I finally switch my kitchen to almost natural dishwasher detergent. Well I call it almost because I read that there are so much debate about Borax.
At first I was only using the above mixture. One part of borax and washing soda, and half part kosher salt. I wasn't happy with the smell so I added (below) 2 packs of kool-aid and half part citric acid. I don't mix the salt in my mixture because they turn into clamps. I just add half a teaspoon on every wash.
