How to make laundry detergent

This week, I did something that has been on my To-Do List for a few years. Today I learned how to make laundry detergent! I’ve put off doing it because I didn’t believe I was going to save enough money to warrant the effort and therefore did not have a fire under me to get started. However, over the past year, I have fought with the laundry and struggled to get it to turn out as I want it to. It just never smelled as fresh as I’d like.

So, I researched. I found out that a few years ago, a key ingredient to cleaning clothes was removed from detergents. My sister-in-law has been making her own laundry detergent for a while and I asked her what ingredients she used.

She listed: Fels Naptha, Arm & Hammer Washing Soda and Borax Powder. I took a bit of Borax and added it to my current laundry detergent. It made such an amazing difference that I decided it was time to go ahead and make my own laundry detergent.

You will also need:


  1. Grate the Fels Naptha soap and place the shavings into the cooking pot. Add 12 cups of water. Heat and stir until the soap melts. I suggest a medium heat at most.
  2. Add the 1 cup of Arm & Hammer Washing Soda and the 1cup of Borax Powder. Stir until they dissolve. Remove from heat.
  3. Pour 1 gallon of hot water into the bucket. Add your soap mixture and stir.
  4. Add 3 gallons of water and stir. (I actually add just a bit less than this.)
  5. Let the soap sit for a while before use.
  6. Use ½ cup per load.

TIP: I sometimes add a splash of vinegar when I wash towels, sheets, or really soiled clothing.
