What you NEED to know about hand sanitiser: Doctors reveal if it’s safe to use year-old products

What you NEED to know about hand sanitiser: Doctors reveal whether it’s really safe to use your old bottles – and when you must get rid of them

  • Doctors have revealed why you need to pay close attention to expiry dates
  • If your hand sanitiser is out of date, it could be almost totally ineffective
  • The CDC still recommends washing your hands over using hand sanitiser
  • People should scrub their hands for 20 seconds to ensure they’re fully clean

Doctors have revealed why you need to pay close attention to the details on your hand sanitiser bottle – and how using expired products could render them almost ineffective.

According to Healthline, the average shelf life of hand sanitiser is somewhere between two and three years – so if you have a little bottle lurking at the bottom of your handbag and you can’t read the font on it because it’s rubbed off, the chances are it’s time to toss it.

‘The active ingredients are only guaranteed effective until the expiration date,’ Dr. Andrew Alexis, MD, chair of Mount Sinai’s department of dermatology, told Women’s Health. 

‘There are no clear visual signs of expiration so checking the label is the only reliable way to tell if that bottle deserves to be tossed.’

How does hand sanitiser work?

The alcohol in hand sanitiser disrupts the outer coating of many, but not all, germs; the CDC recommends using a hand sanitiser that contains at 60 per cent alcohol to ensure effectiveness.

However, these products are not very effective against bacterial spores or against viruses that don’t have an outer envelope. Sanitiser is effective against almost everything else.

Sales of hand sanitiser have soared in recent weeks, as people rush to get their hands on antibacterial products to prevent the rapid spread of coronavirus. 

The CEO and founder of Australian skincare range, Moogoo, told FEMAIL that their entire six-month stock of anti-bacterial hand gel has been snapped up in just four days. 

While doctors agree that ‘something is better than nothing’ and you can continue to use hand sanitiser once it’s past its best, they highlighted that it’s not always a good idea.

This is because the active ingredient is alcohol, and once it has been exposed to air – even indirectly through the protective bottle – it will become less and less effective.

Coronavirus essential guide: Your top hygiene questions answered 

Does hand-washing really work?

Yes. A new study published by the highly-respected Cochrane Database which summarises and interprets numerous studies says that handwashing cuts the chances of contracting a respiratory illness such as coronavirus by 54 per cent – the best odds of any deterrent.

So wash your hands – scrubbing every bit of skin from your wrist downwards – at every opportunity for at least 20 seconds (or for however long it takes to sing Happy Birthday in your head twice).

Should I use public transport? 

Only if necessary. If you can work from home rather than commuting, and also minimise shopping trips, you will greatly reduce your infection risk.

One recent study in Nottingham found that people who contracted the flu virus in 2011 were nearly six times more likely than others to have travelled by public transport in the five days before developing symptoms.

 lanes, trains and buses are high-risk environments for easily transmitted viruses – and Covid-19 is particularly infectious – to spread on to our hands via surfaces such as handrails, seats and handles.

If I stay at home will I be safe?

No. Family and friends can easily bring in the virus. To reduce this threat, institute a handwashing rule for everyone as soon as they enter the house.

And make sure there is one hand towel for each person. If that’s not practicable, wash towels frequently.

When it comes to hand washing versus hand sanitiser, all of the experts agree that your go-to should always be washing your hands. 

What is the five-step process to perfect hand washing?

1. Wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap.

2. Lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails.

3. Scrub your hands for at least 20 seconds. Need a timer? Hum the ‘Happy Birthday’ song from beginning to end twice.

4. Rinse your hands well under clean, running water.

5. Dry your hands using a clean towel or air dry them.

The CDC recommends that you scrub for at least 20 seconds (or for the time period that it takes you to sing Happy Birthday twice) and washing your hands is always better than hand sanitiser.

This is because hand sanitisers do not get rid of all types of germs, and they may not be as effective when your hands are dirty or greasy.

‘They might not remove harmful chemicals from hands like pesticides and heavy metals,’ the website reads. 

The agency recommends you wash your hands at frequent intervals to stay healthy, and advises that everyone follow five steps to ensure they are washing their hands the right way.

‘The first step is to wet your hands with clean, running water (warm or cold), turn off the tap, and apply soap,’ the CDC said.

‘Then, lather your hands by rubbing them together with the soap. Lather the backs of your hands, between your fingers, and under your nails.’

However the third step is where many people might be falling down.

The CDC recommends you scrub your hands ‘for at least 20 seconds’ – which is the same amount of time it takes to hum Happy Birthday twice.

‘Rinse your hands well under clean, running water,’ the guide advises.

Finally, you should use a clean towel to dry your hands or air dry them.
