I have been very pleased with the results of my home-made laundry detergent and would encourage you to give it a try if you are interested. It was easy to make and does just as well as my regular laundry detergents (most recently: Surf) at cleaning the clothes. The washing soda and borax I found at the grocery store in the laundry section (about $3 each and they will make a few batches of detergent). The clothes come out smelling nice and fresh.
2 c. finely grated bar soap (I used Dial)
1 c. washing soda (a.k.a. sodium carbonate - also used in pools)
1 c. borax
mix well and store in an airtight container
use 2 T per full load
FYI - I used this detergent to clean my CLOTH DIAPERS and they came out just as clean! (still did the extra rinse with 1/4 c. vinegar)
