{ Homemade Laundry Soap }

I know this recipe is used by many of my friends and fellow bloggers, but I have been asked to post the recipe so here you go!

EDITED: Yes, Wal-Mart carries the Fels-Naptha as well as the Super Washing soda.
This is also can be used in any HE washer. 

If your not feeling in the mood to make soap but need a good stain stick:
the Fels Naptha Bar soap is the BEST STAIN STICK EVER.
Just get it wet and rub into any stain. Brinley got chocolate on her new Aeropostale shirt which she informed me of after it had dried, so I just rubbed it with the Fels naptha and it disappeared while I was rubbing it. Amazing stuff.
Oh and I also still use Fabric Softener when I launder my clothes because I just love the stuff.

Liquid Laundry Soap-Family Sized Batch

1 bar grated Fels Naptha soap

5 gallon bucket

1 cup washing soda (Again, Arm and Hammer)

1 cup 20 Mule Team Borax

4 1/2 gallons water

Put grated Fels Naptha in saucepan and cover with water. Heat on low until dissolved. Fill bucket 1/2 way with hot water and add soap. Stir to combine. Add 1 cup washing soda and 1 cup borax and mix well. Fill bucket with more HOT water (I add enough water so it reaches the rings near the top of the bucket) As it cools, it will thicken.
If mixture becomes too thick, add hot water to thin it to desired consistency. May be used immediately. Mix well before each use. Use 1/2(normal) to 1 cup per load (heavy). Cost per load .04

Edited to add:
TIPS:
When mixing the melted soap into the hot water, it's best to add some boiling water to the bucket, it helps break down the lumps better.
I ladle my soap into a used Orange juice container as shown above and just give it a good shake before using.

1/2 cup washing soda

1/2 cup 20 mule team borax

To make a large batch - grate 6 bars of Fels Naptha Soap and then add 3 cups of Washing Soda and 3 cups of 20 Mule Team Borax. Mix well and store in covered container.

TIP: The above recipes will NOT make suds in your washer so don't be alarmed. Fels Naptha Soap is a pure soap and typically makes little or no suds in the water. This makes it perfect for use in the new HE washers as well as traditional washers. You will also notice the need to either reduce your laundry softener or in most cases you can even eliminate the use of softener completely, depending on your preference.

ANOTHER TIP: After this cools down it will be a huge mass o' congealed soap. Get your whisk out and get your hand down in that bucket and whisk, whisk, whisk! You will not be able to get this to be smooth like a store bought liquid. 
BUT
 whisk it enough to put it into another container using a funnel 
(mine is in an old orange juice container). 
When it's in the container  you can shake it up, that will help it break down even further. I usually have to shake it a little everytime I use it.....
