Homemade Laundry Detergent! (To be tested!)

Okay. I know what you are thinking. I'm all for "greener" choices, but this seems to be going a little too far. I personally can't take credit for even considering this recipe. Doug's cousin mentioned it to me, and I thought it sounded cool but Doug was kinda against it.. thinking that it wouldn't be good for the machine.. At that point I kinda dropped it, and them out of no where 2 other ppl mentioned it to me. After reading online and watching some youtube videos. (I particularly like  http://www.youtube.com/watch?feature=player_profilepage&v=lvBqold9ekA
)

I convinced Doug to let me give it a try! I intend on letting you know how it works out! I am particularly interested/concerned on how my sons skin will tolerate it! He has baby eczema and suggested to use Ivory soap which incidently is an ingredient in this recipe!

The recipe comes from the Duggar's website. (Yes, those Duggars!)

• 
  Homemade Liquid Laundry Soap- Front or top load machine- best value
  
  4  Cups - hot tap water
  1  Fels-Naptha soap bar
  1 Cup - Arm & Hammer Super Washing Soda*
  ½ Cup Borax

  -Stir and fill a used, clean, laundry soap dispenser half full with soap and then fill rest of way with water. Shake before each use. (will gel)
  
  -Optional: You can add 10-15 drops of essential oil per 2 gallons. Add once soap has cooled. Ideas: lavender, rosemary, tea tree oil.
  
  -Yield: Liquid soap recipe makes 10 gallons.
  
  -Top Load Machine- 5/8 Cup per load (Approx. 180 loads)
  
  -Front Load Machines- ¼ Cup per load (Approx. 640 loads)
  
  *Arm & Hammer "Super Washing Soda" - in some stores or may be purchased online here (at Meijer.com). Baking Soda will not work, nor will Arm & Hammer Detergent - It must be sodium carbonate!!
  
  

Once I make it, I'll update and review! :-)
