How To Make Laundry Detergent Powder

As you are aware, I make my household and personal products.  Laundry detergent is another product I make.  I found my first recipes years ago; they were long and complicated.  The internet age has advanced the process to almost nothing.  There are hundreds, if not thousands, of sites with laundry powder recipes.  This is the one I use.  Not only is it a good detergent, it is very inexpensive to produce.




  • 1 bar of Fels-Naptha or Dr. Bronner’s Castile Bar Soap(I have used both but like Dr. Bronner’s best)
  • 1 cup of washing soda (this is not baking soda)
  • 1 cup of Borax (add if you use hot water wash)

Grate the bar of soap (photo of soap to the right) then place in a food processor or blender and process to finest  particles possible.  Finer particles dissolve well.  Place in a container, add washing soda. mix well.  Use as you would any powder detergent in the cold water wash. Please label the contain as children are inquisitive.


If you use hot water you can add a cup of Borax to your mixture for added boost of cleaning.  Borax will not activate in cold water.  You could add a cup of borax dissolved in a pint hot water to the cold water wash if you desire.  I find I can’t remember to go back and add the borax.


FINISHED, YOU ARE AT THE END OF THE PRODUCTION PROCESS:  Wasn’t that easy!  That’s it ladies and gentlemen.  A good detergent that cleans well and is very cheap.


NOTE:  Fels-Naptha, washing soda, and borax are available at Wal-Mart or on-line.  If you like the recipe and want to make larger quantities, washing soda and borax is available on-line in large containers.

Dr. Bronner’s Castile Soap is available on-line.  Dr. Bronner’s products are wonderful and clean very well.  If you have not used Dr. Bronner product line,  I would suggest you give them a try.  I have posted a recipe for foaming hand-wash using Dr. Bronner’s liquid castile soap.
