How to Make Your Own Laundry Detergent for just $0.06 per load!

How to Make Your Own Laundry Detergent

I’ve finally done it. I’ve made my own laundry detergent. I have wanted to for some time but I finally decided that I would give it a try and guess what? It wasn’t difficult. I am a fan of saving money where you can so you can spend it on what you want to. To me, saving money on laundry detergent by making my own makes it much cheaper than buying it. Even though it’s easy to just buy laundry detergent, why not make my own and save money? Do you want to learn how make your own laundry detergent too? Read along and follow the steps that I did and you can end up with your own laundry detergent in no time.


1 cup Arm & Hammer Washing Soda

1 cup 2o Mule Team Borax

1 bar of Fels Naptha

4 cups hot water

2 quart size mason jars

Directions on how to make your own laundry detergent.

1. Cut Fels Naptha into strips.

2. Put the strips into a food processor and process it. If you don’t have a food processor you can simply grate your full bar of Fels Naptha.

3. In a separate bowl, mix the Borax and washing soda together thoroughly.

4. Pour water in a pot and turn it on high. I mean, really crank it up. When the water starts to boil, add your grated or processed Fels Naptha and start a stirrin’. You will have to stir for about fifteen minutes until it is all incorporated. It will start to look like this. Keep stirring until all lumps are gone and the water is yellowish.

It will start to look like this when it’s fully incorporated.

5. When the Fels Naptha is fully incorporated, it’s time to add the Borax/washing soda mixture. Take the pot off of the heat and add the mixture. It took seven minutes for all of it to be fully incorporated for me. You should keep stirring until it’s all incorporated. It helped me to put the pot back on the heat for about the last 2  minutes to help it all incorporate.

6. Next, it’s time to get out those mason jars. Split the product between the jars equally. Then, fill up the jars with water up to the curve at the top of the jar leaving about 1 1/2 inches of space at the top. I forgot to get a picture of this. Sorry 🙁

7. Turn your jars upside down and wait four hours. You will notice that the contents will separate. That’s okay. It’s supposed to do that.

8. Time to whip it up! You can do this one of two ways depending on what you have to use. If you have a blender, mix up your mixture until it whips up nice and smooth. It looks like softened butter when it’s done. If you don’t have a blender, you can use a hand mixer. It won’t be mixed as well but it will still work. I washed out my mason jars just because I like to have everything neat and clean. It’s not necessary.

9. That’s it! When it’s all whipped up you put it in your jars and you have made your own laundry detergent! You use one tablespoon per load. Just put the laundry detergent in the washing machine with the clothes.

I am using this with my HE washing machine because it does not get sudsy which is why you have to be careful to use only laundry detergent with the HE labeling on them for front loaders. This can also be used in top loader washing machines. Again, you just put the laundry detergent in the machine with the clothes.

Here’s the price breakdown for the materials:

Borax= about $3 per box (I had a coupon for a free box so I am estimating based on the research I did online real quick)

Fels Naptha bar= $0.99

Washing Soda= $3.24

                                 $8.22 for this batch

However, I barely dented the box of Borax (76 oz) and washing soda (55 oz). There should be at least 7-8 more batches that you can make. Plus the laundry detergent you just made supposedly lasts for 128 loads! So if you break it down that’s like $0.06/load! Compare that to any laundry detergent you buy, even with a coupon. Hey, at least give it a try if you haven’t before. You might be surprised at the results.

Thanks for reading this post on how to make your own laundry detergent. Have you ever made your own laundry detergent before? What’s your recipe? I’d love to hear your experience.

    I have always wanted to try and the only concern of mine is one of my kids has sensitive skin and some exzema so I wondered how he would handle it.

      Both my little boy and I have eczema. So far neither of us have had any trouble with it, though. I will update the post if either of us start to have trouble with it.

    I have never ever heard of the Fels Naptha Bar! I read and have tried many of the DIY’s for detergents, dishwashers, etc., so now i’m anxious to find out exactly why I haven’t heard of the bar soap before! Thanks! I love learning new things!
