Virtual Sefer Laundry Soap shared by Amy

Fels Naptha soap, grated (enough bars to make 14 ounces)
4 cups washing soda
2 cups borax
Instructions: Mix all ingredients together and store in a lidded container. This will last a LONG time!
For light loads, use 1 tablespoon. For heavy or heavily soiled loads, use 2 tablespoons.

I shredded the Nels Naptha bars with the cheese grater in my food processor and then chopped it up finely with the regular blade. I then mixed it with the other ingredients.
