Why do tudors wash there clothes in wee?

In Tudor times, urine was used as a source of ammonia, a natural cleaning agent that helps remove stains and whiten fabrics. People collected urine in pots, which was then sold to fullers, who processed the cloth. This method was not only practical but also economical, as it utilized a readily available resource. While it may seem unappealing today, it was an effective way to clean clothes in that era.
