Make your own dishwasher detergent!

I love this recipe and it works great. It cost about $13 all together to make and should last 6-9 MONTHS. Here's the recipe:
1box of borax
1box of Arm and Hammer washing soda
24 packages of unsweetened lemonade drink mix
3 cups of Epsom salt
Mix all together and store in a container. Use 1 tablespoon per load. Use Lemieux Shine rinse aid as well to take care if spots. Super easy and I was able to get all the ingredients at Walmart.
