I had this idea after I posted last night. I make my own room spray, which is 1.5 cups filtered water, 1/2 cup vodka, and 1 tsp essential oil. Before you freak out, the vodka helps keeps the water from being "too wet" and soaking fabric. I use lavender oil at home, because I love the smell. I don't notice much of the smell, but I'm sure it would be a different story if it was another type of oil. I wonder how using just vodka and water would work, for neutralizing odors? Of course, you don't want to send dolls to children smelling like a distillery....
