If you decide to make this, go to and look at the pictures that go with this recipe. Just click under the do it yourself button and check it out. My clothes get really clean with this soap and I always pour white vinegar in the washing machine where the fabric softener normally goes. White vinegar strips all remaining soap suds out of clothes and doesn't smell vinegary after dry.

2 (1 qt) Mason Jars
1 Entire bar of Fels Naptha Soap 5.05 oz
3 cups water
1 cup 20 Mule Team Borax Powder
1 cup Arm & Hammer Washing Soda (not baking soda)

How to Make Super Laundry Sauce for Dummies Detergent: Method #1
Unwrap the Fels Naptha soap and cut the bar in half. Take (1) half of the bar and slice it, cutting it into pea sized chunks. Place all of those chunks into a 1 qt mason Jar. Cut up the other half and place those pieces in the second mason jar.
The next day (or several days down the road, depending on your schedule!), open the jar, use a butterknife to make a "criss-cross" pattern to loosen the gelled fels naptha off the bottom when you whip it. Add 1/2 cup borax and 1/2 cup washing soda to each jar.
Add Enough Hot water to bring the level up to the "shoulder" of the Jar
Place the jar on the blender base and Whip until it is light and fluffy with the consistency of Creamy Mayonnaise.

How to Make Super Laundry Sauce for Dummies Detergent: Method #2
This was my "speed" method the first time around . . .
Unwrap the bar of Fels Naptha soap and cut it into chunks. Place those chunks in a Ziploc baggie and add 2 cups of water. It doesn't have to be hot or cold, just your basic plain old tap water will do fine. Remove as much of the air as possible from the bag and seal it shut. (This takes all of 30 seconds).
Set is aside for 48 hours.
Once the fels naptha has set for 48 hours (or more- it's fine if you forget it for a few days) Gently palpate the bag -squeezing any lumps to squish them. You want the contents of the baggie to be uniform without big chunks. (This takes about 20 seconds)
In a Medium size bowl combine borax and washing soda powder. Add 2 cups of boiling water and stir well to combine. We simply heated the water in the microwave in a pyrex measuring cup for 2 minutes.
Snip the corner of the baggie off and squeeze the fels naptha into the mixing bowl containing the dissolved borax/washing soda. Mix well with a spoon or spatula or a whisk- whatever you happen to have on hand will work just fine. (this takes about a minute)
Pour the mixture evenly into 2 ( One Quart) mason jars. Add enough water to bring the contents of each jar up to the "shoulder" of the jar, so that it looks like this:
Put the jar onto the blender and whip until smooth and creamy throughout. Ours took about 25 seconds per jar.

The detergent is Smooth and creamy with the same Look and consistency of Mayonnaise.

Unscrew the blender blade, attach a canning jar lid and cover and that's all there is to it! You've just made enough Heavy Duty Laundry Detergent to wash 128 Loads of Laundry for about $1.76 and in less than 10 minutes flat.

By the way, it is smooth and creamy like mayonnaise after it is freshly whipped, but will thicken as it sets and must be stored with a cover on. A repurposed parmesan cheese lid works perfectly. (Thank you to Southern Belle for this great tip!)

How to Use the Homemade Super Laundry Sauce for Dummies:
(View FAQ here)
To use, add 1 Tablespoon to a load of laundry in any type of machine, conventional, Front Loader, High Capacity & High Efficiency (HE), etc. Do not add the detergent to the "detergent compartment" but instead directly with the dirty clothes. (It WILL get stuck in the compartment, I can assure you!)

Be sure to label the jar to prevent accidental ingestion!!
We have created these cute labels here if you'd like to Print them out to attach to your own Jars.
Here is EXACTLY how I use our detergent:
Fill the machine with dirty clothes
start the water, (hot- Cold- or warm- doesn't matter)
Measure out 1 Tablespoon (literally) of super laundry sauce
stick the measuring spoon of detergent under the running water, let it fall off the spoon.
Close the washer lid, go away and do something else while the machine runs.

Tips and Tricks, Troubleshooting & Other Thoughts and experiences:
Do NOT Use Baking Soda or Oxyclean in this recipe hoping it will be an added "Boost". Your jars will likely explode within 7-10 days in storage
This can be stored indefinitely. It does become slightly firmer but still melts fine in the washing machine water, both hot or cold. Be sure to store it with a lid on though, once it dries out, it's effectiveness is greatly reduced. Again, repurpose the lid from a container of parmesan cheese and you'll be good to go!
Fels Naptha Can usually be found in the Laundry Detergent Isle of the Grocery Store for about $1 a bar, or it can be found online here.

Budget101 Budget Breakdown:
Fels Naptha .99 bar Borax 76 oz box = 9.5 cups $3.29 box = .34 c per cup Washing Soda 55 oz box =6.875 cups - $2.97 box = .43 per cup -------------------------------------------------------------------------------

Total Expense for 128 loads of Laundry = $1.76
We're really hoping that you find these 2 different "speed" methods to be easier and less time consuming for you!
