Making your own detergent is a great way to save money on doing your laundry. You get a lot more bang for your buck! I started with the powdered detergent and just got brave enough last weekend to try the liquid. It was a LOT easier than I thought. Powdered detergent 1 cup Borax 1 cup Washing soda 1 bar of soap (I prefer Fels Naptha which is a laundry soap.) Grate the bar of soap.
