Hand sanitiser is a liquid or gel used to disinfect hands and reduce the spread of germs, bacteria, and viruses.

Hand sanitiser contains alcohol (usually between 60% and 95%) that kills germs on contact. When you rub hand sanitiser onto your hands, it breaks down the outer layer of the germs and viruses, rendering them inactive and unable to infect you.

Apply a small amount of hand sanitiser to the palm of one hand and rub it all over the surfaces of both hands, including the backs of your hands, in between your fingers, and under your nails. Rub until the hand sanitiser dries completely.

Hand sanitiser is generally safe for use, but it should not be ingested or applied to the eyes or mouth. If ingested, seek medical attention immediately. If hand sanitiser gets into your eyes, flush them thoroughly with water.

The recommended alcohol content for hand sanitiser is between 60% and 95%. Hand sanitisers with less than 60% alcohol may not be effective in killing germs.

Yes, hand sanitiser can expire. Most hand sanitisers have a shelf life of two to three years. After that, the alcohol content may start to break down, making the hand sanitiser less effective.

Hand sanitiser can kill most germs and bacteria, but it is not effective against all types of viruses. For example, hand sanitiser may not be effective against norovirus, a common cause of stomach flu.

Hand sanitiser is not a replacement for hand washing. While hand sanitiser can kill germs on your hands, it does not remove dirt, grime, and other contaminants. It is important to wash your hands with soap and water for at least 20 seconds before using hand sanitiser.
