Homemade dishwasher detergent

All I can say about this is that it is EASY and cheap! Not to mention that it's free of harsh chemicals! I was skeptical but it really works... Glasses were sparkly clean! Planning to try vinegar as a rinse to make sure there are no water spots left in dishes!

1 cup borax
1 cup soda
1/4 cup salt
2 pkgs unsweetened Kool aid lemonade.
