How to make the best DIY homemade laundry detergent. This recipe is non-toxic, fights stains better than commercial detergent, and cheap! I’ve been making this liquid laundry detergent for years (originally shared in 2014!) because of its amazing cleaning power.
What Readers Say
“Perfect recipe! Just tested it today, and my laundry smells wonderful and cleans very well! Will use this recipe instead of constantly going to store just to buy a new bottle of detergent every time I run out of it.”

10 years ago, I started making the switch to natural cleaning products, including laundry detergent!
I’ll never forget the look on my family’s face when I proudly announced my new venture: homemade laundry soap. “You made what?“
At that time, the majority of recipes online called for a bar of fels naptha, washing soda, and Borax. The first time I made this original recipe, our clothes came out with chalky white spots.
The second time, I made a simple swap: liquid Dr. Bronner’s castile soap instead of the fels naptha soap bar. This time, the detergent worked just as good as Tide.
I set out to make a homemade liquid detergent that was effective at fighting stains and odors, and didn’t ruin our clothes. Success!
Why Make Your Own Homemade Laundry Detergent
Ingredients Needed
This recipe, made with simple ingredients, makes 1 gallon of homemade soap.
- 1 cup borax (freshens, deodorizes, and lifts dirt and stains)
- 1 cup washing soda (freshens and deodorizes)
- 1 cup liquid castile soap or Sal Suds (the main cleaning agent, lifts dirt and cleans)
- 50 drops essential oil (optional for a scent)
- 15 cups water (distilled water, found in any grocery store, is best as it doesn’t contain containments found in tap or filtered water)
Equipment Needed
- Large saucepan or Dutch oven (enough to hold 1 gallon of liquid, 15 cups)
- Storage Jars (such as 2 half gallon-size glass mason jars, 1 gallon-size jar, or reuse an old detergent bottle)
How to Make DIY Laundry Detergent
Thicker Detergent Tip: This recipe calls for 15 cups of water. If you’d like a thicker, more concentrated soap, use 10-12 cups of water.
Step 1: Boil 6 Cups of Water
In a large saucepan or Dutch oven, bring 6 cups of water to a slight boil. Once the water begins to boil, turn off the burner.
Step 2: Add All Remaining Ingredients
Add the Borax and washing soda. Stir to dissolve. Then add 9 cups of room-temperature water and 1 cup of liquid castile soap. Give the ingredients a stir to combine.
Step 3: Allow to Cool for 5-10 Minutes
Allow the soap to cool for a few minutes before pouring into one large gallon-size jar or smaller containers, like quart-size jars. Make sure your jar(s) are heat-safe. If not, wait until the soap is cool, then spoon the soap into the jar(s).
If you’re reusing an old detergent bottle, make sure the soap is fully cool before adding to a plastic container.
Step 4: Add an Essential Oil For Scent
Add an essential oil of choice (if using) to the soap (now in the jar) and stir to combine with the detergent.
The essential oil will add a subtle fragrance, but shouldn’t be added until the soap cools as heat will cause the essential oil to evaporate.
How to Use This Liquid Soap
The detergent is ready to use immeadiately after making. And may be stored for later use.
- Give the jar a good shake or stir (with a long spoon) before use.
- Use this detergent just as you would any laundry soap to clean clothes.
- This homemade liquid laundry soap is highly concentrated which means you need only a small amount to get a dirty job done.
- For top loading washer machines, use 1/8-1/4 cup.
- For a front loader, use 1-2 tablespoons.
- Add the detergent directly to your washer or the laundry soap compartment.
With the leftover castile soap, make over 24 different household products, from all-purpose cleaner to stain remover to homemade face wash!

