The sweeping motion is key—one pass across the cabin and the stale fast-food smell is just gone, not covered up. I’ve gone through two cans already and the fresh scent lingers longer than I expected for an aerosol.
I keep a can in the car and one by the kitchen trash, and a couple of sweeps really does clear out stubborn smells instead of just layering over them. The light fresh scent lingers for a good while without getting cloying, which is exactly what I want for a six-pack that'll last me months.
The OdorClear spray actually works—after a quick sweep across the backseat, the stale fast-food smell is just gone, not covered up. The light fresh scent lingers for a few hours, which is perfect for a quick refresh before picking someone up.
