Liquid Laundry Soap Recipe
1 bar Fels-Naptha bar soap
1 cup Arm and Hammer washing soda
1/2 cup Borax
4 cups hot tap water (plus more for later)
- Add 4 cups hot water to a small saucepan. Grate the Fels-Naptha soap and add it to the saucepan. Heat over low heat until the soap is melted. Stir the melted soap and water to mix the solution. (Watch closely and stir frequently so it doesn’t boil over!)
- Fill a 5 gallon bucket half-full with hot water. Add the melted soap, Borax, and Washing Soda. Fill the bucket to the top with more hot tap water. Use a large wooden spoon to stir the mixture. Let sit overnight to thicken.
- Stir, and dispense thickened soap into cleaned laundry soap dispensers (use empty containers from commercial brand laundry detergent): fill each bottle 1/2 way, then top the container off with more water. Shake before each use.
This liquid laundry soap recipe yields 10 gallons. For HE machines, use 1/4 cup per load. For top-loading machines, use 1/2 cup per load.
