If you are looking for a biodegradable alternative to your regular laundry soap, and also want to reduce your packaging (the use of plastic bottles) and save a little money, you can try out this few steps to produce your own laundry soap!


  • 1-2 cups water (to melt grated soap)
  • 1 bar soap (Fels Naptha), grated
  • 5 gallon bucket
  • 1 cup washing soda (sodium carbonate, NOT baking soda)
  • 4 1/2 gallons HOT tap water


  • 1-3 oz. essential oil (in preferred scent, I usually use lavender or grapefruit)


  • Grate bar soap using a hand-held cheese-grater.
  • Place grated soap in a small saucepan and add enough water to cover it.
  • Heat on low, stirring until soap is dissolved.
  • Fill the 5 gallon bucket with HOT water and add dissolved soap solution; stir to combine.
  • Add 1 cup washing soda and optional essential oil and mix well.
  • Mixture will thicken to gel-like consistency as it cools.
  • May be used immediately. Use 1-2 cups per load.

It’s probably best to add this laundry soap in the drum with the clothes if you have a front loader.

Another recipe to try may be:


  • 2 lb box of soda
  • 3 cups borax
  • 2 cups grated soap
  • 30 drops of essential oil


Stir it all together and use about one fourth of a cup per load. Be sure to add the mix to the water before you add the clothes and to use the smallest size grater you can find for grating the soap.
