We all know how to use a room spray, However Dunn Homemade's  are unique because I only use 3 ingredients. With my formula you only need 1 to 2 sprays per room and only 1 spray per linen. My spray starts with distilled and filter water, then I add 1 tablesppon of 70% rubbing alcohol and the homemade scent oil that is described above. I have tested these bottles and you get 450 sprays out of each. ( feel free to do that math) Shake and spray ....
