Homeade Laundry Detergent

Task 1: Cut the cost of doing my laundry.

Unfortunately I live in a fourth floor walk up in Brooklyn so I cant save money by avoiding the laundromat but I am going to try making my own detergent.

I have been too a few websites and really like that the site below has 10 recipes:
10 Home Laundry Recipes

So stayed tuned as I give this a try this weekend!
