11 years ago, I started making the switch to natural cleaning products, including laundry detergent!
At that time, the majority of recipes online called for a bar of fels naptha, washing soda, and Borax. But there was one problem: our clothes came out with chalky white spots.
So I made a simple swap: liquid Dr. Bronner’s castile soap instead of the fels naptha soap bar. With this one change, the detergent worked just as good as Tide.
This recipe is non-toxic, fights stains better than commercial detergent, and is cheap! I’ve been making this liquid laundry detergent for over 11 years (originally created in 2014) because of its extraordinary cleaning power.
Homemade Laundry Detergent Benefits
Before You Get Started: What You’ll Need
Ingredients
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
- 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
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.
How to Make Homemade Laundry Detergent: Recipe Steps
- 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 Borax, Washing Soda, More Water, and Castile Soap: 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 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).
- Step 4 Add 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.
What to Avoid Doing
- Baking Soda – Don’t use baking soda in place of washing soda. Washing soda has a different chemical composition and will not work in this recipe. It is NOT a substitute.
- Dish Soap – Don’t use other dish soaps in place of the castile soap. Dish soap will cause the soap to have too many bubbles in the wash.
- Lack of Suds – Don’t assume that a lack of suds and bubbles means the soap isn’t effective. Suds and bubbles don’t equal clean.
- Plastic Containers – If you’re reusing an old detergent bottle for storage, make sure the laundry detergent is fully cool before adding to a plastic container.
- Heat-Safe Glass – Use a heat-resistant glass jar (if using glass for storage), and also allow the detergent to cool a bit (about 10 minutes) before adding it.
- Essential Oils – 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 Prevent Chunky or Gelled Detergent
After a few days the liquid laundry detergent may clump or gel. This is a completely normal chemical reaction that is usually caused when the outside temperature is cooler. There’s no way to completely prevent this from happening; however, one option is to use more water (2-3 cups more) to make a less concentrated soap.
The laundry soap is 100% usable if it gels up (l actually love this form). Simply scoop the detergent from the container and add to the washer.
Key Takeaway: Whether the laundry detergent gels up or remains liquid, it’s 100% effective and usable in both forms.
How to Use This Liquid Laundry Soap
The detergent is ready to use immediately 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 tiny amount to get a dirty job done.
- For top-loading washer machines, use 1/8-1/4 cup.
- For an HE front loader, use 1-2 tablespoons.
- Add the detergent directly to your washer or the laundry soap compartment.
Can I use this in an HE washer?
I do, so I can only speak to my personal experience. I use 1-2 tablespoons per load. If it’s in gel form, add it straight to the washer on top of the clothes.
Always consult your machine’s user guide before using any laundry detergent to know what your machine can and can’t handle.

FAQs
- Can I use a castile soap bar instead of liquid castile soap? Yes, you can. Use a cheese grater to grate a bar of castile soap into the hot water (along with the borax and washing soda). Stir and continue to boil the ingredients to dissolve fully (takes about 10 minutes). I also use a bar of castile soap to make powder laundry soap.
- Is it normal that it’s more watery than soapy? Yes, this is normal. For a thicker, more concentrated detergent, there are two options: use Sal Suds instead of castile soap OR reduce the water to 10-12 cups for a more concentrated detergent.
- The detergent is chunky (or gelled) after cooling, is that normal? Yes, this is normal. Depending on your home’s temperature, the soap may be more liquid or even chunky (like a gel). Both are normal and usable!
- My laundry soap didn’t gel. What happened? If your environment is cooler, your laundry soap may gel after cooling. Or it may not. This is normal. Both forms are 100% good and usable. A reader recently shared this tip you can try as well, “I also like the the detergent to be more gelatinous and I use my immersion blender for a few seconds after it is cool to whip it. It turns white and jelly.”
- Is borax safe? Borax is a debated ingredient in naturally-minded circles. I personally don’t see any reason to avoid it. This borax article from Wellness Mama has fantastic information.
- Can I use this soap to lift stains? Yes, you can. You can either add the garment to the washer or add the garment to your kitchen sink with the soap and water and soak the garment to lift the stains. Or, apply the soap directly to the stain and scrub. If you’re dealing with tough stain, I recommend using this homemade stain remover before washing the garment.
- Does this soap work with hard water? Yes, it does. I have hard water and this soap works great. You may want to use this laundry softener recipe as well.
Conclusion: Does this detergent work?
People always ask me, “Will homemade soap work as well as a store-bought product?” The answer, “YES! It will.”
My daughter’s chocolate stain on the left and after using this detergent in the wash. The stain lifted and the shirt was saved. If you need need extra help lifting a stain, you can also use my homemade stain remover first.

Homemade Liquid Laundry Detergent Recipe
Equipment
- 1 large saucepan or dutch oven (big enough to hold 15 cups of liquid)
- storage jars (such as 2 half gallon-size glass mason jars, 1 gallon-size jar, or reuse an old detergent bottle) for storing the laundry soap
Ingredients
- 1 cup borax
- 1 cup washing soda
- 1 cup liquid castile soap unscented or scented
- 15 cups water divided
- 50 drops essential oil optional for scent
Instructions
- 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.
- 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.
- 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.
- 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.
- As the soap sits, the mixture may form into a gel and become chunky. There may also be liquid and gel separation, simply stir or shake. This is normal.
How to Use
- For top loading washer machines, use 1/8-1/4 cup. For a front loader, use 1-2 tablespoons. Add the detergent to the liquid soap compartment of the washer.
- Stain Treatment – Use a small amount of soap directly on the stain, scrub or rub the stain with a cloth. Repeat as needed, then wash the garment. Or use this stain remover spray.
- Laundry Softener – This laundry detergent may be used with a fabric softener. I use vinegar added to the softener compartment or this salt scent booster & softener added directly to the wash basin before running a wash cycle.
I substituted borax for baking soda and added some Epsom salt to enhance the cleaning in color retention. It is separating super bad after sitting for a little bit. Anything I can do to help that?
Hey Claire, Separation is normal. Just stir or shake as needed.
According to the environmental working groups website EWG.ORG Borax is not a safe ingredient, someone recommends LA’s totally awesome oxygen, wish you well
Okay thanks for your opinion, Kevin.
Is this safe for septic systems and grey water systems?
Hey Claire, I don’t know.
Do you have this recipe worked out for large batches?
Hey Theresa, I don’t recommend making a water-based product like this in large batches, unless you plan to use it quickly. There’s too much risk for bacterial growth. That said, you could always double or triple the recipe amount.
