When was the last time you gave thought on how to wash your hands? Turn the tap on, add soap, rub and rinse. What’s to think about? According to science – A lot. If you really want to get your hands clean and germ free you need to be following the 6 (yes 6) step method to the best way to wash your hands according to science.
Researchers at the Glasgow Caledonian University compared two methods and discovered that one of them reduces bacteria count from 3.28 to 2.58 whilst the other method takes it down to 2.88.
The two methods were the 6 step method recommended by the World Health Organisation and the Three step method, recommended by America’s Centre for Disease Control & Prevention. The winner? The World Health Organisation’s 6 step method which although takes longer (and additional 7.5 seconds on average) will leave your hands more hygienic.

- Begin by rubbing your palms together with your fingers closed
- Rub your right palm over the back of your left hand, fingers interlocking. Then rub your left palm over the back of your right hand, fingers interlocking.
- Next, rub your palms together with your fingers interlaced
