Homemade Laundry Detergent

3 Ingredients:

Soap: A whole bar of Ivory soap.

Washing Soda: Found on the laundry aisle - Arm & Hammer Washing Soda. THIS IS NOT BAKING SODA!

Borax: Found on the laundry aisle - 20 Mule Team.

Recipe:
1 bar Ivory soap
½ cup washing soda
½ cup Borax powder
2 gallon sized bucket

Grate the soap and put it in a sauce pan.
Add 6 cups water and heat it until the soap melts.
Add the washing soda and the borax and stir until it is dissolved.
Remove from heat.
Pour 4 cups hot water into the bucket.
Now add your soap mixture and stir.
Now add 1 gallon plus 6 cups of water and stir.
Let the soap sit for about 24 hours and it will gel.
You use ½ cup per load.

I also found another one that I haven't tried yet:

Same ingredients.
Grate the soap.
Add the Borax and washing soda.
Shake well.
You use 1-2 Tbsp per load.
