My fav still is Wolfgangs Spot Remover, it is one tuff cookie. I have used the DP with nice success but it has a chemical smell that bothers my nose, unless allowed to fully dry outside the car.
I will say a wife, a baby, and neutral interior do not go well together without interior cleaners. I also use a mixture of woolight/water on headliner with great success. Scothgard has been the savings grace in a couple of instances. Just remember to re-Scotchgard areas that have been cleaned.
