This unique experiment reveals how long you should wash your hands for and how to wash your hands the right way.
The whiter the hand, the more bugs left after washing
BEFORE WASHING: Covered with germs - shown by the white glow
BEFORE WASHING: Covered with germs - shown by the white glow
RINSE AND SHAKE: You may be in a rush - but a splash of water won't shift the bugs
SIX SECONDS NO SOAP: The average wash - but vast patches of germs remain
SIX SECONDS WITH SOAP: Proof soap helps - but those fingers are still filthy
FIFTEEN SECONDS WITH SOAP: What NHS recommends - but germs still lurk on knuckles and nail cuticles
THIRTY SECONDS WITH SOAP: Almost spotless - but this is FIVE times longer than most of us wash
