I tried my hand at making dishwasher detergent and it hasn't gone well. I started with a recipe from the book Green Clean (1 c. Borax and 1 c. Washing soda). We use vinegar as a rinse agent as well. Most of the dishes came out with a powdery film on them. The book suggested to add a little more washing soda if this happens. I did, and the dishes still had a powdery film. So I tried a different recipe that also used salt and unsweetened lemon Kool-Aid (for citric acid). There was definitely less of a film on the dishes this time, but it was still there.
Is there another recipe that someone has tried that might work better? I did see a recipe that uses a few drops of Dawn, but I have heard such terrible things about that product that I don't really want to go there. Would a castile soap like Dr. Bronners help? Or would that ruin my dishwasher?
We do have hard water, so maybe I just need to suck it up and buy the expensive store-bought EF detergent.

The EFF just reposted her recipe on her facebook

I just bought teh lemi shine to try it when we run out of our cascade.
This is the recipe I used, and I had no film on my dishes when it was done. I was thrilled.
Before, I used Method, and it worked well. Cascade was always a disaster for us- DH preferred it but it always left film and drove me nuts.
