Powdered Laundry Detergent

Here is a different recipe that I found for in-expensive laundry detergent. The only difference is this is dry and not a liquid.

2 cups Fels naptha soap (finely grated)
1 cup Washing Soda
1 cup Borax

Mix well and store in an airtight plastic container.
Use 2 tablespoons per full load.
