Homemade Laundry Detergent

homemade laundry detergent

A few years ago, I decided to try my hand at homemade laundry detergent. I was interested in saving money, but I was also tired of paying more for laundry soap designed for “sensitive skin.”

The recipe I started out with was a liquid laundry detergent using borax, grated soap, washing soda and hot water.

It worked well – my clothes came out clean, though my cloth diapers always needed an extra rinse and Bac-Out to come out smelling fresh.

However, I wasn’t fond of the way it clumped up and I’d have to shake it to evenly distribute everything again.

We shall not discuss the time I shook and the lid wasn’t properly secured …

After that batch ran out, I knew I wanted a powder. Over the years, liquid laundry detergents meant another mess for me to clean up and I was done with it.

I found this recipe from my friends at diyNatural and used it for quite a long time (using grated castile soap). It was very simple and used the exact same ingredients as the liquid laundry detergent had.

However, after a while, I noticed that I’d have to do an extra hot soak to get the smells out. Four kids, a crunchy mama and a husband who loves to run create some interesting smelling clothes.

I switched from a castile bar soap to Fels Naptha, which was much cheaper. I was hesitant at first because of the fragrance, but the smell doesn’t linger (or is maybe hidden by my essential oils) and it does not irritate my skin, which was my main concern. The new soap helped, but by that time I was itching to create something new.

It was time to experiment.

I needed something that would be tough enough on the smells we were dealing with and, ideally, something that wouldn’t require making new laundry detergent every month.

Fortunately, I found a recipe that sounded promising. It promised to last for a year, so I made the recipe and sold 1/3 to my mom and 1/3 to my sister-in-law (they like my homemade detergent but don’t want to make it, so I earn all the money for the ingredients and a little extra).

They loved it. But I didn’t.

The recipe called for a fabric softening product to be added that I didn’t like (they did) and I couldn’t stand the smell of it (which is why I like natural products – no noxious smells). Thankfully, I added the fabric softener after I took some laundry detergent out for myself, and that actually worked pretty well.

I ended up tweaking the recipe a little and have a powder laundry detergent that handles our tough smells (and stains) well. It also lasts me about 4 months.

Homemade Laundry Detergent

Here’s what you need (I get almost all of the ingredients in the laundry soap aisle of my local Kroger):

  • 1 box Borax powder (yes, I’ve read the arguments for and against it and still use it – it has not caused us any problems)
  • 1 box Washing Soda
  • 3 bars coconut oil soap (or try it with this olive castile soap – use coupon code SM1 to get $2 off a pound of castile shreds)
  • 1 32 oz. container oxygen bleach (I like this one)
  • 40 drops essential oil (I like to switch up combinations and use lavender/lemon, lavender/wild orange, peppermint/orange, etc.)

Grate the soap and then run it through your food processor to break it down into smaller pieces. I usually do this in batches, using 1 cup of oxygen bleach and one grated bar of soap – my machine seems to like that more. I just do the essential oils in one of the batches.

My kids love making this stuff. And we all cover our mouths with our shirts when we’re pouring all of the powders.

I pour each batch into the bucket I store the laundry detergent in (I use one with a lid). After I’ve added the grated soap/oxygen bleach/essential oil mixture to the bucket, I pour in the box of borax, the box of washing soda and any remaining oxygen bleach.

I then secure the lid (tightly!) and start shaking it to get everything mixed up. I usually ask my husband for help, too. And, for good measure, the kids shake it up a little as well.

To use, I add 2 tbsp to each load of laundry. 

Update 4/16/15: Reader Karen had a great recommendation:

I use almost the identical recipe but I add 1 lb box of baking soda.  I also made my own softener to add with the detergent.  I used epsom salts and put it in a large jar and added the essential oils to it, sealed it up for about a week before I made the detergent and then added it to the detergent.  I had originally used the purex crystals but I didn’t like the the coloring added to it….and I wanted to have a greater choice scents that I liked.  Anyway it has worked out beautifully and if I don’t want a scent then I just use the plain epsom salts and it really softens clothes well !  I so love this site !!!!

Have you made your own laundry detergent?

    I’ve made my own laundry detergent similar to yours but w/o the bleach. I had mixed feelings about it, maybe because I was cleaning cloth diapers using a front loader and wasn’t crazy about how they were coming out. Now we have a top loader again and I feel this gets things cleaner.

    I’m always looking for new recipes and appreciate when someone explains the science behind them. I recently came across this recipe (http://www.mommypotamus.com/homemade-natural-laundry-detergent-made-easy/) for laundry detergent with JUST washing soda (no borax, but not because it’s harmful) and coconut oil soap, essential oils optional. I plan to make that and use a Downy ball with white vinegar rinse, maybe some epsom salt fabric softener.

    I love this recipe. It does last about 4 months. I followed the advice of one of the replies. To mix it up in a trash bag. it was a lot easier. I also store it in glass mason jars. That way I’m not prying the lid off of my 5 gallon pail. I have tried other recipes. This one works on my sons filthy, smelly work clothes. I will always use this recipe! Thanks for sharing it!

    Your recipe is almost exactly like mine except I also add a box of Arm & Hammer baking soda and omit the essential oils from the detergent but add the oils straight to the water when filling the washer. I love it because it costs me less than $20 and lasts up 4-6 months!

    I’ve been making my own laundry and I line dry them. I always ready about line dried clothes smelling so great but mine always come out stiff and don’t smell ‘fresh’! I am really excited to give your detergent a try! I struggle the most with my kitchen towels and rags and getting them to not have that soured smell after being used! Do you have a fabric softener recipe you recommend? I just hate having all of our clothes so stiff once they are dry.

    Love that your kids are involved. I was reading through the comments and am glad this can be used on cloth diapers! With baby #2, we are spending far too much on laundry detergent with the increase in laundry!

    How much did you save by buying all that stuff for the mixtures plus mixing them and experimenting with the new ones?Does this mixture play well with the laundry machine? I know that I tried a few things with mine but the quality of the manufacturer was extremely low and something wasn’t right with the filters and stuff. I didn’t really bother to know what but I tried not to play with it anymore.

    What size container do you store your powder detergent in? This doesn’t seem to need the 5 gallon bucket that the liquid detergent needs, but what works for you?

  8. says

    Hi Rachel,

    It makes a bit over a gallon if I remember correctly (I haven’t put it in a gallon jar in years.) I usually divide it up into a few decorative containers and pull out a new one as I use it up.

    Hello Nina, I have sensitive skin, too. My daughter has more sensitive than mine. In my family we always use homemade soaps and cleaners. It is really big fun when we are making them. My daughter loves to help me , too. Greetings!
