Since the start of the coronavirus pandemic last year, hygiene has been a hot topic and it's only become more important now that news of a new variant is dominating the headlines. We all know that simple personal hygiene measures such as hand washing, wearing a face covering and using a hand sanitiser when we're out and about can help stop the spread of this and other illnesses. But what can we do to protect ourselves at home?

Just over half of us in the UK say we are more concerned about the cleanliness of our homes than we were before the outbreak of the virus, research by cleaning product company Hydrachem has shown. The same poll shows that almost 60% of us are spending an additional hour cleaning our homes each week but a third of us are unsure if the cleaning products we're using are actually effective in killing the virus.

So how can we be sure that the extra time we're spending cleaning is actually helping to protect us and our families from COVID-19 and other germs? Here’s the cleaning knowledge you need to keep bacteria and viruses at bay in your home.

1. Clean then disinfect

Use a two-step method – cleaning first then disinfecting – to tackle surfaces such as kitchen counters, table tops and bathroom surfaces or other 'high touch' surfaces. To clean, either spray the surface with distilled white vinegar and then wipe down with a clean cloth or simply use a microfibre cloth with warm water, or a cleaning cloth dipped in detergent solution and wrung out fully.

To disinfect against both the original and the new strain of Covid-19, Middlesex University immunologist Dr Darshna Yagnik has the following advice: ‘The highly infectious mutant coronavirus can still be inactivated efficiently by regular disinfection using products containing at least 70% alcohol, 0.5% hydrogen peroxide or bleach (diluted to 0.1% sodium hypochlorite) using cold water.' That's around 50ml of thick household bleach diluted in just over 2 litres of water.

2. Make your disinfectant work harder!

How effective a disinfectant is at killing germs and viruses doesn’t just depend on its ingredients – the length of time it is left to work (known as ‘contact time’) also comes into play. ‘This ‘contact time’ is needed to get the most out of your disinfectant,’ explains microbiologist and author of The Germ Code, Jason Tetro. ‘Use a product that claims to kill 99.9% of bacteria and viruses, and ensure you leave it to work on a hard surface for at least one minute but preferably three minutes.’

3. Don’t overlook ‘high touch’ surfaces

It’s easy to remember to clean and disinfect obvious germ hotspots such as the toilet and kitchen surfaces. But other frequently touched surfaces in our homes need attention, too – think door and kettle handles, light switches and bannisters.

If using bleach, ensure to rinse the area you are cleaning after applying it, ensuring you leave it to work for at least a minute. For obvious electrical safety reasons, you should never spray anything directly onto a light switch. Instead, make up a disinfectant solution in an old spray bottle and spray this lightly onto a microfibre cloth, then use this to wipe the switch and switch plate. Buff with a clean, soft cloth or a fine microfibre cloth for a satisfying shine.

If someone in your household has coronavirus, the NHS recommends you clean the bathroom after they've used it, if other people use that bathroom, too.

4. Leave your shoes by the door

Shoes don’t just carry dirt into our homes – they also have the potential to introduce germs. For this reason, it’s best to make your home a ‘shoes-free’ zone and to clean hard floors regularly, says Verity Mann, ‘Start by vacuuming or sweeping hard floors to get rid of loose dirt then mop with a warm solution of disinfectant,’ she advises. ‘Take care not to over-wet laminate flooring as this could cause it to warp.’

GHI TIP: If you have vinyl flooring, it’s best to follow the manufacturer’s cleaning advice, which may recommend using a specialist product or avoiding some cleaners altogether. If you don’t, you risk invalidating any warranty the flooring is covered by.

5. Pay attention to shared devices

Tech that’s used by the whole family, such as the home phone, remote controls, computer keyboards and games console controllers, may also be microbe-magnets. To clean them, start by removing dust with a soft cloth, then use a microfibre cloth sprayed lightly with water to wipe away grime, followed by a clean cloth spritzed with a disinfectant solution to get rid of germs and viruses. A cotton bud can be handy to clean the small areas between buttons.

6. Clean cleaning cloths thoroughly

When it comes to hygienic cleaning, a ‘one cloth fits all’ approach is no good. If you use cloths and sponges to clean, switching to a clean one when you finish cleaning one surface and before you move on to another will help stop the spread of bacteria and viruses.

If you use microfibre cleaning cloths, manufacturers such as e-Cloth say that rinsing them regularly and thoroughly under warm, running water while you clean is enough to get rid of almost all the bacteria that may have built up in the cloth. In theory, this should mean you can carry on using the same cloth for longer before switching to a clean one. We wouldn’t recommend using the same cloth in different rooms, though, and e-Cloth doesn’t make any claims about how effective its cloths are at tackling viruses.

Microfibre cloths will clean most effectively when you use them with warm or hot water (this helps open out the fibres) and when you fold the cloth into a pad, which helps the cloth make the best possible contact with the surface you’re cleaning. Microfibre cloths will still need machine washing at the highest temperature possible after you finish cleaning, just like other cloths.

7. Use steam power

Steam is a great ally when it comes to killing germs, and can help lift dirt and grime at the same time. Steam cleaners can be used on a range of waterproof, sealed surfaces around the home – so not wooden floorboards, for instance – and with the right attachments they can also be used to clean ovens and hobs, too. Again, if you have vinyl flooring, check the flooring manufacturer’s guidance first.
