What do you do with that contaminated snot rag when you take it off your face?
If COVID is such a serious disease then why are you not using a fresh mask every 20 minute per manufacturers recommendation and using a receptacle to dispose of those contaminated masks?
It seems that the waste receptacle is the gutter around here.
I wash it with soap. Soap kills covid virus better than sanitizers. Because soap dissolves the protective fat layer on the virus cell. I have a dozen or more masks.
