Roman Empire | Random Fact / – Funny.
The Romans used urine as a cleaning agent. They believed that the ammonia in urine had cleaning properties, so they would use it to clean their clothes and even their teeth. They would collect urine from public urinals and use it for various cleaning purposes. This practice might sound strange to us today, but it was a common part of Roman hygiene and household maintenance.
The Roman Empire was famous for roads, aqueducts, and grand architecture, but it also had some hygiene habits that sound downright bizarre today. One of the strangest? Using urine as a cleaning product.
Romans believed urine was valuable because it contains ammonia, a natural cleaning agent. Public urinals were set up across cities, and the collected urine was sold to fullers (laundry workers) who used it to wash and whiten clothes. Yes, Roman laundry involved trampling garments in vats of old pee.
It didn’t stop at clothing. Some Romans even used diluted urine as a mouth rinse, believing it helped clean teeth. While that idea makes modern stomachs turn, the science behind it wasn’t entirely wrong, ammonia does break down stains and grease.
So while we remember Rome for marble statues and mighty emperors, everyday Roman life reminds us that history is often messier, and funnier, than textbooks suggest.
The Roman Empire used urine extensively from at least the 1st century BCE through the 5th century CE, primarily for industrial and domestic purposes such as tanning leather, whitening cloth, cleaning textiles, and even oral hygiene. The practice was so widespread that Emperor Nero introduced a tax on urine collection, known as vectigal urinae, in the early 1st century CE, and Emperor Vespasian later reinstated it around 70 CE to replenish the empire’s treasury. Urine was valued for its ammonia content, which acted as a natural cleaner and bleaching agent.
The Roman Empire notably re-imposed the urine tax around 70 CE under Emperor Vespasian to replenish the imperial treasury after the civil war. While Emperor Nero had introduced the vectigal urinae earlier in the 1st century CE, it was Vespasian who reinstated it around 70 CE, making it a well-documented and widespread practice. Some sources mention 74 CE as a possible date, but 70 CE is the most consistently cited year.
