DIY Homemade Laundry Detergent – Cheap and Green {free printable}

Making your own laundry detergent from home is surprisingly easy and cheap, and with this recipe, there is no soap grating necessary! It uses just three ingredients and works like a charm – I know because I’ve been using it for nearly a year and my clothes always come out clean and soft. I provide two versions here – one with and one without Borax.

Homemade Laundry Detergent with Dr. Bronner's Castile Soap

Now updated with a free printable label – it’s pretty and you never have to look up the recipe again

Making your own detergent also just makes logical sense if you want to save money. Why? When you buy a cleaning product, especially laundry detergent, you’re mostly paying for WATER. $18 for a gallon of mostly water if you buy Tide. Here’s a way to save those dollars and make it yourself at home in just five minutes!

So, once my gallon of Dr. Bronner’s Castile Soap arrived in the mail from Amazon, I went on a mission to see how many green cleaning products I could make myself using my new, supposedly magical, soap. One of the items on the list was homemade laundry detergent! I wanted something that would be safe for the ground water, environment, cheap and gentle on my clothes. I scoured the internet to find a great recipe, because to my disappointment, there are no laundry detergent recipes in my handy “Clean House, Clean Planet” book (except to use Dr. Bronner’s Sal Suds in an undiluted form – NOT cheap). So, I came across this recipe, from the Backwoods Home magazine website, and after two months, am still very happy with it! And I even have very hard water (oh the fun of living in the Marcellus Shale!)

According to their article, this homemade recipe costs a tenth of the cost of store-bought laundry detergent. I’m too skeptical to believe things like that without checking it out for myself, so I set out to see if they are correct!

Homemade Laundry Detergent Ingredients and Supplies

Just 3 ingredients – Super Washing Soda, Borax & Castile Soap (optional use of an essential oil like Lavender for fragrance)

 

How Cheap is this Homemade Detergent?

1 box of Super Washing Soda (where to buy) (55 oz.) = $2.69 (at Wegman’s) 
1 box of 20 Mule Team Borax (where to buy) (76 oz.) = $3.99 (at Wegman’s) or 4 lb. Bob’s Red Mill Baking Soda (where to buy) = $7.96 (Amazon) or $1.99/lb.
1 gallon of Dr. Bronner’s Castile Soap (128 oz.) = $51.99 (at Amazon.com with free shipping)

To make two gallons of the detergent you use:
Super Washing Soda (you get 13.75 uses out of one box) = $.20 a batch
Borax (20 Mule Team ) (you get 19 uses out of one box) = $.21 a batch or $0.66 a batch with Baking Soda
Dr. Bronner’s Castile Soap (you get 21 uses out of one gallon) = $2.47

Add it all up, that’s a mere $2.88 for two gallons, or 96 loads if you use the suggested 1/3 cup a load. 

WOW!

Compare that to Tide 2x Ultra Concentrated: 1 container of 150 oz. (or 96 loads) of Tide costs = $17.99
And Tide is not green or safe for the environment. Not only can you help the environment and wash clothes that are safe for your little ones (i.e., hypoallergenic & gentle), you can save $15.11!

You save even more if you compare it to a green (eco-friendly) laundry detergent.

A Note About Borax

Borax is controversial in green circles and I have found arguments for and against it. When I originally wrote this recipe, I did not know that the EWG gives Borax a rating of F for reproductive and organ toxicity – yikes. Apparently, it does not harm the environment, though, which is good. I use the EWG (Environmental Working Group) to research the safety of many products, so this was quite a find. I have decided not to use Borax any longer based on the EWG’s rating. The good news is that baking soda and super washing soda or a combination of both are excellent substitutes for borax and are readily available in grocery stores.

Supplies

  • 2 one-gallon containers in which to store the detergent (I recycled an old laundry detergent container and a vinegar jug)
  • A measuring cup or two
  • A two-gallon bucket or larger (I used my old mop bucket)
  • Funnel to pour the detergent from the bucket into the containers (not necessary but certainly helpful!)
  • 1 hand blender or immersion blender

The Secret? Mix with a Hand Mixer or Immersion Blender!

I have experimented with how to keep clumps from forming for years with this recipe and I finally figured it! I used to boil it down on the stove, make the powders dissolve with hot water (doesn’t work at all!), and stir like crazy. I finally got smart and decided to try my immersion blender. Perfect!

