I made laundry soap today. I got my recipe from diynatural.com. I doubled it because I do A LOT of laundry. It took 10 minutes to mix up. I won't go in to great detail why I'm making my own. The short answer: 1. cheaper 2. better for environment, i.e. phosphate free 3. less waste 4. take that, Tide.
2 cups borax
2 cups washing soda (not to be confused with baking soda)
2 bars ivory soap, shredded
