DIY Natural Laundry SOAP

If you’re anything like me, you’re always trying to figure out a way to spend less money. My paycheck goes towards food and household needs for my family of five. Every so often I take a look at what we are spending our money on. I have noticed, the things I know deep down that we can cut… are the things I hold back on buying until the very last minute.

One of these things…. laundry detergent. It’s a necessity after all. We need to have clean clothing, sheets and blankets. I tried to figure out couponing because a high-school friend of mine told me she hasn’t paid a dime for laundry detergent in 3 years! WOW! But let me tell you, couponing is so confusing to me! I spend about 3 hours finding deals, printing, cutting, searching… I forgot the coupon I could have used (that would have saved me $2), and the products that I didn’t need took another 15 minutes to find at the store, and they were out of stock.
I was covered in coupons that I had no idea how to organize… let alone read and find the corresponding product at the store with kids in tow… I decided couponing wasn’t for me. What about DIY? I freakin’ love DIY, but will I have time for that?Answer… Yes!

Two things led me to this fantastic discovery:

1: My MightyFix. I LOVE MightFix! I’ve been a subscriber to MightyFix for over a year, I was wishing for dryer balls. And then it happened! I got drier balls in the mail! (More on drier balls later) I like having a fresh scent to go along with my clean laundry, so I ventured into essential oils that you can drop on your balls (tee-hee), before your dry cycle.

At first, with excitement and curiosity, I picked up lavender and tea tree oils from WholeFoods. Along the way, I discovered MUCH better oils to use, more on that later…

  • Lavendar: for my laundry, it’s said to have a calming effect. With 3 boys to raise… I welcome all calming ingredients.
  • Tea Tree: Because I heard it has cleaning properties – a total impulse buy

2. Pinterest. Now that I have this bottle of tea tree oil, what do I do with it? Thank you Pinterest for making it incredibly easy for this visual learner to find and save information. I searched tea tree oil, essential oils, and dryer balls. I stumbled upon pins about DIY laundry detergents. (insert curiosity)

I read through a couple posts – some sort of complicated, or maybe too wordy and hard to follow. Then I found the one… by

I pinned it twice by accident, so I knew it was the one. I did the math and realized I would probably need 2 batches per year @ $20 each batch?! That would end up saving me around $200 a year! It takes 13 minutes to make? Game on!

The longest process was shopping for the ingredients, because I wanted to price it all out. I had a gift certificate for, but they tend to be pricey (only really reward new customers). I found everything within what priced out between and For some reason Target had baking soda at 1/2 the price Walmart listed.

Once I had all the ingredients, I was ready to rock!


My 5 year old helped me shred the soap in the food processor (which cleaned up very nicely and didn’t harm my appliance). From start to finish (opening boxes to everything cleaned up) it was 20 minutes! Done!

I made it easy for you, if you trust my pricing skills… if you find better prices please let me know!!

Ingredients, prices and directions:

  • 1 box Arm & Hammer Super Washing soda, 3lbs 7oz
    $3.97 at Walmart
  • Baking Soda, 4lbs
    2lb boxes for $1.29 each at Target
  • 4 bars of Kirk’s Original Coco Castile Soap
    2 3-packs for $3.28 each at Walmart
  • 1 container of Oxyclean Baby
    $8.18 at Walmart
  • 28oz of Epsom Salt (for softener)
    Picked this up at the grocery store, not sure the price


  1. Shred the castile soap in your food processor (shred attachment)
    1. My food processor is fairly new, I risked it and it worked fine for me. The post says to use caution, so use caution…
    2. You could use a manual cheese grater, it will add more time (still worth it I think)
  2. Grate the castile soap to a powder-like consistency (standard blade)
    1.  I did a few batches of the grated castile soap with baking soda
  3. Mix all the ingredients together
    1. I purchased a tupperware container for storage and shook it up


That’s it! So incredibly easy!

How it Works

I use 1-2 tbsp per load. Typically 2 tbsp because I always have full loads.


My entire house has a new freshness to it as well. The baking soda is said to be an odor neutralizer, and I have noticed an improved level of freshness in my whole house.

Cleans Well Too!

There is some controversy with this… that I just learned after drafting this VERY FIRST POST! (WAH) I am fresh off making a year supply of detergent, and I read a post about how DIY laundry detergent is not good after all. The post I read was very scientific, a little over my head. I decided to still share this because after a year of using it – I feel good about sharing.

year-of-laundry-soapOne year of detergent!

It cleans so well! My toddler rolls in dirt, and his clothes come out spotless. The whites are very white, I haven’t noticed any fading with the colors and my baby’s cloth diapers are clean as a whistle. This is all I have used in the past year, I still recommend it… I just will now also recommend reading the negative info to make an informed decision. Going forward, I will be sure to call this laundry SOAP and not detergent… because I now understand that it’s not a detergent, but a soap.

I am still so impressed with this.Making this change was one of the key changes in my journey in removing toxic chemicals from my home.  I hope you take the “risk” and try it as well.

  • Save some money
  • Go natural
    • Each ingredient has a grade A EWG rating
  • Smell great!

PS. I do feel calmer working with all these delicious lavender cloths from the lavender scented dryer balls. Sure bonus. I have tried several brands of oils, and feel I’ve landed the best one… more on that later.

PPS. I sometimes forget about the laundry and have to do a rewash… it happens. This new detergent passes the sniff test even better than commercial brands. Less rewashing! Hooray!
