Making your own natural, homemade laundry detergent is one of the easiest parts of a transition to natural living. This natural laundry soap recipe a great way to save money on laundry detergent and is incredibly easy to make. This homemade laundry detergent post is an updated version of this recipe that addresses high efficiency washers and borax safety.

Why Switch to Natural Laundry Soap?

Conventional laundry detergent is loaded with chemicals like sulfates, fragrances, phenols and more. Many brands contain things like petroleum distillates, which are linked to cancer and lung disease. Fragrances in these detergents are made of a mix of harmful chemicals. (This is also why I make my own linen spray.)

Luckily, making your own laundry soap is an easy and fast process! You only need three basic ingredients to make either a powdered or liquid laundry soap:

DIY Laundry Soap Ingredients

  • Washing Soda (Arm and Hammer Brand available at most stores)Borax Powder
  • Borax (20 Mule Team Borax available at most grocery stores)
  • Bar Soap (Dr. Bronner’s,  Ivory, or other natural, unscented bar soap)

Washing Soda and Borax should be available at your local grocery store on the laundry aisle. Natural bar soaps are in the health, beauty, or organic sections of the store, or online. You can also add a couple tablespoons of baking soda to help freshen clothes.

Wonder What’s in These Ingredients?

Borax is a naturally occurring mineral made up of sodium, boron, oxygen, and water. It is an ingredient in most of the natural soaps available now (Seventh Generation, etc.) but it is much more inexpensive to make yourself. There are some concerns about the safety of Borax, but here’s why I feel comfortable using it, especially for laundry.

Washing Soda

Washing Soda, sometimes called sodium carbonate or soda ash, is made from common salt and limestone or found as natural deposits. If you can’t find this locally, you can make your own from plain baking soda with this tutorial. Here are some other great household uses for washing soda.

Dr. Bronner’s soaps are fair trade and made with vegetable castile soap and pure organic oils.

A Note About Soap vs. Detergent

All Natural Laundry Soap Recipes - two ways

As mentioned above, there is chemically a difference between soap and detergent. The advantage of conventional laundry detergents is that they are formulated to work specifically in washing machine environments. Many soaps are designed for skin and are not as strong. Some sources suggest that over time, natural soaps can leave buildup in washers.

I’ve found that while this recipe works well for me, it isn’t suitable for all water types and washer types. If you’ve used natural laundry soap and experienced clothes getting dingy, this may be the reason.

I’ve found one natural detergent that works brilliantly and can be used alone or in combination with homemade laundry soaps like this one. I often add 2-3 Tablespoons of Dr. Bronners Sal Suds per load as a natural detergent. Sal Suds gets out tough stains and odors and is still a natural product (though technically a detergent/surfactant and not a soap).

Don’t Want to Make it?

Homemade Natural Effective Laundry Soap Recipe

We usually make our own detergent, but for times when we are traveling or I haven’t had time to make it, I’ve found a few good brands of eco friendly laundry detergent that actually work (all received an “A” by the Environmental Working Group):

  • My Green Fills Laundry Detergent – Just a warning… after you try this laundry soap, you may be ruined for DIY forever. This is the best smelling non-toxic laundry detergent I’ve tried and it works well on tough stains and dirt. Similar to my favorite all-purpose cleaner, a huge bonus is their eco-friendly approach. The detergent comes concentrated in a small refill packet (hence the name) which you add to warm water in the provided bottle. Super smart!
  • 2 tablespoons Sal Suds + 1/4 cup Baking Soda or Washing Soda (highly effective and super simple!)
  • Ecover Zero Laundry Detergent– Works well, relatively cost effective and low/no risk of developmental or reproductive toxicity and cancer according to the EWG.
  • Emma Eco Me Detergent – Also rated well by the EWG and cleans up to 64  loads for $12. Good scents.
  • Planet Natural Detergent –  Relatively eco-friendly and cost effective at $9 for 32 loads.

Obviously, the most frugal option is to make your own, but these natural alternatives are a good choice if you aren’t able to make your own or don’t want to.

    I just tried making the powdered version of this recipe. I am confused as to how much volume 1 shredded bar of Dr. Bronner’s soap counts for? At first, I put it on the small shredder setting the in the food processor and it came out close to 2 cups. But then I put it through a regular setting to make it finer and it came out to 1 cup. So, I wasn’t sure if I should add 2 cups of washing soda and borax (each) or 4 cups each? Thank you so much for your help!

    Hi Katie. Although I plan to try soap nuts eventually, for now I’ve simply stopped using conventional laundry detergents and made my own using Kirk’s Coco Castile bar soap and Arm & Hammer Super Washing Soda. Sometimes I add Hydrogen Peroxide to the wash water as well, usually in the white or bright loads. I noticed right away that our dark clothing has faded very badly after only one month. Do you have any suggestions? Have you noticed any fading using either homemade detergent or soap nuts? I use 1-3 TBsp of dry mix depending on the size of the load. I’m rather shocked that our clothing faded so quickly, especially since we have hard water.

