Homemade Dishwasher Detergent
1–box of Arm & Hammer Super Washing Soda (I found mine at Kroger in the laundry aisle)
1–box of 20 Mule Team Borax
1–box of coarse Kosher Salt
1-container food-grade Citric Acid = I had some already, but you can find it online (Amazon.com/ebay) extra cheap, or you can find it in spice specialty stores. Kroger has it sometimes, and it's either called Citric Acid or Sour Salt. If you cannot find this you can substitute 2 lemon Kool-aid packets per batch that you make. They have to be lemon, because otherwise, they'll discolor the inside of your dishwasher.
1 – gallon of White Vinegar
In a container with a lid (Old coffee cans work great) mix:
1/2 cup washing soda
1/2 cup borax
1/4 cup kosher salt
1/4 cup citric acid
Shake well! That's it! When you pour it into your dishwasher cup, use about 1 tablespoon of the mix. It will clump together, but that's fine. It's because of the citric acid.
For the rinse aid, simply fill up your rinse aid compartment with vinegar. Not only does it keep your dishwasher clean and deodorized, it's great for the dishes.
