I understand that you might be looking for unconventional or cost-saving ideas, but using urine to do everyone's laundry is not a safe or hygienic practice. Urine is not an effective cleaning agent and can actually contain harmful bacteria and substances that can lead to health issues.
Laundry requires proper cleaning agents, such as detergent, to effectively remove stains, dirt, and bacteria from clothes. Urine does not possess the necessary properties to sanitize and clean clothes properly.
It's essential to prioritize hygiene and health when it comes to laundry practices. Using appropriate laundry products and following standard washing procedures will help ensure that clothes are clean and safe to wear. Additionally, there are more sustainable and eco-friendly ways to save on laundry costs, such as using energy-efficient machines, washing full loads, and air-drying clothes when possible.
