Notes:
  • When melting the soap, DO NOT let it boil. It will suds over and you may have a super clean stove-top, but a huge mess to clean up!
  • It does take a bit for the powders to dissolve – so be patient. If you don’t blend the final product, sometimes there’s a top layer due to separation.
  • Stir well or shake the jar before measuring out for a load of laundry.
I chose to share this recipe because it is a old-fashioned formula used from generations past. It simple, quick and gets the job done. Please read the following information below to understand more about this laundry soap and its differences from the modern day detergent.
  • This recipe makes laundry soap, not a modern synthetic detergent.
  • If you don’t blend it once it has cooked, separation is normal. The soap may form a solid layer on top or become gel-like as it cools. Simply stir or shake before each use.
  • Hard water may cause additional separation or leave soap residue on clothing.
  • This recipe may not perform as well in HE (high-efficiency) washing machines or for heavily soiled loads.
  • Store at room temperature. If it becomes too thick, warm gently and stir.
  • Since this recipe contains Fels-Naptha, it is best described as low-tox rather than no-tox because the soap contains fragrance and other manufactured ingredients.
  • You can also use an olive-oil based castile soap bar or coconut oil soap bar.
