Roman Laundry Ran on Human Urine
In ancient Rome, laundry workers scrubbed clothes in vats of stale human urine—collected from public toilets.

Urine: The Ancient Roman Stain Remover
Roman laundry businesses collected human urine from public urinals and household pots. Clothes were soaked, stomped, and scrubbed in it by professional cleaners called fullers. The smell must have been overwhelming, but the results spoke for themselves—whiter togas, softer linens.
A Tax on Pee
The Emperor Vespasian saw profit where others saw waste. He taxed the collection of urine, and the fees filled Rome’s treasury. The slang term for public urinals—'vespasiani'—still echoes his legacy in Italian today.
Urine contains ammonia, a natural cleaning agent, so Roman fullers (professional launderers) prized it as detergent. The Emperor Vespasian even taxed the urine-collection business. Step into the back alleys near the Tiber and you’d see clay pots brimming with yellow liquid, ready to be dumped onto sweat-soaked togas. This was big business, and the stench was legendary.
