Many people want to know how to clean masks, especially now that the Centers for Disease Control and Prevention (CDC) is everyone wear cloth masks in public.
Pat from Olympia asked: "Could a person safely kill the coronavirus on homemade face masks in an electric pressure cooker that's normally used for cooking, such as an Instant Pot?"
A study from Case Western Reserve University and Louis Stokes Cleveland VA Medical Center doctors found steam from rice cookers is an effective way to decontaminate some face masks.
There鈥檚 been advice on the internet for at-home sterilization, like putting masks in the microwave, but just because extreme heat from steam could potentially kill viruses, doesn't mean you should try it at home, says Dr. Nikita Desai from the Cleveland Clinic.
"It's very difficult to achieve the standards of humidity, temperature, length of time, and sterility that you need to completely sterilize something at home," Desai said.
Soap and water does the trick for washing fabric masks, which a person can do in a sink or in a washing machine, said Case Western Reserve University鈥檚 Dr. Scott Frank. He said the temperature of the water doesn鈥檛 matter 鈥 it鈥檚 the soap that鈥檚 important.
鈥淭he virus is constituted by a lining that is essentially fatty in nature and easily dissolved by soap,鈥 said Frank.
In addition to this, he said any other method of cleaning masks could destroy the material, or worse, start a fire.
Frank said he wouldn鈥檛 want to eat out of a pressure cooker that鈥檚 had a face mask in it either.
