I like this concentration the best. I have played with bunches of recipes and this is the one that I was most happy with the results. The whites are great and the laundry in general is just much cleaner. This is very inexpensive and works great. (I found the washing soda at my local Ace Hardware store. The Fels Naptha and borax are in your local grocers laundry section.) Enjoy!
