In the really olden days, people used to collect urine, let it set around a while, then wash their clothes in it. The ammonia in the urine was what made your whites whiter. I wonder how many times they rinsed their clothes back then. Maybe they all smelled of pi$$.

According to our guide, the laundry service would accept just about any kind of urine, but supposedly zebra and giraffe urine were greatly coveted. After washing laundry in urine and rinsing, the laundry would be “smoked” to help get rid of the ammonia/urine smell.
