All you need is some LIQUID FABRIC SOFTENER, some water and a spray bottle. Pour a few tablespoons of the fabric softener in the bottle, add water until nearly full. Shake well before each use. Works just like the expensive fabric freshener sprays! (Sort of like Febreeze/Febreze spray...also is a great way to use up a little bit of leftover fabric softener liquid.)
