I've had some people email me and send me Facebook messages about this. (you don't have to be shy about commenting on here, folks :)) So I thought I'd clear up some questions.
The recipe that I made and used was this:
12 cups Borax
8 cups Baking Soda
8 cups Washing Soda
8 cups Fels Naptha soap-- grated
I cut it down and only made 1/4 of this recipe though. I REALLY like it. I researched it some and have found that it is supposed to do fine in both hot and cold water. The only "hard" part was grating the soap. I just used a cheese grater. It took me maybe 10 minutes to get 2 cups. I did read up on it some more and people suggest that you grate it using the smallest grate you have. That makes it dissolve easier and faster.
My disclaimer is this-- it is working great for me. Everything I have read online says that it works great. I have seen nothing that makes me weary. However, that's where my expertise ends. I am no chemist or expert.. I'm just a cheapskate with some dirty laundry :) I am using this in an HE front loading washing machine. This recipe is naturally low suds, which is one of the big things to look for with an HE machine. (When I used Gain, I noticed that when the load was finished, I'd still have a 1/4 cup of suds in the rim of the door. I don't have that at all with this mixture.)
The next batch I make, I'm thinking about making it with only Ivory, borax, washing soda, and water. (I'm thinking about making the liquid kind next. I might change my mind and just make it powder and without the water) But, so far (4 loads into it) I am REALLY pleased with how this recipe/batch turned out. It is cleaning Dustin's work clothes really well. It basically has three different kinds of stain fighters, so I think it is doing a pretty nice job!
If you decide to try it, tweak it, or find something better, let me know! I'm always on the hunt for a better product/better deal! :)
