How long can the new coronavirus live on a surface, like say, a door handle, after someone infected touches it with dirty fingers? A study out this week finds that the virus can survive on hard surfaces such as plastic and stainless steel for up to 72 hours and on cardboard for up to 24 hours . . .
. . . And given that wipes are hard to come by at many stores at the moment, you can instead buy an EPA-registered disinfecting spray, such as one on this list from the Center for Biocide Chemistries, recommended by the Centers for Disease Control and Prevention and by Dr. David Warren, an infectious disease specialist at Washington University School of Medicine in St. Louis.
Or make a bleach-based spray yourself. You can make a DIY cleaning spray by mixing 4 teaspoons bleach per quart of water, according to the CDC.
