V.W.
Shout before it goes through the wash the first time. And by that I don't mean yell...I mean "Shout" the laundry spray, lol.
I used it with both my kids and if you use it before the clothing is washed there is pretty much nothing it hasn't gotten out. And with grease, it will get it out in a 2nd wash even after the item has been through the dryer.
