This is to be used for your automatic dishwasher. It works just as well if not better than store bought brands, in my opinion.
1 cup borax (found in the laundry aisle)
1 cup baking soda
1/4 cup salt
2 packets of Kool Aid (or 1/4 cup citric acid, found at brew stores...I find the Kool Aid easier and cheaper)
Put 1 Tbl in the the wash compartment and 1/2 Tbl in the pre-wash.
Put 1 Tbl vinegar in the "jet dry" compartment. (Be careful not to spill the vinegar into the wash compartments.)
