But, IME, once wet it returns to it’s normal flexibility (do you realize how difficult it was to formulate that response without opening up easy cheap shots - “Heh heh, mine usually gets hard and stiff when wet and limp when dry”)
And this is when I throw it in the laundry and grab a new one. I can usually get a week or so out of a washcloth between ‘formal’ washes. Maybe it is, at least partially, a function of where one lives and the humidity/temp in the bathroom.
A nice thick washcloth leaves me feeling a lot cleaner. I just hang it on a plastic hook and let it dry that way. After laundering they always smell fresh. I only use a washcloth for one shower, then it goes into the laundry.
