DIY Simple Eco-Friendly Laundry Detergent


There are about a million different laundry detergent recipes out there so this should be nothing new if you are a forager of inexpensive DIY household recipes. This is my version, and I just made 3 batches this morning because it’s laundry day. It’s super easy, eco-friendly and inexpensive. You can even order the ingredients online and create the mix in less than an hour and get on with your life!


Grater – I set aside a cheap grater that I just keep in my laundry closet and only use for this purpose. You are only going to be grating soap with it though, so you can even just use your regular kitchen grater and rinse the soap off well when you are done!

Gloves – (Optional) I grated part of my fingernail into my laundry detergent this morning. Luckily it wasn’t part of my finger so gloves are a good idea if you are uncoordinated like me!

Container – An old laundry box would be a good re-purposed container. I use the larger plastic container in the photo to create my detergent and put a smaller amount  in the white container pictured (an old Oxy-clean container) on top of my washer for easy access.


1 Cup Washing Soda (sodium carbonate)

Washing soda works as a water softener, grease and stain remover. Apparently you can make your own from baking soda if you are having trouble finding it in stores.


1 Cup Borax (sodium borate)

Borax is a mineral similar to baking soda but stronger, with a higher pH. It’s antifungal, antibacterial, can dissolve dirt and remove odors.


1 Bar of Castile Soap

Castile soap is a mild soap made from plant oils.

Dr. Bronner’s Peppermint is my personal favorite because it’s eco-friendly and also smells great.


*Large Batches – I like to make large batches of this all at once using all the soap I have on hand. For instance, today I had 3 bars of soap so I grated all three bars of soap and added 3 cups of Washing Soda and 3 cups of Borax.


** Finding Ingredients – You can usually find all these ingredients near the laundry section. I was in Walmart a few days ago, and I found Washing Soda and Borax on the same isle as fabric softener and in the same area as baking soda, Oxy-clean and other laundry additives. The castile soap was in the bath/beauty section of the store. They did have a laundry soap – Zote, in the laundry section, but I was looking for a more eco-friendly option.


Grate the soap as finely as possible and add in the Borax and Washing Soda. Mix well. The soap will sink to the bottom of your container so just shake up the container before using.

Use 1 TBSP of laundry detergent per load. This detergent works great on baby clothes, gentle clothes, and is just fine for HE washers!



This detergent is low suds so it works great in high efficiency washing machines. I have actually noticed less build-up in my HE washing machine since switching to non-commercial detergent.



This detergent is extremely mild, and you could even use the unscented Dr. Bronner’s Castile Soap to keep this even more mild. The nice thing about this detergent is that it actually works for the whole family so there is no need for separate detergents.


COST: Approximately $.20 load ($42.37 FOR 6 BATCHES)

I like to figure out cost based on all the ingredients you have to buy even if you don’t use up all of them since it’s not like you can order half a box of Borax. So, I’ll use Amazon’s prices for simplicity.

If you purchase through the links above on Amazon, you get 6 bars of Dr. Bronner’s soap, 55 oz of Arm & Hammer Washing Soda and 76 oz of Borax for $42.37. This qualifies for free shipping so be sure to choose that option because Amazon will automatically choose standard shipping for you. Just click the free Super Saver Shipping option (5-8 days).

I love Amazon because for supplies like this because it’s no more expensive than going to the local super-store, and typically you’ll receive the items in less than a week. I’m not crazy about supporting big businesses, but for my laundry detergent I’d be buying those ingredients at Walmart otherwise so I prefer Amazon and not wasting half a day in Wally-world.

These ingredients will give you enough to make 6 batches of laundry detergent. You’ll have Borax left over (which you can use for a multitude of household recipes!) I would just go ahead and use the entire box of Washing Soda (close to 7 cups) and all 6 bars of soap, and just measure out 6 cups of Borax.

There are 16 tablespoons in 1 cup. Each batch of laundry detergent yields 2.5-3 cups so six batches will give you 15 cups conservatively. Six batches = 240 loads (15cups X 16TBPS per cup) That comes out to $.18 per load, and I just rounded up to $.20.



Buy the ingredients on Amazon in less than 5 minutes. Grating soap and mixing ingredients takes about 30 minutes. I grated 3 bars of soap and mixed up 3 batches of detergent this morning in about 20 minutes but if you ordered enough for 6 batches, you’d probably spend close to an hour including order time, grating time and mixing up the ingredients.
