After a few rounds of using it, people start noticing the room differently. The bed feels fresher. The air feels less stale when they wake up. Even the simple act of walking in after work feels less like entering a trap and more like entering a place that was actually cared for.
That is the real payoff: a room that stops announcing every bad smell it has ever collected.
One small detail changes everything
The setup only works when the lemon is cut deeply enough for the salt to reach the flesh. A shallow slice leaves too much of the fruit sealed off, and then the scent release turns weak and lazy.
Cut it into quarters, sprinkle the salt where the exposed fruit can grab it, and place it where air actually moves through the room. Near a doorway, beside a bed, or close to the worst odor source is where it earns its keep.