Homemade Liquid Laundry Detergent

Ingredients
- 1 cup borax
- 1 cup washing soda
- 1 cup liquid castile soap unscented or scented

it coagulated after 24 hours making it almost impossible to pour, stir or use; wish i made a smaller batch. I live in a humid area so i need a liquid laundry soap and not a dry one that will clump. This recipe did not work for me.
Hey cassandra a lindenberg, I also live in a humid climate and haven’t had any issues with using a clumpy soap. The clumpking described is also discussed in the article -this is something that occurs. You can still use the soap in this form, no need to toss, just scoop and add.
Hi, goog day. I have made your recipe and am using it to wash my clothes, but there is NO foam present. Is the normal? I am a man that does the washing at home and i do not want to look like a paw paw. If my wife sees there is no foam she might thinks there is something wrong. I am going to try making the softner. These things are getting more expensive every week.
Thanks and kind regards.
Deon.
Hey Deon, Yes, foam isn’t needed to clean clothes. There won’t be any foam in this recipe.
Can I substitute the borax for additional washing soda? or is it better to use both?
Hey Sam, It’s best to use both, they both play different roles. But you could certainly try using all borax.
Hey Kristin!
I tried this today. It’s been sitting for about 4 hours now and it has NOT gelled up. Does it typically take longer than that? Can I still use it if it doesn’t gel or does that suggest that I messed up?
Someone else made some for me that gelled up. This is the first time I’m making it myself and it doesn’t look the same. That’s why I’m asking.
Thanks so much!
Hey Alex, It may take days to gel. Gelling doesn’t mean it’s ready or effective; it’s just a chemical reaction/result. It’s ready to use, in liquid or gel form.
can you use this soap recipe in a HE high-efficiency washing machine.
Hey Marjie, Yes
Can use citric acid instead of borax ?
Hey Lindsey, I haven’t tried, so I can’t speak to using citric acid.
can I leave out the borax?
Hey Jessica, You can try and see how you like it.
I tried this recipe, the soap was clear and liquid at first and slowly got clumpy. Now sometimes the clumps get stuck in the soap compartment, what should I do? How do I thin it out again?
Hey Shelby, Yes, it will gel/clump up. If it’s getting stuck in the soap compartment, I would add directly to the wash.
Where can you buy washing soda? I’ve never heard of this thank you.
Hey Darlene, In the US, it will be sold in most grocery stores, Target, Walmart, and Amazon. Outside the US, I believe it’s called Sodium carbonate.
Can I use bottled spring water to instead of distilled water in any of your laundry recipe?
Hey Michelle, Distilled is always the safest option.
This is going to be my first time testing out making my own laundry detergent. This may sound silly, but the washer pours water into the load and I wa surprised by how much goes into making liquid detergent too. Could I opt for adding some vinegar instead of all water to this recipe? I typically add a splash of vinegar to my loads with store bought detergent (been using 9 Elements) and it seems to work very well. Thanks!
Hey Alexandra, I would not use vinegar. Vinegar and castile soap don’t mix and will create an oily mess. You can add some vinegar for a laundry softener, during the washing cycle, but don’t directly mix the soap and vinegar in the same solution. Here’s more info about the two ingredients: https://livesimply.me/4-natural-cleaning-ingredients-to-avoid-combining/
Is it okay to add baking soda?
Hey Jo Ann, Baking soda will not work. It’s different chemically speaking than washing soda.
Can I use scented castillete soap, like peppermint Dr Bronner’s, and omit the essential oils, or will that scent evaporate too?
Hey Sarah, Any scent is going to be subtle, whether from Dr. Bronner’s or essential oils. You can definitely use scented castile soap instead of essential oils.
Can this be used in HE washers?
Hey Kylie, Yes, I’ve used this with HE washers.
You say to use within 1 month. Will this soap go bad, if I don’t use it within 1 month?
From a safety standpoint, it’s best to use anything with water (and no preservative) quickly. That’s why I recommend a short storage. You can reduce the amount if you think you won’t use all of it within that time period.
Mine got sudsy on top of the jug and gelled up and got quite clumpy in the rest. Still safe to use? Should I add more water?
Yes, completely normal.
Hello! My laundry soap is clearer than the yellow soap shown in the picture. Is that normal or did i not use enough of an ingredient?
Thank you!
Yes, that’s normal. It will depend on the type of castile soap used. Some are more yellow in nature.
