Homemade Dishwasher Recipe

OK guys, I have been learning how to make my own household cleaners, and I have to say I am loving it!
It is so easy and it really works well, and it saves a LOT of money!
One of the first things I learned to make was Dishwasher Detergent.
This is SO easy, you can do in it minutes, and be done, and have a really good dishwasher detergent!
All you do is combine:
1 cup Washing Soda (Not Baking Soda)
1 cup Borax
1/2 cup Citric Acid
1/2 cup salt
That's It!
Super easy, huh?
I store mine in a plastic container with a lid. 
Oh, and you only use 1 Tbs. 
I did a lot of research on recipes, and they are all very similar. I did read several times though that some people were having trouble with theirs leaving a white film behind, and I saw that several people said that if you add Citric Acid, it won't do that.
So, I picked one with Citric Acid, just in case!
I got my Citric Acid from The Health Food Center. 
It has worked perfectly! The only time we had any problems was the time that my daughter loaded the dishwasher, and put too much detergent in, and it left a film.
I washed them by hand and it came right off, and I showed her how much to use. 1 Tbs. only , and not a heaping Tbs. , just a loosely packed level Tbs.
If you use the correct amount, AND make sure you have White Vinegar in the rinse agent, you shouldn't have any problems.
At least, I haven't. I know everyones dishwashers are different, so I can't guarantee it, but it has worked for me!
Oh, after I first made the detergent, it seemed to get some moisture in it or something, and kind of stuck together. I stirred it back up, and it was a little different consistency, but it works all the same! lol
I hope you give it a try and love it too!
Let me know!
I will let you know all of the other recipes that I learn to make too!
Stay tuned!
