Back in the day, we used cloth diapers. We flushed them out, or hosed them down, and then washed them.
And then I did my ex-wife's laundry before mine. Ladies first, and all that. ;)
Notice you said “back in the day” too!
Now you have to wonder if this younger generation knows to do that? Think about it. Cloth diapers were used generation to generation so mother taught daughter and there was a few grannys helping out too. I’d say by the middle 1970’s cloth diapers fell out of favor due to the ease of pampers. So many women only know the convenience of disposable. Do you see the picture I am trying to paint here? Add that with the public school’s idea of education and I am not at all surprised at anything that could happen at a laundry mat.
