DIY Laundry Detergent

DIY Laundry Detergant 

Trying to save a little money? Curious about the ingredients in your laundry detergent? Want to be more eco-friendly? Make your own laundry detergent! Super easy and very cost-effective. 

The cost for a year’s worth of DIY laundry detergent (314.8 ounces) is about $28, or $2.34 a month. For reference, the last time I bought branded laundry detergent was in October of 2021. I paid about $19.39 for 1 box that was 143oz; which only lasted about 3 months (or $6.46 a month). 

When I add it up, it is about $50 a year that you are saving by making your own, (please note, you can save even more if you buy your products in bulk, I bought all of my cleaning supplies from either Target or Amazon). I honestly feel like my detergent cleans my clothes better and leaves them softer! 

So if I have spiked your interest, let’s get started! 


  • 32 oz Borax
  • 32 oz Arm and Hammer Baking Soda 
  • 27.5 oz  Arm and Hammer Laundry Boost 
  • 1.5 bars of Fels-Naptha Laundry Bar
  • 28 oz Oxi Clean


  • Woodend spoon (only used for laundry detergent)
  • Grater (electric or manual) – I use an old food processor that I just use for making my laundry detergent
  • 5-gallon bucket
  • Canister to hold your mixture (only used for laundry detergent)
  • Tablespoon measuring spoon (only used for laundry detergent)


  1. Line your 5-gallon bucket with a clean garbage bag
  2. Cut up your Fels-Naptha bar into smaller chunks, and place in your food processor on grate mode or begin to manually grate
  3. Measure and pour all of your ingredients into your bucket, and mix well 
  4. Take the garbage bag out of your bucket, cut a corner of your bag (like you are going to pipe frosting on a cake), and then pour the mixture into your canister
  5. 2 TBS into a large load of laundry is all you need
  6. Enjoy!

Please note, all the supplies I use to make my laundry detergent I ONLY use for my laundry detergent, I cross-utilize these items.
