Need to know
- Clothes can carry the virus that causes COVID-19, but you're probably already doing everything you need to with your laundry
- There are things you can do to further minimise the risk, even when caring for someone who has caught the virus
Many germs, including the coronavirus that causes COVID-19, can be transmitted via contaminated clothing and towels.
Unfortunately, we don't know how long the COVID-19 coronavirus can live on fabrics, so it pays to take a few precautions.
The good news is, unless you're caring for someone who's infected or in a high-risk category, those precautions aren't too onerous.
Will my washing machine keep COVID at bay?
If you're dealing with lightly soiled items that you consider low risk (i.e. haven't come into contact with a known infection) then your current washing machine and normal laundry detergent are excellent tools in the fight against transmission. The combination of detergent, hot water, agitation, rinsing and spinning that's part and parcel of your existing laundry routine is very effective at rendering inactive, removing and flushing away viral loads.
According to the National Health Service (NHS) in the UK, where they're dealing with many more cases than we are in Australia, "normal washing of clothes will reduce the risk of germs being transmitted".
Even if you have extra reason to be concerned – for example, you may have come into contact with the virus – you don't have to change your laundry routine much to stay safe. According to the NHS, "in certain situations clothes should be washed at higher than normal temperatures and with a bleach-based product to minimise the transmission risk as much as possible."
How to do your laundry during the pandemic
Here's how to wash your clothes and other items to help reduce the risk of exposure to the COVID-19 virus.
Wash on the hottest program your care label recommends
While we normally recommend washing in cold water, heat is one of the best ways of rendering viruses inactive. If you're washing by hand, make it as hot as you can stand.
High-risk clothing should ideally be washed at 60°C or above.
Wash high-risk clothes at 60°C or above
Clothing that's been exposed to bodily fluids – such as blood, vomit, sweat and faeces, including clothing worn over an open wound and communal towels – can spread viruses readily. This means you should wash your workout gear, towels, underwear and especially reusable nappies and baby clothes at 60°C or hotter.
Heavily soiled items and clothing used in food preparation should be washed separately, and even though you're now exercising on your own, don't re-wear your smelly gym clothes – put them straight in the wash.
Consider using bleach
Follow the dilution instructions on the bottle and not only will bleach help keep your whites their whitest, but according to the International Scientific Forum on Home Hygiene, it may help render viruses inactive in the wash. Many laundry detergents already contain colour-safe bleaching agents, so check the box or bottle in your laundry, and if yours doesn't, consider switching to one that does.
Don't share towels
Sharing towels is a hygiene horror story, and one of the easiest ways to spread germs from person to person. And this includes hand towels tools too – even if you have just washed your hands for the requisite 20 seconds.
Dry laundry thoroughly after washing
Viruses spread more easily via wet surfaces than dry ones, so make sure your laundry's completely dry after washing to minimise the risk of contamination. And while we usually advocate line drying if possible, this is one time where deferring to the dryer might be of benefit. Despite sunlight's mild germ-killing properties, the hot air in your dryer will do a much better job at rendering viruses inactive.
How do I wash my face mask?
If you choose to wear a face mask (and gloves for that matter), then you should change it often. Face masks can quickly build up large viral loads as they have warm, moist air (your breath) constantly moving through them. Think of wearing a contaminated mask as the same as holding a damp cloth soaked in germs to your mouth and nose and you'll see why it's a problem.
If you do choose to wear a mask or other facial covering, then change it regularly. Fabric masks should be washed in hot water, and dried thoroughly before you wear it again. Disposable masks are strictly single use, so throw them away (responsibly) after use.
Extra precautions for someone with COVID-19
Doing the laundry safely is particularly important if someone in your household might have the virus (confirmed or suspected), is in a high-risk category (such as those with a compromised immune system), or is a frontline care worker who is likely to come into contact with the virus.
The above washing practices are effective in rendering contaminated clothing safe (and you should consider all clothing, towels and linen used by these groups as contaminated), so it's fine to combine contaminated clothing with your regular clothes in the machine, but there are a couple of additional precautions you should take.
