It's cheap and easy to make your own dishwasher soap. And it works really well. I found that although we reuse as much as possible and grow or trade for a lot of our food, there are little necessities that nickel and dime us into debt. Dishwasher soap is one of those things. All you need to do for dishwasher soap is mix 1 to 1 borax and baking soda. If you're feeling really adventurous, put some white vinegar into your rinse dispenser. Happy Dishwashing!
