I am still on my first 10 pack of surgical face masks acquired last April . Since I am retired, I just use them to shop. I wear the masks briefly to shop and then steam clean them for 10 minutes or so. I keep about 5 masks in the rotation. I am just about ready to open my second 10 pack of face diapers. So far so good.
I have been wearing the same cloth mask since last March
in order to be allowed to get into the stores
that I want to go into.
Never have washed it...
