That's what I use, as well - however I don't use it on my whites. I've found, over time, it greys my whites, so I use normal soap for them, only, but it really works well. I also add about 1/4 C of baking soda for a boy wash when it's stinky clothes - helps freshen the load.
I also use a
Downy Fabric Softener ball with vinegar for softening clothes and a better rinse out of soap residue (I don't use fabric softeners of any kind).
