Nuts about Soap!

So, I've been wanting to switch over to using Soap Nuts for all my laundering, instead of using commercial detergent.....and I will start using them today!!!! I will let you all know how well I like them, as soon as I have used them enough to have a valid opinion :)
Here is a picture of them..

All I will have to do is put 4-5 nuts in the cloth baggy and drop it into my washer. I'll reuse the same nuts until they show signs of disintegrating (which should be every 10 washes or so). I'm quite excited about my nuts, maybe I'm a bit nuts....BUT, they will save us money and are more Eco friendly, as well.

Question for you:
What natural cleaning agents are your favorite?
