I've been making my own homemade laundry soap for quite a long time now. I love the way it works, but I found that I sometimes didn't care for how long it took to mix up a batch. I've been playing with the recipe a bit, and have changed it up a little. Not too much, but I did decrease the amount of vinegar slightly, to about a cup and a half instead of 1-3/4 cups. I found that this small change does make for faster mixing, and it still works just as well!