    I was wondering if this laundry soap fades dark or colored clothes? I would love to make some and use it but most of my clothes are dark due to work uniforms.

    Is the bar soap necessary or can the other two ingredients alone be used?

    My mother and sister have made the liquid for years. They have wanted me for years to make it and start using it and I finally did with this recipe. They use the fels-naptha soap, borax and washing soda. Theirs have always jelled. I made this recipe last week with the Dr. Bronner’s lavendar soap (the only thing that is different from their recipe). My is still just like water. It’s not jelled at all. I used 2 quarts of water to melt soap and 4.5 gallons of REALLY hot tap water. When mixed all together would total 5 gallons. Is this correct? This is the only thing that I could think of as to why it’s still water consistency and didn’t jell. I thought maybe I used to much water. Is there anything I can add to it to make it jell? Also do you have a homemade stain treatment recipe on your blog anywhere? I love your blog thanks for sharing all the great recipes!

    What do you think if I infused the water with something like lemongrass before hand? I would love to add some yummy smells to this w/o having to spend a fortune on essentials. – thanks 🙂

    First of all, a friend just turned me on to your website and I’m IN LOVE. I’ve found so much GREAT information! I have to say though, I’m a little surprised you’re using a recipe with Borax. Although VERY common in homemade laundry detergents, EWG (Environmental Working Group) has some pretty nasty things to say about it. It has received an overall ‘F’ rating for a number of things, especially developmental and reproductive toxicity.
    Just thought I’d share, and I’d love to know if you have any contraindicating info as well. Thanks for all you do!

    When I let the detergent sit over night I got this thick disk of gunk… then clean(ish) water on the bottom. Is this normal, or did I mess up somewhere? I used Zote bar soap per another recipe, and I followed the rather vauge instructions as closely as possible. I stired it all together like it says to do here and it seems okay but this is my first time and Im rather nervous.

    I use this recipe for powdered laundry detergent for all my laundry including cloth diapers. My baby is now 7 months old, and the diapers are really starting to smell as soon as they are wet. I have tried stripping them a few different ways–with vinegar, soaking in the tub, etc. (we have a front loader). Nothing seems to work! I use 1/8 cup detergent for each load. I think we have hard water, do you think that is the problem? I thought washing soda acted as a water softener. Do you have any advice? My poor baby stinks when he barely wets. I would love to hear any advice you might have.

      Try replacing any borax or baking soda with washing soda. Borax and baking soda are weaker water softeners than the washing soda. I’m not sure which type of bar soap you are using, but you might want to try a heavier duty laundry bar like fels naptha. It’s not as natural as castille, but it really gets the stains out. Also, you can try using warmer water. Borax doesn’t work well at all in cold water.

    Has anyone tried to make the liquid clothes detergent in a more concentrated formula? I was thinking of using 1/2 the water and using 1/2 as much per load. Will it still gell and work all right?

  13. Cheryl Avatar

    For the liquid recipe could you halve the amounts and it still turn out ok?

    I’m looking for a substitute for dryer sheets, but my HE washer LOCKS once the cycle begins, so I can’t add anything during a rinse cycle. Do you know of anything that works in the dryer, or if put in the washer along with the detergent? I have to put the detergent in the empty machine and THEN add clothes, according to manufacturer directions. Thanks much.

    1. abby Avatar

      Your washer should have fabric softener slot (same area as the one for detergent) that will get added during the rinse.

    2. Jenna Avatar

      If you use 1/4 cup of vinegar in the rinse cycle, it should take the static out of the clothing so you will not need to use dryer sheets.

      Love this thread…still trying to figure out which recipe to try, lol, but enjoying reading it. For the person asking about laundry smelling, I take lavender and put it into reuseable bags and toss it into the dryer. I have also seen a similar thing for sale at Trader Joes, and you use one bag for quite a few dryer loads before the smell goes away. I have very hard water in my area, and I saw a similar recipe using kosher salt…anyone tried adding salt?

        So I’ve been reading all of the comments too. I think if someone is afraid of using their hard water, thinking about going out buying distilled water, or the mixture turns out too runny – just boil your water first in a large pot. I made mine last night per directions plus I boiled my water and it turned out great! I also skipped the 5 gallon bucket and just used a 5 gallon water jug with a spout. Just shake to mix =)
        Have a great weekend everyone!

    I’m new to all of this. Could this recipe be used for liquid dish soap? Dryer balls were mentioned, any particular brand recommendations?

    Question, I was doing the math and granted I did add oxyclean because I read it really helps boost the cleaning, but it is still about 40cents a load. I do not want to mess with the 5 gallons of goo….. Any suggestion on cutting the cost? I use dr bronners soap after reading several posts! I love the way the clothes feel after a couple of washes they are super soft! I changed to natural soaps and laundry soaps after itching with all free and clear…which was about 11cents a load. Thanks for your help!

    Does FelsNaptha work as the bar soap? Or does it need to be one of the one’s indicated in the post. I can get Dr. Bronners but I find the FelsNaptha is already a great stain remover and cheaper than the Dr. Bronners. Thanks!
