Human urine is full of ammonia and other chemicals that are great natural detergents. If you worked in a Roman laundromat, your job was to stomp on clothes all day long—barefoot and ankle deep in colossal vats of human pee.
It gets worse, the ancient Romans also used urine as a mouthwash to whiten their teeth.
- ravar 7y agowait, our urine doesn't contain ammonia, we convert nitrogen to urea as it is far less toxic than ammonia.

In pre-industrial times urine was used – in the form of lant or aged urine – as a cleaning fluid.[25] Urine was also used for whitening teeth in Ancient Rome. https://en.wikipedia.org/wiki/Urine#Cleaning https://en.wikipedia.org/wiki/Urine#Cleaning
