Homemade Laundry Soap – Fels Naptha Soap

Tired of not having clean clothes, running out of detergent or spending too much on ever increasing costs to do laundry?   This is the recipe for making laundry soap.  It doesn’t sud but that’s okay because that’s not what cleans our clothes anyway.  I think that was just a marketing gimmick to make us feel like the detergent was really doing something.  Using the remainder of the bar as a spot cleaner works really well, too.   Happy clothes, happy family, happy laundry day or days and days as in my case.

Grate the Fels Naptha Soap and place in a sauce pan.  Add six cups tap water.  Heat until the soap melts.  Add Washing Soda and Borax stirring until dissolved.  Remove from heat.   Pour four cups hot water into the jar or bucket.  Add soap mixture and stir.  Add one gallon plus six cups of tap water and stir.  Let the soap sit for twenty-four hours to gel.  Use 1/2 cup per load.  Stir each laundry day.   This soap is not sudsy, but rest assured,  will clean your clothes.
