So I surf pintrest as well as here and I thought this might be the perfect simple thing for me to write my first instructable. This is a simple and very cheap way to make laundry detergent.

Step 1: Bill of Materials

1- bar Fels-Naptha
1- cup Borax
1- cup Arm & Hammer washing soda
2- 1 quart mason jars

Tools
Blender or Hand mixer

Step 2: Prep

To make everything simpler as you add it let's prep all of our ingredients.

take 1 cup Arm & Hammer washing soda and 1 cup Borax and mix well. set aside.

Shred or grate the ENTIRE bar of Fels-Naptha into another mixing bowl.

measure 4 cups of water and place in a pot bring to a boil.

Step 3: Melting the Fels-Naptha

after your water has come to a rolling boil add the Fels-Naptha and stir continuously. This will take about 15 min to fully dissolve.

Step 4: Adding Borax and Washing Soda

Once your Fels-Naptha has completely dissolved remove from heat and stir in the washing soda Borax mix.

Stir until you can feel that it is completely dissolved into the solution.

Step 5: Pour Equally Into Jars

once the washing soda and Borax have completely dissolved pour equally into the mason jars.

add water to bring the level to about the shoulder of the jar or 1 1/2 inches from the lip of the jar.

Step 6: The Wait...

flip your jars upside down and wait... 4 HOURS

the soap will begin to seperate. I forgot pictures from after the wait but the bottom will look like vegetable oil and the top almost like curdled milk.

You can wait longer but after 4 hours you get a grainier mixture.

Step 7: Blending

For this part use what works best for you. At first I placed the blades from my blender on the mason jars but was not happy with how well it mixed....

So I scooped it all from both jars into a big mixing bowl and used a hand blender to mix it all into a nice smooth cream... about the consistency of mayo.

Step 8: Jar and Use

scoop final cream back into Jars and label.

when adding to wash simply add one tablespoon directly to laundry by placing under the water as it is filling the tub... and there you have it. Super cheap and simple. All of the ingredients cost under $10 at walmart and for 124 loads... next batch all I will need is a single bar of Fels-Naptha which was 97 cents. not bad if I do say so myself...

let me know what you think of this instructable ... I know I forgot to take pictures near the end and will try better next time or when I make the next batch I'll edit and add to this post
