Ancient recipes for soap have been found in Rome. However, it seems that Romans didn’t exactly understand its hygienic importance. Instead of using soap to wash their clothes, they would mix water and urine to clean their laundry.

Even wilder than that, laundry workers would collect batches of urine by setting large vessels on the streets for anyone to pee into as they please. An interesting tactic for sure, but I think I’ll stick to my tide pods.
