This is the recipe I use, the liquid just didn't work.--and left my clothes smelling sour. For some reason, zote (tallow) doesn't do this. Plus, the smell is great.- citronella essential oil! I also buy a 13 lb bag of baking soda at Costco (on armour) and bake it at 350 for 45 minutes to turn it to washing soda!
This DIY laundry soap produced more soap than the other recipe I have, but it comes out of solution easily. You'll need to shake it up before using. Also used Dr. Bronner's instead of Fels Naptha to make it green.
