Homemade Powdered Laundry Detergent

I google this recipe, and now I can't remember the exact website I got this from, but just so everyone knows, I did not make this recipe up. So... first you need to buy the following ingredients. I purchased them all at Winco in the laundry isle.
3 Boxes Super Washing Soda
2 Boxes Borax
4 Bars Fels Naptha (or another washing soap)
2 Cups Baking Soda

 Then, you want to grate the fels naptha bars. I did this in my Cuisinart, and it was REALLY fast.

 Finally, mix all the ingredients together in a large bucket.

Now, for the bonuses of making your own detergent. It is better for the environment, your clothes come out VERY clean, you only use a tiny bit (2 tablespoons for a small- regular load) and (1/8 cup for a regular to large load), the batch should last you 6-8 months or longer(I cant say for sure yet, since I just made it this week for the first time), and it is less expensive. To make the whol batch it cost me around $22, and I will have plenty of baking soda to last me 2 more batches. Also, it is supose to be able to work fine for HE since it has no suds. The water just looks kind of merky, so you don't have to add more if it isn't suddsing. It still works wonderfully. The Fels Naptha bar smells wonderful, but if you want to add more scent to it, you can add essential oils. I personally prefer the clean smell of the fels naptha over the lavender or tea tree oil. But it is toally up to you what you want to use. Let me know if you make it and how it turns out for you!
