There are so many hand sanitizers in the market. We must use a Sanitizer having Alcohol above 70%. Take About 3ml & RUB on the hands on front & back in between the finger, under the finger nails, till all the alcohol is evaporated.
In case Sanitizer is not available or you have some allergy then use any soap in a quantity which will produce sufficient foam & rub thoroughly & wash for 20 seconds
