Hand sanitizer is convenient, but using it correctly isn’t quite as simple as squirting some on your hands and moving on. The CDC recommends taking the following steps:
• Put sanitizer on your hands and rub them together
• Cover all surfaces of your hands until they feel dry
• This should take around 20 seconds
It’s also important to wash your hands with soap and water if they’re visibly dirty, says William Schaffner, M.D., an infectious disease specialist and professor at the Vanderbilt University School of Medicine.
You should choose an alcohol-based hand sanitizer that’s at least 60 percent alcohol, Dr. Schaffner says. “That will work when it comes to coronavirus and will also help protect against the flu and other germs that are floating around in the environment,” he explains.