Homemade Laundry Detergent Using Castile Soap
 Dr. Bronner’s Castile soap is the BEST – it is organic, pure, contains no SLS (sodium laureth sulfate) or any other sulfates so it does not dry out the skin and is gentle on both skin and clothes. I love the company – they are uber crunchy and fight for things like the environment and animal rights!

How Long Does it Last? How Many Loads?

This batch lasted about two months for a family of four, and even included a three day visit from four girls in my family who love to wash clothes (and have lots of them!). I find it works for about 96 loads, which for us is about 2 1/2 months, so I don’t have to make it very often!

I find this detergent works just as well as Tide, All, and Arm and Hammer’s detergents, all of which I’ve used. The website suggests using it as stain remover as well and I tried that with no luck at all – stains didn’t budge a bit, even after soaking for days in the detergent.

How Much To Use in the Washer:

I use 1/3 cup like the website suggests (and I do have an HE washer) and find it’s important to mix the detergent before each use. I swish my container around so it doesn’t get too sudsy, and it works like a charm.

Overall, I love this detergent and how much money I’m saving on it, while doing my part to be friendly to nature and our health.

  1. Amazing recipe. Borax is not so toxic. It is important to prevent children of swallowing or licking it. You could use it only for things which are impossible to swallow or lick. I LOVE YOUR BLOG. Thank you for sharing your post. Best regards!

  2. Hi, I just thought I would add a quick note about borax. The reason it was given a grade of F by EWG was due to its potential, although untested (and I certainly wouldn’t test it!), harmful effect on reproductivity and endocrine production.

    However, just to be clear, borax must be ingested to replicate the harmful effects that lead to its grade of F. Obviously ingestion is NOT recommended, so if you are worried about it being within the reach of children, it may be best to avoid it.

    Borax does not absorb very well through the skin, if at all, and the dilution of borax in the recipe, plus the added benefit of rinsing your clothes during the wash cycle essentially negates the harmful qualities of borax.

    If you are concerned with using borax for non-health reasons, or other personal reasons, that’s completely understandable. I just thought it would be good for readers to know that as an additive to the laundry detergent recipe, the risk posed is almost non-existent…unless you drink your laundry detergent, which would not be recommended regardless of what ingredients were used.

  3. Wish I could post photos here but can’t see how. At any rate, I have such an easy, proficient recipe for laundry soap. Been using it for over a year and my husband’s South Florida Deputy Sheriff’s uniforms have never looked (and smelled) cleaner and brighter. My work suits and career clothing, our T-shirts, shorts, regular lounge and informal wear as well as bathing suits, towels, dog’s bedding and even my ahem “delicates” are looking (and smelling!) fresher, brighter and lasting longer. I’ll never go back.

    LAUNDRY SOAP
    3 T Borax
    3 T Washing Soda
    2 T Liquid dish soap
    8 C Filtered water

    You will also need a 1/2 gallon container. I reused an apple juice bottle. A funnel is also very helpful.
    (1) Measure the borax and washing soda into the bottle you are using.
    (2) Heat up 2 cups of water and pour into the mix.
    (3) Once dissolved, add in filtered water to just about fill your 2 quart container. Shake it up good. There will be no lumps or “floaties”.
    (4) Top off with 2 TBLS Dawn Dish Soap and just gently turn the jug a few times to get a good mix. The original article I learned this from said to use 1/4 to 1/2 cup per load in the HE washer. And that’s just what I do!

    I use vinegar for the fabric softener cycle and there is no need to add fabric softener sheets to the dryer. If you want a bit of scent, a drop of two Lavender Essential Oil in the (vinegar) rinse is lovely.

    We have a 2 person home and strangely, do a heck of a lot of laundry. This jug lasts always one week and most times into the second week. Making a fresh supply takes all of 3 minutes.

    • Dawn dish soap is completely full of chemicals. Can you just sub the liquid castile soap for people who want a natural toxic free option??

      • Hi Melissa! The liquid castile soap I suggest in this recipe is completely natural and non-toxic, I don’t suggest using Dawn in this recipe. Are you referring to a comment that was posted?

  4. Hi all
    I see others are talking about boiling their laundry soap to make it. I don’t see this in the recipe. Should I have boiled mine?
    Thank you

    • Hi Eina! Well, I’ve gone back and forth on boiling it and at first, it helps to really emulsify the soap, but later, as it cools, it separates again and I still have to shake up the container before using. So, there really isn’t a need to boil the water.

  5. Hi there 🙂

    Wonderful recipe!!

    Thank you so much for sharing, very much appreciated!!

    I made mine 12 hours ago (very exiting 🙂 !!

