Dishwasher detergent

Once in a while, there is a little more month at the end of my money...and I need to do dishes, but really dont want to spend a ton of money on dish detergent. So I needed to play around with some homemade options, when this one came up...

2 1/2 cups washing soda (crystals)
2 1/2 cups borax
5 -7 drops essential oil (optional but I use lemon oil)

Directions:

Put all the ingredients in a food processor and make into a finer powder... put in a ziplock bag or airtight container... use 1 1/2-2 tablespoons per load. You can use white vinegar in the rinse aid dispenser for sparkling dishes!!