Handle contaminated clothing with care
The United States' Center for Disease Control and Prevention (CDC) recommends wearing gloves when handling contaminated clothing, particularly if it has come into contact with bodily fluids. Dispose of gloves safely after loading the washing machine. Whether you're wearing gloves or not, be mindful of keeping your hands away from your face during the entire process, and wash your hands thoroughly with soap and water for at least 20 seconds afterwards.
Wash hot and with bleach
Wash contaminated clothing in hot water – ideally 60°C or above (provided it won't damage the fabric) – and use a bleach containing detergent, or if washing whites then add bleach to the wash itself (following the manufacturer's recommendation) for the best virus-killing performance.
Store contaminated laundry separately
While you're fine to wash contaminated clothing together with other items (unless it's heavily soiled), keep it in a separate hamper until laundry day. And on the subject of laundry hampers, do use one rather than the 'floordrobe', so contaminated clothes are put away safely. You should use a washable or disposable liner for that hamper, and change it when you wash.
Give flicking the flick
Do not shake out contaminated laundry – it can release viruses and other germs into the air. Carry contaminated clothing carefully and load your washing machine gently.
Sanitise contact surfaces
Once the laundry's on, clean and sanitise any surfaces you've had contact with in the course of doing the laundry – that includes the door and control panel of your washing machine, the laundry doorknob, and of course the hamper you've kept contaminated clothing in (and throw the hamper liner in with the wash too, if it's reusable) – using bleach or household disinfectant.
Change clothes early and often
If you're a frontline health worker or have likely come into contact with the virus during your day, then change clothes as soon as possible or at least as soon as you get home, and treat what you were wearing as you would other contaminated clothing. This minimises your exposure if your clothes do happen to have the virus on them.
Do I need a washing machine with a sanitise program?
For most of us, a regular wash with hot water and detergent will do a perfectly good job of getting your laundry clean and virus-free.
A sanitising washing machine is a washing machine with a special program that uses super-heated steam or water to kill off germs and bacteria in your clothes, sterilising them and leaving them smelling better.
They tend to be more expensive than regular machines and unless you're a frontline health worker, immunocompromised, or have a bad reaction to dust mites and the like (which sanitising programs kill as well) then your current washing machine's just fine.
Do I need to decontaminate my washing machine?
The same combination of hot water, detergent and agitation that releases viruses from your laundry and flushes them away should keep the insides of your washing machine virus-free.
While you can use bleach to sanitise the doors and controls, you shouldn't use it undiluted inside the machine at all (other than oxygen based bleaches as part of a wash cycle, following the manufacturer's instructions), as it can potentially damage rubber seals and hoses.
There are several commercially made antibacterial washing machine cleaners available, many of which use an oxygen-based bleach to kill most of the microbes that may have gathered. While this might give your washing machine a good spring clean, clearing out scrud and helping it work (and probably smell) better, it's worth noting that viruses and bacteria are two different things, so they may not help protect against COVID-19 anyway.
Can I carry the COVID-19 virus inside on my shoes?
Yes. Shoes can and do pick up all sorts of nasties (not just coronavirus), but you can consider them low risk because you typically don't put them on the dining table or in your mouth – you're already naturally treating them as dirty.
You can keep shoes clean the same way you clean and sanitise hard surfaces (wipes are good for this, and you can dispose of them after), but you can also kick them off outside so as not to track the virus into your home.
Can you still use dry cleaners, laundromats or shared laundry facilities?
Even in the age of social distancing, doing the laundry is a fairly low-risk activity. You're more at risk from someone coughing near you than you are of infection from touching surfaces, so a few simple precautions are all that's needed to protect yourself and others.
Sanitise hard surfaces
Treat communal laundry facilities the way you would if you were doing the laundry for a COVID-19 carrier at home, and sanitise hard surfaces – controls, washing machine lids and door handles – on your way in and out.
Practice social distancing
Stay 1.5 metres away from other people, and don't linger while you're waiting for your laundry to be done – go for a walk instead.
Wash your hands on entry and exit
Failing that, use hand sanitiser – just as you would when visiting any other establishment.
If you're self-isolating, then stay self-isolated
It should go without saying that if you're quarantined or self-isolating you shouldn't venture to the laundromat. Once your self-isolation has ended, you should still wait a couple of days before doing the laundry, because the virus can survive on clothing for a little while and this will reduce the risk of turning laundromat patrons into patients.
