Well, after making our own laundry soap I decided to make some homemade dishwashing detergent. Here is the recipe I used:
One and one half cups of Borax
One and one half cups of Baking Soda
One half a cup of Salt
I just poured it into a dispenser and shook it up real good. The Borax is toxic if ingested, but so are other detergents. Just keep it away from little explorers. ;) Also, it is recommended that you scrub the food off the dishes before washing, but we always do that anyways.
