1 bar laundry soap (like Fels-Naptha)
1/2 cup washing soda (not washing powder, not baking soda)
1/4 cup Borax
Grate bar of soap and melt in 4 cups of water over medium heat, stirring until completely melted. Stir in Borax and washing soda into hot water in 5 gallon bucket. Add melted soap and stir. Fill bucket with hot water and stir. Lid and let gel 24 hours. To use, fill old detergent container half full with detergent, half full with water. Shake to mix prior to using. Use 1/4 cup for front loader washing machine. Use 5/8 cup for top loader.
I just made this about a month ago and I have a front loader and it seems to be working fine. My friend that gave me this recipe has 5 kids and she does about two loads of laundry a day and this lasts her about 4 months. She, nor I, use this to wash cloth diapers, though. We use something else for diapers.
