made up a batch of this stuff yesterday, and washed 3 loads, works pretty good. sure beats paying $19 for a 150oz tub of tide that only does 72 loads. it should be noted that top loading machines need to use 1/2 cup per load, side loaders only need 1/4 cup.
I didn't quite like the way it gels and sets up, but I got around this by running it in a cheap blender for a few seconds, and packed it into 1 galllon water jugs, now it has a smooth consistency and pours easily, and hasn't set back up.....yet.
