I love making my own cleaning supplies. One of my favorite homemade cleaning solutions has been homemade laundry detergent. For months I have been making laundry detergent out of Fels Naptha bar soap, Borax, Washing Soda, and water. I worked out the math for the recipe I was using - $1.88 for 3 gallons/128 loads of Laundry Detergent. The best part is that the detergent works really well. I love it! So then I was browsing Pinterest and came across a post for "laundry sauce" from budget101.com. I was intrigued. Laundry sauce is just like the detergent I was already making only super concentrated. It has the same amount of Fels Naptha, Borax, and Washing Soda, but much less water. Instead of 3 gallons of detergent, I would end up with only 2 mason jars, but still be able to do the same amount of laundry.
How to Make Laundry Sauce
To make this wonderful laundry sauce, start by grating a bar of Fels Naptha.
Next, bring 4 cups of water to a boil in a large pot. Add the Fels Naptha and allow to completely melt over medium heat.
Once the Fels Naptha is melted, it's time to add 1 cup each of Borax and Washing Soda and continue cooking for about 5 more minutes.
Once all the ingredients are mixed together, remove the pot from heat and allow to cool slightly.
The next step is where I did things a little differently than the instructions on budget101.com. Instead of dividing the detergent between 2 mason jars, I put the detergent straight into my blender.
Leave the detergent alone for 3 - 4 hours. The detergent will separate into 2 layers.
Let me reiterate the 3 - 4 hours. I think I waited a little too long because the top layer hardened more than I would have liked. Next, the layers need to be blended back together.
Like I said, I waited a little too long, and had to keep scraping down the sides of my blender. Be careful when beginning to blend. I accidently splashed out some of the liquid when I tried to stir the detergent before blending.
After the laundry sauce is all blended, divide it between 2 mason jars. I simply used a rubber spatula to do this.
Since this laundry sauce looks so much like mayonnaise, make sure to label it 🙂 To use the laundry sauce, add 1 Tablespoon per load of laundry. Since the sauce is so thick, I hold the tablespoon under the water as it runs into the washing machine.
I have already done several loads of laundry with this laundry sauce and as you can see, it has hardly put a dent. I'm very happy with this laundry sauce. It works wonderfully and takes up barely any space. Love it!!!
