Homemade Laundry Detergent Recipe


As I’m starting to branch out into more money saving advice, not just for food but budgeting in general, I’m excited to share my latest recipe with you.  That looks like grated cheese in the photo, but it’s actually soap!  I’ve started making a lot of my own household cleaners and detergents to save money, and one of my favorites is laundry soap.  It’s really easy to make, does a great job cleaning your clothes, and totally saves money even over buying the large bulk amounts of laundry soap. There are just three ingredients (and water) in my homemade laundry soap.  I researched a lot of different ways to make laundry detergent and found that this one was the cheapest and the easiest for me to store.


For soap you need a plain soap like Ivory, a laundry soap like Fels Naptha or even better, homemade soap!  My sister in law Heather actually makes soap, really good stuff!  You can get pre-grated plain laundry soap made with olive oil in her etsy shop.  One batch of that can make you two batches of laundry soap.  If you’re not in the mood for hunting down all the ingredients at the best deal, she also sells an easy laundry soap kit that will still give you a great deal for an all natural scent free laundry soap.


In addition to 2 ounces of grated soap, you’ll need washing soda and borax.  You can buy both of these online but the cheapest place I’ve found them is ACE Hardware.  If the ACE store near you doesn’t carry them, you can even order them on their website to be delivered there.

A 4 lb 12 oz (or 76 oz) box of Borax is $5.49 at my local ACE, which means it’s 7 cents an ounce.  A 3 lb 7 oz (55 oz) box of washing soda is $4.79 so that’s 8 cents an ounce.  You can typically get plain soap for anywhere from $1-2 an ounce.

So one batch of laundry soap from this recipe cost me 21 cents in Borax, 40 cents in washing soda and $2 in soap.  That’s $2.61 for 76 loads or 3 cents per load!!!!


Yes, that sounds crazy cheap, but is it actually cheaper than store bought laundry soap?  We used to get our laundry soap at Sam’s Club, and it’s a pretty good price if you’re going to buy it.  Their cheapest I’ve seen is “All” brand, which comes out to 10 cents per load.  Now 7 cents might not sound like that big of a difference, but let’s do a little more math.  Hang in there!

I don’t know how often you do laundry, but between us and our two exchange students, we do at least 4 loads a week.  That means in one year, if you’ve thrown in an extra couple loads for bed sheets we’ve spent about $6.50 in our homemade laundry soap.  Doing that same math, I would spend $21 a year on laundry soap.  Okay, maybe still not that shocking, but over time it adds up.  I’d rather have that extra $14.50 a year for fun money!

Some people have said that $14.50 a year isn’t worth the time it takes to make, but what if the cheapest detergent brand doesn’t work for you because the scents and other additives.  A lot of us have very sensitive skin, and this is a big part of why I started making my own homemade laundry soap.  Sam’s Club was the cheapest place I found an unscented, dye-free laundry detergent, and that came out to a whopping 33 cents a load!!!  That means spending at least $75 a year on laundry soap.  Now we’re at $68.50 in saving a year.  Can you see why I switched?


The bottom line is that it’s really easy to make your own laundry detergent.  Making it yourself is just one more way to save a little bit of money, and that adds up in the long run.  By saving a few dollars on things like homemade laundry detergent, homemade mayonnaise, homemade potstickers (items I might normally buy in the store) I can shave up to at least $100 a month off of my budget!


I’ve got a bunch of other household supplies I’m working on homemade versions of.  Do you have a favorite homemade cleaner?

  1. Making homemade things are great! We’ve made laundry detergent and it works just as good. It’s also nice to know that the soap doesn’t have a ton of chemicals in it. Also, it’s one less thing to drag in from the store since the washing soda and borax lasts soooooo long (unless you’re using it for other purposes!)

  2. What kind of storage container did you use? That’s my biggest problem with making my own homemade soap – something big enough to store it in.

  3. I stored it in my old laundry soap jug which works great. If you don’t have one big enough you can try a few different ways. You could store it in a two gallon bucket with a lid (from a hardware store) or use a couple empty milk or juice jugs that have been well washed. If using two 1 gallon jugs, just pour 6 1/2 cups of hot water into each jug and then pour half of your soap mixture into each.

  4. I use a food processor to grate the soap ( I use castille soap-Fels is toxic plus it comes in tons of scents-tea tree, mint etc…) and then put it all in the processor and whiz til it is fine. No need to cook super easy-just wash that processor!
    Make a double batch and you are set for a while.
    2 cups borax, 2 cups washing soda, 1 bar soap makes a single batch-easily fits in an old quart yogurt tub or the like-use a soup (dinner) spoon per load. I find all ingredients at the grocery store in Oregon.

    • Daphne this is definitely a low suds soap. I have read on several forums people with HE machines have used homemade laundry soap of borax, washing soda and plain soap with no issues.

  5. The best all-purpose cleaner EVER is one a friend of mine taught me to make. It takes 2 minutes, costs about 5 cents a batch, works like a charm on practically every surface (including walls and painted woodwork) and you can choose the scent. The recipe, from “Better Basics for Living” can be found here:


    And the thing is that if you have the ingredients for the all-purpose cleaner and a little vinegar, you have everything you need to make cleaners for 90% of your house: http://consciousshopper.blogspot.com/2010/02/recipes-for-homemade-household-cleaners.html

  6. You’re always so creative. This sounds very smart and I agree, it’s especially fantastic for those with sensitive skin. Have you tried it against something like Tide to see how it compares in stain removal.

    • Oooh, I’d like that too. Let me do some research. We’re almost out of shampoo and conditioner so I’ll start experimenting when it’s gone.

  7. I know I’m a few months behind here – I clicked through some of the links in the comments, and am now wondering about a toilet bowl cleaner? I use Ajax or Comet, whatever I find @ Walmart. It usually does a pretty good job (not perfect), but was wondering if there is something people use for that, a more natural solution? I’ve never used a liquid (not sure of a good container that would squirt up under the rim etc), but might be willing to try..


    • I’ve heard that 1 part baking soda to 4 parts vinegar can work well but I haven’t tried it yet. My husband always cleans the toilet!

  8. I’ve been using this exact same recipe for about 2 years now…it is so cheap, easy and yes, gives you a wonderful feeling of self satisfaction. It really is better for the environment and your family’s health. I love to see others that have kicked the dirty little “name brand” habit and come over to the clean side!

  9. Question on the laundry soap. 1/4 cup per load. Assuming that is a large load?

    After I have it mixed and using it, I notice lots of borax or soda stuck to the side of my 2 gal container, is that normal? I have made this 4 times now. I like it, but wonder if I am doing something wrong. Thanks.
