Homemade Clothes Soap Recipe Using Fels Naptha, Washing Soda and Borax

Homemade Laundry Soap

Last week my boss brought me the recipe that her daughter is using. I looked around the ‘net for the recipe, just to see if there were any other variations and I found plenty. I found that Trent over at The Simple Dollar makes his own laundry detergent and provided a tutorial here. The recipe he uses is the same as the one my boss brought in, but he uses his solution full strength, one cup per load. The recipe my boss brought says to pour the full strength solution into an old laundry detergent bottle – but only fill it halfway, then fill the rest of the way with water. Also, this recipe says to use 5/8ths of a cup.

The recipe is the same as Trent’s:

4 cups hot tap water
1 Fels-Naptha Laundry Bar SoapFels-Naptha Laundry Bar Soap
1 cup Arm & Hammer Super Washing Soda
1/2 cup 20 Mule Team Borax Laundry Pretreater

Grate bar of soap and add to saucepan with water. Stir continually over medium-low heat until soap dissolves and is melted.

Fill 5 gallon bucket half full of hot tap water. Add melted soap, washing soda and Borax. Stir well until all powder is dissolved. Fill bucket to top with more hot water. Stir, cover and let sit overnight to thicken.

Stir and fill a used, clean, laundry soap dispenser half full of soap and then fill rest of way with water. Shake before each use, as product will gel.

Optional: You can add 10-15 drops of essential oil per 2 gallons. Add once soap has cooled. Lavendar, tea tree oil or rosemary are suggested.

Yield: Liquid soap recipe makes 10 gallons.

Top load machine 5/8 cup per load ~180 loads
Front load machine 1/4 cup load ~640 loads

I will probably make a batch up on the weekend. It is definitely going to save money over the cost of buying commercial detergent. UPDATE: I did make the soap and it was successful!  Click here to read the post.

  1. I would love to know how this turns out because I have wanted to try it but haven’t. Are you going to add a bluing agent so that the whites don’t get dingy? I’ve heard they carry it at Winco.


  2. Hi there Mrs. A I would love to try the homemade method for laundry but I can’t my youngest son is allergic to the ingredients, so I have to buy a natural 1. If you like that you should try making your own dishwasher detergent I have posted about it on a blog of mine if you or any other would like this recipe please email me. The dishwasher one works I have had some people say that with really hard water its not as effective, but I haven’t had that much of a problem with it. Good Luck and I hope the garden is doing well.
