Can hand sanitizer be effective against coronavirus? Lifehacker says yes, while the CDC specifically recommends using a hand sanitizer that contains at least 60 percent alcohol. That’s because alcohol is found to disrupt the coronavirus’ outer coating (which isn’t the case for all germs).
However, whenever possible, hand-washing with soap is still the best way to combat coronavirus, colds and everything else. Scrub hands for 20 seconds–or about as long as it takes to sing “Happy Birthday.”
