We started making our own laundry soap about 2 years ago and haven’t looked back. It’s super easy, minus the whole hand-cramping, grating-a-bar-of-soap thing, but once it’s done you don’t need to make another batch for a while. I just bought a cheap-o cheese grater from the dollar store and only use it for this purpose. We use about a tablespoon per load and it lasts us about six months.
Homemade Laundry Detergent
- 1 bar of Fels-Naptha laundry soap, shaved
- 1 cup of borax
- 1 cup of washing soda
Thoroughly stir together for 5 minutes. Each batch yields 32 ounces which equals about 64 loads based on how many tablespoons you use per load. That’s it!
