Hand Washing with ‘Soap’ and Water is more effective than Hand Sanitisers in most cases

A recent study, ahead of the upcoming winter period when risk of flu is more prevalent, a scientist on BBC Breakfast TV stated that simple hand washing with warm water and soap alongside proper drying is the best way to keep germs at bay and reduce the risk of spreading germs.

Whilst hand sanitisers do ‘kill germs’ and are ideal in cases where clean water, soap and hand drying facilities are not available, if you have a choice of both, always choose the trusty soap and water solution.

When Hand Sanitiser is an alternative

In public places, especially hospitals, clinics and doctors surgeries, hand sanitisers are widely used and provide an effective hygiene solution. Health care professionals are required to keep their hands spotlessly clean and using hand sanitisers can assist in this.

Regular hand washing during the day is required and soap and water washing is not always feasible.

Hand Sanitiser Fact

Sanitisers will kill germs but will not remove dirt.

Some people have advocated that you should wash your hands after every four or five uses of alcohol-based hand rub. In reality, if your hands feel ‘grubby’ or are visibly dirty, you should wash them with soap and water.

How do Hand Sanitisers Kill Germs

Alcohol kills most germs on contact without causing serious harm to the skin tissue, which makes it an effective active ingredient for hand sanitisers. Ethanol and isopropanol are antiseptics that kill germs by dissolving their essential proteins.

Are Hand Sanitisers effective for all Germs?

No. Alcohol-based hand sanitisers do not kill germs such as MRSA, Salmonella, e. Coli or Norovirus.
