Optional Essential Oils for Mold Prevention


  • Grate the castile soap with a grater.
  • Put the grated castile soap pieces in a food processor bowl. Pulse until only large crumbs (no chunks) remain.
  • Add baking soda to the food processor and pulse until ingredients are in powder form and combined (about 1 minute).
  • Add washing soda to the food processor and repeat pulsing until combined well.
  • Dump the mixture into a storage container and add borax and OxiClean. Combine well with a spoon.
  • Add the essential oils, if using, (optional) and mix well.
  • Store detergent in an air-tight container to help avoid clumping.
  • Simply add about 2 tablespoons directly into your washer bin with your clothes (you might want to only use 1 tablespoon for HE front loaders. Add more, if desired, for larger or more heavily stained loads.


You can also simply chop up the castile soap bar instead of grating it, but grating will help the food processor work better without the concern of damaging the blades.
If you live in a humid climate, your laundry detergent can have a tendency to clump up. To help avoid that, you might wish to keep a dessicant in with your detergent.
