Yeah, I was thinking more about the grandparent above that said it took 45 minutes and that had to mean breakdown/cleaning/reassembly in one step. I was there in 1985-86 and we did like you said, one crew member did the cleaning at close and let it air dry for the morning crew. But that was also because shakes/ice cream wasn't served during the breakfast shift. Someone had time in the morning to assemble and prime the machine before 10:30am (me). I'm guessing 24/7 operation changed when and how the cleaning was done, leading to more contamination instead of less.
