2 cups of Borax
2 cups of Baking Soda
4 small packets of sugar free lemonade Kool-Aid (you can also use 4 tablespoons of citric acid–if you can find it)
Mix everything together (except vinegar) by either dumping into a big bowl and stirring it really well or dumping it into a container with a lid and shaking it up. You can keep it in your lidded container or re-use your old detergent box.
Use 2 tablespoons per load. (1 tablespoon in the open cup and 1 in the closed locking cup) Pour some White Vinegar into your rinse aid receptacle and your glasses will come out sparkling! (If your dishes end up covered with a white residue, you probably have hard water and need to experiment with the amount of Borax to use.)
