Homemade Laundry Detergent – Dry


What you’ll need:


1 bar pure soap (Kirk’s, Fels-Naptha, castile, orhomemade bar soap)

1c. Washing soda(don’t confuse this with baking soda - not the same!)

1/2 c. Borax

Medium size container with lid

Dry measuring scoop

Here’s what you do:



  1. Grate your bar of soap as fine as you can. The finer the grate, the better results you’ll have in the soap dissolving.
  2. Place the grated soap in your container.  
  3. Add Washing Soda and Borax to the grated soap in your container.
  4. Mix well.  Cover and store till you’re ready to use.
  5. Use 1 T for a regular load, or 2T is heavily soiled.  You may need to adjust slightly, depending on the hardness of your water.


Fels-naptha works great on heavily soiled clothes.  I’ve been known to have 2 tubs of detergent going at the same time, one of Fels-naptha and one of regular soap.  


Essential oils, if desired, can be added at the time you mix your detergent or with each washer load.


Washing soda, borax, Kirks, and Fels-naptha are usually found with similar laundry products.  Dr Bronner’s can be found with bath soaps (and some are scented, if you like that!)  Sometimes, they are often found with general cleaners.


Washing soda is a water conditioner/softener, detergent booster, and deodorizer.  

Borax helps lift stains and remove/control odors
