Step 1: Materials

Measuring instructions: A regular-size load of laundry will require slightly less than a ½ cup but a large load of laundry will require a full ½ cup


  • 4lb Box of Arm & Hammer Super Washing Soda
  • 4lb Box of Arm And Hammer Baking Soda
  • 4lb Box of 20 Mule Team Borax
  • Oxi Clean (3lb container)
  • 4 Fels Naptha Laundry Soap
  • 2 Downy UnStopables
  • Garbage bag
  • Cheese grater
  • 2 gallon container to store your soap
  • ½ cup measuring scoop (Or use one from Oxi Clean container)

Step 2:

Pour Arm & Hammer Super Washing Soda, Arm & Hammer Baking Soda, 20 Mule Team Borax, Oxi Clean and both containers of Downy UnStopables into the empty garbage bag. This will take about 5 minutes.

TIP: Some ingredients come out of the box in clumps, be sure to break these up before proceeding to next step.

Step 3:

Using the cheese grater, grate the Fels Naptha Laundry Soap into a separate container until all 4 bars are grated into fine slivers. This step will take the longest, so be sure to set aside about 15 minutes to fully grate each bar of soap.

Step 4:

Empty the finely grated Fels Naptha Laundry Soap into the garbage bag with the previous ingredients.

Step 5:

Twist the top of the garbage bag to keep all the ingredients in the bag.

Step 6:

Gently move the garbage bag around to mix all the ingredients. This should take 1-2 minutes.

TIP: Sitting on the ground may be the best way to approach this.

Step 7:

After mixing the ingredients, carefully transfer the mixture into the container that you chose to store your soap in.

Step 8:

Place measuring scoop inside storage container for future use. The scoop from your Oxi Clean can be used as your measuring cup.

I've heard that homemade liquid detergent goes bad after so long and I'm wondering, will this also go bad? Or will it stay for a longer time since it's powder?

Great instructable! I love making my own laundry detergent. I just us normal soap for mine and I add essential oils to get the scent I want.

I made my own with borax the first time and then decided to look into the things I was using now that I knew exactly what was in my detergent. Borax is actually a really nasty substance and in powder form can cause respiratory issues. Build up of borax in ground water has also been linked to some ecological issues. I omitted it from the next batch of detergent and taking it out made no difference in the cleanliness of my clothes.


making my own laundry soap is fun and your clothes smell great don't for get you can use any hair conditioner of your choice and vinegar mix the 2 and use it for the rinse.awesome stuff.

My partner and I tend to get our clothes pretty grungy when working out of our workshop, will this recipe get out those hard and sometimes greasy stains? I'd love to be able to make my own laundry soap. Thanks!

Hello ! Yes, this laundry recipe is great for getting stains out. The Oxi Clean and Baking Soda really get the job done!

I've been making my own soap now for years, never thought of adding downy... hmmm...

To speed the process I stick each bar of Fels Naphtha in the microwave, medium power, for about 3 min. They get all puffed up, and once they cool the go into the food processor until finely powdered. Be aware, though, your house will smell very strongly of soap for several days to come.

This is the same exact recipe I use. I found a old food processor at a yard sale that I use to grate the soap. Makes things go a bit faster and is easier on the arthrits in my hands,
