I’m sharing my easy homemade laundry soap recipe with you.Jump to Printable Recipe
It’s been 8 years of using this homemade laundry soap, and I think that it’s time I share it!
Our family loves it!
Not only because it’s easy to make but because it’s an amazing laundry soap that cleans everything we throw in the washing machine.
My son has made it so many times I wouldn’t be surprised if he continues this practice when he lives on his own someday.
It’s that easy.
What I love about this recipe is it doesn’t include borax.
Or any harsh chemicals.
It only takes 4 ingredients.
A possible 5th ingredient is adding essential oil to the laundry soap at the end when mixing this batch.
My favorite essential oil is bergamot.
It has a relaxing and rejuvenating scent that I love so much!
But you could add any essential oil you love.
Or nothing at all.
Here are the ingredients.
This is for ONE batch.
- 5 lbs Baking soda (Walmart for under $4)
My husband buys a big bag from Costco then we weigh 5 lbs. on a food scale.
- 55 oz. Arm & Hammer Washing Soda (Walmart $4.17)
- 3 lbs (BABY) Oxy Clean stain remover OR any Oxy Clean stain remover (Walmart $7.96)
Any Oxy Clean stain remover will work.
This BABY pink tub can be found here.
I have it on reoccurring order through Amazon since it has been hard to find lately.
This stuff works amazingly to keep my whites white and colors bright.
- 4 bars of Kirks Unscented Castile Bar Soap (Vitacost $4.88)
The keyword, Fragrance-Free, is what you want to look for.
I love using these bars of soap when possible.
Lately, the fragrance-free bars are out of stock.
So, here is a photo of other bars that are Kirk’s brand but have a different look.
$21.01 TOTAL COST (Priced in January 2022)
Equipment you will need:
- Huge bucket like this one.
Or my favorite one to use is these ones.
- Food Processor with a cheese grater. This is the exact one I have here. But any will do.
- Long-handled wood spoon like this one. Or for a metal one, like this one.
Instructions on how to make this super easy laundry soap in 7 steps:
Step One: Open up the bag of baking powder, a box of Arm & Hammer washing soda, and a tub of Oxy Clean and pour them into the bucket.
Step Two: Open up all the bars of soap.
Now for Step Three: Place the cheese grater attachment onto your food processor.
Step Four: Take one bar at a time and grate each bar by pushing it down into the slot of the food processor.
Step Five: Empty grated soap into a bucket.
You may have to empty the grated soap from the food processor bowl after each bar of soap.
It depends on how big your food processor is.
Step Six: Stir all the ingredients together.
Once you’re done grating the bars of Kirk’s Fragrance-Free Castile soap, you will need to stir all the ingredients together.
Use a spoon, if you like, to stir.
But from my experience, it is best to use your hands.
Taking your hand or spoon, go down to the bottom and pull up.
This will take a good 3 minutes of constant stirring.
Step Seven: After you are done, add 50 drops of essential oil to give it a personalized smell. (Photo of the bergamot is a link.)
I love to use Bergamot essential oil.
It has a scent that the men in my life love, too.
How to use detergent when washing clothes:
Put the required amount of homemade laundry soap into the washing machine drum before putting in your clothes.
This helps to keep detergent from clumping in the soap dispenser.
Laundry soap can be added to the laundry machine barrel of both the top and front loaders.
The measurements are as follows:
Small load – 1/4 cup
Medium load – 1/2 cup
Large load – 3/4 cup
Extra large – 1 cup
Things to know about the laundry soap.
One batch of this homemade laundry soap can last up to 2 months.
Depending on the size of your family.
There are no chemicals or bad ingredients in this recipe.
So, it is safe for those who have allergies and are sensitive to harsh chemicals.
You can tweak this recipe to fit your needs by adding your scent if you like.
You can make it smell like lavender or lemon by adding 50 drops of essential oil or find castile soap like Dr. Bronner’s bar soap with a lavender scent, for example. Link here for the bar soap.
It is a versatile recipe that can work for you.
Using wool dryer balls and essential oil for a fresh scent.
I love my homemade laundry soap as is.
How I get that wonderful scent into my clothes is by using essential oil & those wool dryer balls here. (Photo is a link.)
I love to put 5 drops onto each ball (I use 3 wool balls in my dryer per drying time).
As mentioned in this post, I use Bergamot essential oil.
But here is a wonderful set of essential oils from Woolzies, here.
I’m recommending these cause of the price.
But there are so many options out there; this is just an idea.

Why do I make this homemade laundry soap for my family and I?
This has been such an easy alternative to the expensive and chemical-laden laundry detergents out there.
My daughter had an allergic reaction to many of the name-brand laundry detergents.
I went on a hunt for an alternative.
In my search, I found some that were all-natural but cost way more than I wanted to spend.
It was apparent that making laundry soap was my best option.
So, I found an easy one and stuck with it.
I know what is in it.
It’s easy to make and costs way less than premade ones.
Plus, it lasts a long time.
There was no looking back.
We love making our own detergent. It’s empowering!
Plus, there are other things we can add if we like, that can make it even more amazing.
Like the Dr. Bronner bars of soap.
The one I’m recommending is the baby unscented ones.
But if you want to add a nice fragrance, Dr. Bronner’s bars of soaps come in many pleasant scents.
You can find these bars of soap at most grocery stores or big box stores like Target, Fred Meyer, etc. (Photo is a link.)
Kirk’s soaps are getting harder to find, and the prices are going up lately.
Especially the unscented ones.
I linked a Vitacost link above (top of post) for Kirk’s bar soap that is cheap but not unscented.
Just for your convenience.
So, Dr. Bronner’s soap, here, is another option to add instead of Kirk’s soap.
Any Castile bar soap would work.
