Sanitisers & Sanitising Agents
Hand sanitisers are commonly used where users need to apply a sanitiser to kill bacteria. Dirt should be removed first, or the dirt acts as a barrier between the sanitiser and hands. Sometimes hands are sanitised where cleaning stations are not available - like at a school classroom entrance, and if paper towel is available the sanitiser can act to assist dirt removal too.
Sanitisers will remove 999 germs in 1000 to be called a sanitiser. For hand sanitisers, they will be more gentle than surface sanitisers.
