Recipe for Homemade Laundry Detergent

Sharing is caring!

I have been making homemade laundry detergent powder for almost two years. I absolutely love it.

I have made a couple of different versions. All of them are really easy, they each just smell a bit different.

This recipe for homemade laundry detergent uses Fel-Naptha and Gain Scent Booster. You will be able to do 271 loads of laundry with it and it only cost $0.10 per load of laundry!

Let me who you how easy this is to make!

Recipe for Homemade Laundry Detergent using Fels Naptha Soap

Here is what you will need.


Run the Fels-Naptha bars through the food processor using the shredding blade.

Put all of the shredded Fels-Naptha in a large bowl.

Change the blade to the chopping blade.

Put 1/4th of the shredded Fels-Naptha back into the processor. Add in 1/4th of the baking soda.

Chop on high for 30 seconds or until well blended.

Dump the combination into a large bucket. I use a Home Depot 5 gallon bucket. You can read more about these details in the first DIY detergent post I did.

You’re also going to add all of the other ingredients to the bucket. You can read more of the step-by-step directions for homemade laundry detergent for more details.

I really love the smell of this Gain Scent Booster. I’ve used Purex Crystal’s, Bounty Scent Boost and Downy Unstoppables in the past as well. All of them add a unique and lovely smell. If you have a family member with sensitive skin, you can omit this.

Put a lid on the bucket and roll it and shake it until it is well mixed.

I also like to use a metal slotted spoon or spatula to do some mixing by hand as well. You want it well combined.

Then, fill a large glass jar with detergent. Ensure it has an air tight lid.

Use one coffee scoop of detergent for each load. (2 T)
