Laundry Detergent recipe

One of my most tried and true green efforts recently has been with the home-made laundry detergent, so I thought I'd share the recipe. First, a quick pros and cons list:

Pros: 

All-natural

Biodegradable

Safe

Gentle

Effective

Reuse containers

Cons:

Hardens and needs to be broken up

Occasionally lumps of detergent remain in wash after load is done

Recipe makes small amount of detergent

Recipe:

1/4 cup castile soap (I like peppermint)

1 cup baking soda

1 cup washing soda

1 cup white vinegar

Mix the castile soap with the powders. Add vinegar (it will foam up, then settle down, just mix). Stir til completely combined. 

At this point I leave it, and it hardens. If you keep mixing through the hardening process you can break it up right away. It becomes a lumpy powder. I have yet to perfect the process so it all gets crunched up to a thin powder, but honestly, I don't have time at the moment, and it works well anyhow. 1/2 cup in a regular size load does the trick. Makes about 5 loads worth...something like that.

I've been using this detergent for weeks now, with great results.

If you try it, let me know what you think.
