I dont really know where to post this so I decided here coz I need help.. Hi, i'm doing my investigative project at school. I have read that the Ancient Romans used urine to clean their clothes so I came up with this idea; to make a laundry detergent with urine as a main component. My problem is how would I make one? I prefer having powdered detergent but liquid detergent might work too. But my problem is what would I mix with the urine to make a detergent..? That's all.. Thank you for those who would help.
