tissue or your sleeve (not your hands) when you cough or sneeze
Put used tissues in the bin immediately and wash your hands afterwards
Avoid close contact with people who have symptoms of coronavirus
Only travel on public transport if you need to
Work from home, if you can
Avoid social activities, such as going to pubs, restaurants, theatres and cinemas
Avoid events with large groups of people
Use phone, online services, or apps to contact your GP surgery or other NHS services
“You should also avoid touching your eyes, nose or mouth if your hands are not clean,” advised the health body.

As a follow on, it appears according to Which.co.uk that the use of Biological washing powders helps on the reduction of Corona virus on clothes during washing
Coronavirus: How to wash clothes and kill germs Germs can spread via clothes, particularly if you’re sharing towels, so follow these key tips to minimise the risk if you’re living with someone who is self-isolating or at risk
COVID-19 can enter the body and infect someone through the mouth, eyes or nostrils. This is why you need to wash your hands more often and avoid touching your face. If you’re handling clothes of someone who has been experiencing coronavirus symptoms, make sure you don’t touch your face and be sure to wash your hands afterwards. Also avoid shaking up any laundry too much, otherwise you could be spreading the virus through the air. The current government coronavirus advice for people with confirmed or possible COVID-19 infection says: You can wash items just as the manufacturer’s instructions say, as you normally would. Dirty laundry that has been in contact with an ill person can also be washed with other people’s
The NHS lays out some exceptions that you may want to wash separately, at a higher temperature and with a bleach-based detergent – such as a biological powder for whites.
Wash these at 60°C with a powder detergent Sports kit
Clothes which come into contact with a lot of bodily fluids, such as sportswear, will have a great number of germs on, so could pose a greater risk. Also avoid wearing sportswear more than once between washes. Towels Shared towels in your home can harbour many germs, so could quickly spread coronavirus. Wash shared towels often and at 60°C . If there is someone who is self-
Baby clothes and reusable nappies Any items that come into contact with vomit or faeces are a germ risk. The most common of these will be baby clothes, which you’ll need to wash separately at 60°C to avoid spreading germs to your child.
Do antibacterial washing machine cleaners kill coronavirus?
Coronavirus doesn’t mean you have to worry unduly about cleaning your washing machine. Simply following the clothes washing advice above should be sufficient. You can continue to clean your washing machine as you normally would to keep it running smoothly. Dettol and Dr Beckmann washing machine cleaners both claim to kill 99.9% of bacteria. All washing machine cleaners should kill bacteria, though, thanks a variety of anti-bacterial ingredients, most commonly oxygen-based bleaching agents. Don’t use regular household bleach to clean your washing machine, as this can damage and erode the rubber seals inside. Read our washing machine cleaners compared guide to find out more.
What about if I need to go to the launderette?
If you don’t have the luxury of your own washing machine, the government warns that you need to wait a further 72 hours after your seven-day isolation period has ended before going to the launderette. You might also want to follow this guidance if you normally use a shared washing machine in a block of flats, for example.
