Ridding your paws of germs is more about elbow grease than your choice of soap. “The purpose of soap isn’t to kill germs, but to remove them by friction,” says Dr Elaine Larson. If you want squeaky-clean hands, upgrade your washing technique. Wet your hands and lather the soap by rubbing thoroughly – palm to palm, between your fingers and on the backs of your hands.
Then, before you rinse, rub your fingertips into the suds on your palms; your fingernails are the biggest biological hot spots on your hands. The whole process should take at least 20 seconds.
