Q: Can hand sanitizer replace hand washing? A: Without any cleaning, it is indeed better to use hand sanitizer before eating than to eat directly. However, the preferred method of handwashing in daily life is still running water and soap. Because the premise of using hand sanitizer is that there are no obvious visible stains on the hands. When we are away from home or busy at work, we may often not have the conditions to find a running water source to wash our hands at any time. For ordinary people, it is fine, but for most mothers, this is a big problem. After all, the frequency of cleaning hands will be higher after having children. Many, some mothers will choose to bring a large pack of wet wipes, but the weight is quite heavy.
