How to Make Liquid Laundry Soap


It’s January. Lots of us are working toward goals for better living as part of a New Year’s resolution tradition. If your resolution involves saving money or living healthier (or perhaps tackling one of our easy-peasy Resolutions You Can Keep to build your confidence) you should check this out: Yesterday I made homemade liquid laundry soap.

The process was just as easy and fast as when I made powdered laundry soap last year. I love that the powdered version takes up less storage space, but I have to say that I’ve been disappointed with it not dissolving in cold laundry loads a few of times. Since I had a stash of partially-finished dry soap – and the recipe for liquid soap uses the same ingredients – I decided to give the liquid version a try. This recipe works for both traditional and HE washing machines.

Homemade Liquid Laundry Soap

(original recipe found here)


4 Cups water
1 bar natural soap (such as Fels Naptha)
1 Cup Washing Soda
1/2 Cup Borax

Yield: 10 gallons of laundry soap

To Use

For Traditional Washing Machines:  5/8 Cup per load (Approx. 180 loads)

For HE/Front Load Washing Machines: 1/4 Cup per load (Approx. 640 loads)


Pour water into a medium-sized saucepan. Grate the soap into the saucepan. My cheese grater made the soap extra-fine; you don’t need yours to be quite this crumbly.

Heat medium-low and stir continuously until the soap is entirely dissolved/melted. There shouldn’t be any shavings or chunks left.

Fill a 5 gallon bucket half full of hot water. Add the soap mixture, the washing soda and the Borax.I already had a container will 1 box washing soda and 1 box borax combined so I added 2 cups of the mixture, leaving me with extra-boraxy laundry soap (because that’s a word, right?).

Stir well until all the powder is dissolved. You can use a long spoon or perhaps a mop handle to reach the bottom. Once the powder is dissolved, fill the remainder of the bucket with more hot water. Stir it all together one last time.

Cover the bucket and let it sit overnight. Here’s what mine looked like this morning:

It’s natural for it to develop little globs of gel. Stir it up one more time, then fill a closeable container half-way with the mixture. Good choices are an empty, clean commercial laundry container, an empty milk jug or a glass jar. For now I’m using these 1 gallon containers but will probably switch to milk jugs as we finish up our milk!

After adding the soap mixture to your new container fill the other half of the container with water.

If you’d like, you can also add 10-15 drops of essential oil per 2 gallons after the soap has cooled. I don’t have any essential oils so I skipped this part.

That’s it! Stir/shake before each use because the soap will gel over time.

For 180 loads, that’s a time investment I can handle! I can’t wait to see how it works… which reminds me… I need to go… I’ve got some laundry to do.