    I only used 1 gallon of water (16 cups)

    Is it ok to add the extra water I missed when I use the liquid (eg double the amount of liquid by mixing it with water)

    or would it be better and necessary for the recipe to work to pour all the washing liquid back into the bucket and add the extra gallon? Or id it too late for that?

    Many thanks 🙂

    • Correction:

      I mean halving the amount of detergent recommended and thus adding /doubling it with the extra water I missed

      OR just pouring half the recommended amount of detergent straight into the washing machine as mine is now more concentrated?

      Complicated 😉 Sorry!!

  6. Nicole cent says:

    Any thoughts about how this should go into the washer? I have the kind where you load the detergent into a little tray. Should I do that with the homemade soap or just pour directly into the machine with the clothes?

  7. I pour the detergent into the machine. I put vinegar in the softener spot in the tray.

  8. I have tried multiple laundry recipes at this point, and this one was a variation on the original that I’d tried. I found that the powders were not dissolving no matter how much I mixed with my mixer. So, I started over and threw the measured amounts in a mason jar with a lid and shook it until they dissolved.

  9. Thank you so much for this! I’m wondering how it works for you with dark colors?..
    i’m trying to find a natural recipe similar to woolite…
    Do you have any suggestion, please?…
    Thanks and God bless 😉

  10. All of my questions setthed-tlanks!

  11. Love this! Have been using this recipe since August 2015 and haven’t looked back. Thank you so much!

  12. I really like your recipe, but I don’t have a hand mixer or immersion blender. Do you think shaking it in the mason jar as suggested above would be enough? I realize I would probably have to shake it before I measure each time, but thinking that may work. What do you think?

  13. If you replace the Borax with Washing Soda, are you using 1 cup of Soda in this recipe?

  14. I just did this and it turns out very “liquid-y”/watery. Is that how it is supposed to be? Purchased liquid detergents are SO thick so I was sort of expecting it to be like that. Did I do anything wrong? It pours more like water than like syrup. And I only need to use about 1/3 cup per load? Thanks for any help

  15. Yvette Rose says:

    I don’t understand why you add baking soda to your recipe. Washing soda is nothing more than baking soda that has literally been baked to change the molecular structure. I’m not criticizing, I just want to understand. Thank you

  16. Just wanted to report back at how wonderful this recipe is! I did not have an immersion blender so I just used the container my previous laundry detergent came in and filled the bottom as the recipe calls for and I just shook it real good and all dissolved. Then I added the rest, and it is just wonderful! Smells great and cleans the clothes just fine. I am so happy to be making my own, and knowing what is in it. Thank you for this recipe!

  17. Mine does not dissolve at all! I tried boiling, stirring, and shaking. It crystallized and got really hard. What am I doing wrong?!

    • I’m really not sure, Laura, I think I’d have to know more about your process. It does not dissolve completely, that is true. But it shouldn’t harden or crystallize unless there is too little water.

  18. Kristen Dickerson says:

    What if you don’t have a hand blender or immersion blender? Is there another way to mix it well or do I just need to break down and buy one of these?

  19. NatureLover says:

    Hi there!l

    Thank you so much for your posts! Because of your post with the essential oil drops on wash cloths out clothes actually smelled nice yesterday! So thank you so much!

    I would like to make this detergent but we always like to add a up of Epsom salt mixed with drops of peppermint to soften and sanitize the socks, it works so well it actually brightens them! If I add that in the washer with this recipe, will it set it off balance? Is there a way to add my cup in with this soap recipe too? If at the very least for the softness the Epsom salt gives…(if you’ll tell me that the peppermint soap could replace the essential oil 😉

    Thank you so much!

    • Hi NatureLover! I’m not sure how that’ll work, to be honest, but I do think adding the Epsom Salts and peppermint will be totally fine with this detergent. Try it and see! I love that you use that to brighten and sanitize the socks – great idea!

  20. I have a dumb question – I have been looking for a recipe for a liquid (only because I have some liquid Castile soap that needs to be used up) laundry soap that does not contain water. I believe water kills the shelf life of any DIY product, is this true? I don’t have kids or a hubby, so I don’t have to do laundry every 3 days. Is it possible to just add a little Castile soap and washing soda to the water before putting the clothes in? Would that work? If so, what would the amounts be? Thanks for you help!

    • Sure, you could do that, but I’ve never read that before or heard that… I’ve used this recipe for years and it’s still going strong, water and all!

  21. Is this safe for HE washers?
