I found a recipe for dishwashing soap here. I want to do some changes on my next go round. I think I could do with less lemi shine since my town water isn't as hard.

This is what you need. It's a lot like the laundry soap, just a few extra things.
Stir all the ingredients together and this is what you get. Note...I halved the recipe I found so it would fit in my 1 quart jar. It has a tendency to harden, so you have to shake it often.
