3-Ingredient DIY Liquid Laundry Soap That Works

A few weeks ago I decided to try another attempt at making my own DIY liquid laundry soap. I had actually tried another recipe a few years back with no success. It was so bad that my wife all but forbid me to try it again. 😉 Ok, it wasn’t THAT bad but the recipe I tried–which supposedly made something like 10 gallons of laundry soap if I remember right–was just way too watered-down to be worth a darn.

And, of course, there was the grating and boiling of laundry soap bars that wasn’t much fun either. So, I searched and I searched for a recipe that looked like it would work for us. No doubt there are MANY recipes out there. Fortunately, this one is very simple to make and had promise. I should point out that this recipe is quite a bit watery too but seems to work better than the other recipe I tried… and it still actually has plenty of sudsy bubbles. 🙂

DIY Liquid Laundry Soap Ingredients

You’ll want to adjust your recipe quantities to fit the container you use but I wanted my recipe to refill one of those large 200+ ounce jugs we use. As such, I needed to make roughly one and a half gallons worth of soap. To do so I used:

  • 1/2 cup borax
  • 1/2 cup super washing soda
  • 1/3 cup of Dawn dish soap (I used Ultra Dawn but regular may work just fine too)
  • 4 cups hot or boiling water + enough cold water to fill the jug

DIY Liquid Laundry Soap Directions

  1. Add 1/2 cup Borax and 1/2 cup of Super Washing Soda to a large mixing cup or bowl. I used a four-cup mixing cup but probably would have been better off with a slightly larger option. The other recipes I found said to use boiling water. I choose to use very hot tap water which worked well enough but I did notice that the borax and washing soda didn’t completely dissolve which required me to add another two cups of hot water to dissolve the rest. No big deal, just something to note.
  2. Add the diluted borax/washing soda mixture to your container then add 1/3 cup of Dawn dish soap. Replace the cap and shake well. You’ll see a lot of sudsing but that’s ok.
  3. Add cold tap water until the rest of the bottle is nearly full. As you can see suds began pouring out.
  4. The suds continued to pour out and wound up all over the bottom of my sink. At least my sink was going to cleaned well. 🙂
  5. Label the jar with the ingredients (or write down wherever you prefer) and begin using about 1/2 cup per load (adjust more or less as needed).

Thus far we’ve used about half the bottle of our DIY liquid laundry soap with no problems in the washer or with our clothes. Granted, we don’t get our clothing super dirty so I can’t say for sure how well it works on grungy, soiled clothing. That said, for normal cleaning duties it works just fine and is certainly less expensive than store-bought detergent.

    I know this is an old recipe but can you use this soap in a septic tank?

    1. I don’t see why not, but I would reach out to a local septic company to be sure.

  2. Cheryl

    There was a hidden tip…I love the idea of writing the recipe on the container. I hate having to search pinterest every time I need a DYI recipe!
    Thanks!

    do you ever put essential oils in your mix? If so, which ones? Would it hurt to add them also?

    1. I never used essential oils in my laundry soap but I don’t see why not. The only concern would be whether or not a person is sensitive to them since the clothes contact skin. Perhaps an oil like lavender would be a good choice but that’s up to you to decide what smells pleasant without being overbearing.

    The s is not compatible with my Maytag HE washing machine. It lights up and states the problem is use HE detergent
    Anyone else have the same issue with the computerized washing machines??

    1. Yes, I’ve heard that can be a problem with newer HE washers or, at least, I’ve heard you’re not supposed to use it with HE washers.

      try a different soap rather than a sudsing detergent.

    So its about one gallon of cold water? Am I understanding that part correctly?

    1. The recipe is for a 210 ounce jug. Less roughly 10 ounces of ingredients you’re left with about 200 ounces of total water. At 128 ounces per gallon that equals about 1.5 gallons of water. Honestly, you could probably be off quite a bit in the water used and still have a sufficient laundry soap.

    I’ve been using this recipe for a couple of years, but I use the Kirkland (Costco) brand “environmentally friendly” dish soap. I made mine sized for the (I think) 1 gallon white vinegar jugs and use a little more than 1/4 cup of borax and washing soda each and about 2.5 T of dish soap. I dissolve all 3 ingredients with boiling water in my 4 cup glass measure and just stir them gently to mix. If you stir gently you don’t get too many bubbles. WAIT TILL IT COOLS, before pouring into your large plastic jug! Then to make sure I get all the residue and cleaning goodness from the 4 cup measure, I fill it with tap water, swish it a bit and use that method to fill the big jug. If you do it carefully and use a spoon to direct in the bubbles from each round of rinse, you won’t get the bubbling over problem and you’ll get every bit of soap/detergent from your glass measure.

    I would strongly recommend BOILING water to dissolve the washing soda and borax. The times I haven’t, even though they seemed dissolved, I eventually got flakes of hardened stuff in the bottom of the big jug.

    BTW, we have a Kenmore HE front loader machine and the only issue I have is that it is so thin of liquid that it tends to run out from the dispenser spot too soon unless I really press it down.

    1. Walmart has it too.

    One more thing: I hated the wet, soapy residue dripping from the measuring cup that we kept on the shelf by the washer. Since I replaced liquid fabric softener with white vinegar, I use the same measuring cup, and it rinses it out nicely. I also recycle the gallon vinegar jugs as laundry detergent containers.
    Our laundry, especially sheets and towels, has never smelled so fresh. Hanging it outside in the sun makes it even better!

    Good recipe. Fyi, if you add the Dawn at the very end after adding the cold water, it won’t bubble over everywhere. To dissolve the dish soap, just gently roll the tightly-closed jug back and forth between your hands.
    I’ve been using this recipe for a year or so, and I like it a lot. I also add 15-20 drops each of rosemary and lavender essential oils for their antibacterial effects.

    1. Now that is a brilliant thought! Thanks, Robynne… I’ll give a shot the next time I make up some.

    how much would some one use if they wanted to make this in a 5 gallon bucket? im just starting out wanting to try this

    1. You’d probably have to triple it if memory serves. My advice would be to make LESS and use it for a week or two to ensure you really like the recipe before making so much.

    Where can I find “super washing soda”? I don’t believe I’ve ever seen it before. Thank you!!!

    1. Should be sold at Walmart for sure, I know I’ve bought it there. You can always buy on Amazon using the link above too.

    I have been using this recipe for years. Saves a lot of $$

    1. Glad to hear it works over the long haul. Thus far we’ve been pleased. Granted, I’m not quite sure whether Dawn dish soap is the best thing for our clothes but thus far my wife hasn’t complained so I might be on the right track. 🙂

    Do you think that recipe would be OK to use in a machine that only uses HE laundry soap?

    1. The recipe that I found indicated it’s fine for HE machines but I haven’t tried it myself as we don’t have one of those. Here’s the original recipe: http://www.backdoorsurvival.com/homemade-laundry-soap/

        If the washing machine in the picture is yours, you actually do have a HE machine. Trust me. We’ve had the same one for years. Thanks for the article. I’ve been making laundry soap for a couple of years but haven’t really been satisfied. I’ll try this one next.

        1. Ok, I’ll take your word for it. 🙂
