No Sink? Try Hand Sanitizers
When you don’t have access to a sink, use alcohol gels and wipes. The alcohol kills most bacteria and viruses, but unlike antibacterial soaps, it can’t promote resistant bacteria. Note that alcohol is very drying to the skin, and washing with plain soap and water is just as effective at getting rid of germs. If you do use one of these products, make sure it contains at least 60 percent alcohol.
