My takeaway from
@Kayelle's awful experience (as referenced in post #20 above) is that we need to wash masks after every wearing, not only for possible COVID virus. The bacteria we breathe out can cause very nasty infections.
DH & I have three bowls for masks. My clean masks, his clean masks (bigger than mine - his head is larger) and dirty masks. We each have over a dozen cloth masks and don't go out that often, so I only wash masks about once a week.
I soak them in the sink with Dawn and hot water, then scrub them in a fresh batch of Dawn & hot water, rinse well, lay them out on a beach towel and let them air dry in the sun.
