I don't know if any cleaning products will really get rid of the stain, though I imagine you can use a straight razor blade or knife point to make a small hole in the material to clear the air bubble if it's actually full of air and not just warping of the material.
There are warnings on those air fresheners not to let them come in contact with interior surfaces for this exact reason.
I found this using some Google Fu, and while it's not directly applicable to car interior surfaces (and the increasingly severe methods go well beyond what car interiors were meant to handle and remain intact) the first suggestion might end up working for you without risking damaging the material further.
