I have a new favorite air freshener. I took the rind of one orange and poured white vinegar over it in a seal-able container. I set it in the fridge for a week. Then I rinsed out an old febreze bottle. Filled it 1/2 way with cold water and the rest with the orange vinegar. I then used it as I would febreze. It smells so good! Took the yucky smell out of my house and left a clean citrus smell instead. I refilled the orange rind container to use again in a couple of weeks.
