Homemade Dishwasher Powder

I've begun to really get into natural/homemade cleaners. I've scoured the internet for recipes and had fun using them. Here's what I use instead of Cascade:

1 cup borax
1 cup baking soda
1/4 sup salt
2 packages of lemonade kool aid (may use 1/4 cup citric acid)
30 drops of essential oil (I don't do this)
Put all ingredients into a large plastic container with a lid and shake it up.
Use 1 tablespoon per load.
I also use white vinegar in the rinse dispenser instead of Jet-Dry.
** When my last containers of Comet run out, I'm going to try using this as a scrubbing cleaner.

Here's the website I got this from: www.thenewhomemaker.com/dishwasherpowder
